• a disk read error occurred [closed]

  - by kellogs

  Hi, ¨a disk read error occurred¨ appears on screen after choosing to boot into Windows XP from GRUB. [root@localhost linux]# fdisk -lu Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x48424841 Device Boot Start End Blocks Id System /dev/sda1 63 204214271 102107104+ 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/sda2 204214272 255606783 25696256 af HFS / HFS+ Partition 2 does not end on cylinder boundary. /dev/sda3 255606784 276488191 10440704 c W95 FAT32 (LBA) Partition 3 does not end on cylinder boundary. /dev/sda4 276490179 312576704 18043263 5 Extended /dev/sda5 * 276490240 286709759 5109760 83 Linux /dev/sda6 286712118 310488254 11888068+ b W95 FAT32 /dev/sda7 310488318 312576704 1044193+ 82 Linux swap / Solaris sda is a 160GB hard disk with quite a few partitions and 3 OSes installed.

So far I have tried to ¨fixboot¨ and ¨chkdsk¨ from a recovery console on the affected windows partition (/dev/sda1), the plug off power cord for 15 seconds trick, reinstalling GRUB, repairing the MFT and boot sector of the affected partition via testdisk, what next please ? Thank you!

• KVM Guest Reboot Loop

  - by javano

  I have been pulled into a situation where a KVM server (CentOS 6.2) lost power and upon reboot one of the guests hasn't started up again (XP SP3). I have SSH'ed in and someone must have changed something relating to the hyper visors prior to the power loss, but not rebooted all the guests. This particular guest wouldn't start because it was configured to use /usr/bin/qemu-system-x86_64 which isn't there now (assuming it was before?). I changed it to use /usr/libexec/qemu-kvm as this is what all the other guests on this server seem to be using, and its booting up. Using virt-manager on my local machine I can connect to the display of the XP machine and it gets as far as this screen; http://support.gateway.com/emachines/issues/2-1131285152-01.gif The problem I face now, is that which ever option I choose the machine just reboots. So it's and endless loop. I thought that perhaps a file system error maybe present due to the unclean shutdown. There is an XP SP3 ISO mounted under the guest, which I booted from in an attempt to access the recovery tools, but I don't have the Administrator password! I am out of ideas, and it's turning out to be quite the conundrum. Should I use a 3rd party live CD to test the FS for errors? How else can I trouble shoot these restarts?

• Cloud Deployment Models

  - by B R Clouse

  Normal 0 false false false EN-US X-NONE X-NONE As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective.  This blog is a basic review of  cloud deployment models, to help orient newcomers and neophytes. Most cloud deployments today are either private or public. It is also possible to connect a private cloud and a public cloud to form a hybrid cloud. A private cloud is for the exclusive use of an organization. Enterprises, universities and government agencies throughout the world are using private clouds. Some have designed, built and now manage their private clouds. Others use a private cloud that was built by and is now managed by a provider, hosted either onsite or at the provider’s datacenter. Because private clouds are for exclusive use, they are usually the option chosen by organizations with concerns about data security and guaranteed performance. Public clouds are open to anyone with an Internet connection. Because they require no capital investment from their users, they are particularly attractive to companies with limited resources in less regulated environments and for temporary workloads such as development and test environments. Public clouds offer a range of products, from end-user software packages to more basic services such as databases or operating environments. Public clouds may also offer cloud services such as a disaster recovery for a private cloud, or the ability to “cloudburst” a temporary workload spike from a private cloud to a public cloud. These are examples of a hybrid cloud. These are most feasible when the private and public clouds are built with similar technologies. Usually people think of a public cloud in terms of a user role, e.g., “Which public cloud should I consider using?” But someone needs to own and manage that public cloud. The company who owns and operates a public cloud is known as a public cloud provider. Oracle Database Cloud Service, Amazon RDS, database.com and Savvis Symphony Database are examples of public cloud database services.

Some workloads may be best-suited for a private cloud, some for a public or hybrid cloud. And you might deploy multiple private clouds in your organization. If you are going to combine multiple clouds, then you want to make sure that each cloud is based on a consistent technology portfolio and architecture. This simplifies management and gives you the greatest flexibility in moving resources and workloads among your different clouds. Oracle’s portfolio of cloud products and services enables both deployment models. Oracle can manage either model. Universities, government agencies and companies in all types of business everywhere in the world are using clouds built with the Oracle portfolio. By employing a consistent portfolio, these customers are able to run all of their workloads – from test and development to the most mission-critical -- in a consistent manner: One Enterprise Cloud, powered by Oracle.   /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• Diagnose remote desktop freezes in Windows 7 when no BSOD?

  - by Paul Smith

  Okay, I'm getting no joy from Asus or Microsoft on this, so hoping for some clues on how to narrow down the cause. I have very frequent OS freezes, always & only when running Remote Destkop Client (mstsc) in Windows 7 x64. I never have a bluescreen, and there is never a minidump. The display & input just freezes -- no keyboard, no mouse, and sound will just continue the last wavelength if any. So far, I can't find a way to trap the hang given that there's no bluescreen; advanced startup & recovery settings for system failure are "Write an event" checked, "Automatically restart" checked, and "Kernel memory dump". I've updated to the lasted BIOS, and tried a few different graphics drivers, both generic & ATI. I've also tried disabling Aero, and everything about the remote desktop experience (incrementally unchecked every box in the mstsc - options - experience tab), even disabled/unplugged external monitor to make sure it wasn't a dual-monitor issue. My specs are: Asus G73jh notebook 8GB RAM ATI Mobility Radeon HD 5800 Series graphics (recently tried driver versions 8.791.0.0, 8.801.0.0) American Megatrends G73jh.211 BIOS (7/27/2010) Windows 7 Home Premium x64 Windows Memory Diagnostic passed all of the following at least 3 times with no errors: MATS+ INVC LRAND Stride6 WMATS+ WINVC This notebook is better than most at removing heat (laudable vent design), so I'm not inclined to suspect thermal causes (especially since running 1080p video for hours has never caused a freeze, but mstsc does, reliably, within 5 minutes to an hour). This did seem to start happening after a Windows Update, but I've since reverted every patch applied since a week before the first occurrence, with no joy. (And I'd only had the PC for a couple weeks before that, so it could have been chance + less actual time spent remoting at the beginning.) I'm at my wits end, and I bought this laptop primarily as a remote terminal client (go figure, right?) Any ideas on how to identify the cause of this? Thanks!

• iCloud backup merges or overwrites?

  - by Joe McMahon

  The following happened today (it was six AM my time, so yeah, I was dumb and dropped stitches in this process): A friend had a problem with her iPhone and needed to reset it. Unfortunately she did the reset while connected to iTunes and the restore process kicked in. In my sleepy state, I told her to go ahead. She did, and restored the most recent local (iTunes) backup (from July last year - she doesn't back up often, as she has an Air which is pretty full). During setup on the phone, she was prompted to merge data with the iCloud copy, and did so. There was no "restore from iCloud" prompt. Obviously I should have made sure she was disconnected from iTunes before she did the reset, or had her set it up as a new device and then restored from iCloud, but water under the bridge now. (Side question: could I have had her disconnect and then restart the phone again and avoid this whole process?) The question is: was the "merge" that happened in this process a true merge, or a replace? Her passwords for Mail were wrong, since they were the old ones from the old backup. If she does the wipe data and restore from iCloud, will she get her old SMSes and calendar entries back? Or did the merge decide that the phone, despite it being "old" was right and therefore the SMSes, calendar entries, etc. were discarded? As a recovery option, I have a 4-day-old iTunes backup here from ~/Library/Application Support/MobileSync/Backup, but she and the phone are 3000 miles away, and it's 8GB, so I can't easily restore it for her. I do have the option of encrypting it and mailing it on a data stick if the iCloud backup is now toast. Should she try the wipe and restore from the cloud (after backing up locally), or should I just get the more-recent backup in the mail? My goal is to get everything (especially the SMSes) back to the most recent version possible.

• How to repair a corrupted Excel file

  - by SjoerdV

  I'm trying to restore some files for a friend who messed up a USB stick by pulling it out of the computer too soon. By searching invisible partitions I was able to restore the files. All files are intact, except 1 excel file that seems to be corrupted. I've googled about ways to repair an Excel file, because the default repair options in Excel 2003-2010 do not work for this file. I've came across a numerous third-party apps, of which the one seemes to be able to do the job: Recovery Toolbox for Excel. Of-course, this and all other apps I found require a purchase to actually repair the file. It seems a bit silly to pay 30 dollars for a one time thing, and something that is not for myself. So, I would like to keep that as a last-resort option. Is there anything I can try to fix this? I've attached a screenshot of how the file looks when I open it on my OSX when converted to a HTML file (to view the code), for the option that it could be a character set problem.

• Can not boot windows XP from cloned hard disk - what can I do?

  - by Martin

  My configuration: a PC (some years old) with MSI K8N-Neo-4F Motherboard, 1 GB RAM. Disk 1 (Maxtor, SATA II, 250 GB): 2 Partitions, on Partition 1 (48 GB): Windows XP Professional (NTFS) on Partition 2 (190 GB): data (NTFS) I wanted to have a larger and faster disk (the PC is incredibly slow and permanently the disk is rattling when I try to open an application or during Windows startup), so I took Disk 2 (Seagate, Sata II, 500 GB), installed in the PC, created at first a 400 GB-partition at the end of the disk and cloned the data to it, which worked well Installed a swap partition and a partition for Ubuntu Linux 12.10 on the first "part" of the disk so I was able to boot Linux and the old Windows XP with the Linux "System selection" at startup. Now I wanted to move Windows XP to the new disk, deleted the Linux partitions cloned Windows XP to the new disk (with free tools - EASESUS), left both disks in the PC and tried to select the new hard drive during boot as boot partition. This did not work, the PC refused to boot from this second disk. I tried many things like making the boot partition on the 2nd drive "active" in the Windows System Preferences modifying the boot.ini file to boot from the second disk - tried to boot from it, but ended with an error message stating that it was not possible to boot from this disk because of a hardware failure or something else or so removing the original disk and plugging the new one on the same SATA port as the original one - also booting failed with an error message repairing the MBR by booting into recovery mode from the Windows XP Installation CD-ROM, selecting the second disk and doing "FIXMBR" which said that everything was fine with the MBR. after that at least the PC tried to boot from the newer disk and then startup was hanging during the blue screen with the Windows Logo.... no luck. ... deleting the cloned partition and cloning again - this time with Macrium Reflect Free version... - no success during booting. I tried a lot of things with no success, so I wonder what I am doing wrong?! What could I do to successfully clone my Win XP partition to replace the original disk by a larger one which is bootable.

• Broken Vista. Can't open Windows settings.

  - by serena

  My neighbor has a Lenovo laptop with Windows Vista Home Basic. She's a noob and just uses the laptop for internet purposes. She said she had to close down Windows improperly (sometime ago, maybe 6 months) because of system freeze. She realized there's something wrong with her Windows when she tried to open Windows update settings. I took a look at the system and determined the following errors: When I click on Windows Updates, a bare white window opens for a sec. and closes immediately. When I try to open Computer Properties, the same thing happens. (Windows+Break doesn't work either.) When I try to open Bluetooth settings, the same thing happens. So Vista won't let me open any Windows settings, but installed programs work correctly (games, applications etc.). She has no Windows Vista discs since the laptop came with preinstalled genuine Vista. She also has no recovery discs. I don't think there is a system restore point for the time the system was stable. Now what can we do to solve this big problem?

• RAID-capable 3.5" SATA Drives

  - by nroam

  I recently purchased a pair of 1TB Western Digital WD1002FBYS RE3 drives for use in an external RAID enclosure. I have found that they tend to drop out of the array after a while. Thinking it was the enclosure I tried them on another one but found the same issue. So a bit of googling and I found http://www.tomshardware.com/forum/251076-32-raid-issues-western-digital-hard-disk which suggests that: "WD's "RE" (RAID Edition) HDDs support Time-Limited Error Recovery ("TLER" ): http://www.wdc.com/en/products/productcatalog.asp?language=en As a non-TLER HDD fills up with data, the error detection firmware might take too long, and the RAID controller may drop that HDD from a RAID array." So now I wonder what SATA drives have firmware which is compatible with RAID arrays (esp. RAID 1, 5, but not 0)? I have not been able to come up with the magic set of keywords to ellicit the answer from Google. However, various sites suggest that Seagate & Hitachi are in general OK. Does anyone have any generic (or even specific) guidance on how to work out if a drive's firmware may harbour code that is potentially an issue in a RAID0 setting other than stating that it must be 'enterprise' ready?

• Can't install Hyper-V in Windows 8 Pro. Causes boot loop, pain & suffering

  - by Nick

  Hardware: Intel i7 2600K (not overclocked, SLAT compatible, virt. features enabled in bios) Asus Maximus IV Extreme-Z (Z68) 16Gb RAM 256Gb SSD Other non-trivial working parts Adding Hyper-V is causing a boot loop resulting in an attempt at automatic repair by Windows 8 after the second or third loop: I'm trying to get the Windows Phone 8 SDK installed and I've narrowed down my troubles to the Hyper-V feature in Win8. This is required to run the WP8 emulator and there are no install options to omit this feature. My first attempt completely borked the OS as I did not have a recent restore point or system image, so I did a completely clean install and made plenty of backups/restore points. I skipped the SDK install and went straight for the windows feature add-on for Hyper-V. This confirmed that Hyper-V is the issue as the same behavior resulted. I cannot find any hint in the Event Logs. Cancelling automatic recovery causes the same behavior to repeat. I don't have any other VM products installed. My only recourse is to use a restore point, try something else, install it again, and see what happens. No luck so far. I'm on my 10th attempt here. Any help would be much appreciated.

• Suspected Corrupted Windows 7 MBR?

  - by AridDecay

  So, this may not be the correct place to put up my question, but i'll give it a shot. I'm having an issue repairing this computer. It was brought to me with the described issue of 'Not turning on' Later, I found that it would come with the error of 'No boot sector found on internal hard drive.' I assumed it was an MBR issue due to a virus or cutting a Windows update short. I booted into my trusty recovery enviroment and ran bootrec.exe /FIXMBR and restarted -- No luck I started to think (After multiple attempts to get the MBR sorted out, including creating a new boot sector) that the Hard-drive was possibly starting to cave in on itself, so I booted into a linux bootable CD and went to check the SMART data. Odd, say's it's inaccessible. That seems odd to me, considering it's a newer (two years old or so) Windows 7 computer. All new Hard-drives have SMART. So, I checked the BIOS. No mention of SMART anywhere. Greaaaat. I decided as a last-ditch effort to switch the hard-drive type to ATA in the BIOS (God knows why, I was getting frusterated) instead of AHCI. VOILA! It actually attempts to boot, gets halfway through the little windows animation, does an incredibly (Half a second) quick BSOD, and shuts down. Does anyone have ideas on what's going on here? I'm at my wits end.

• Get Matrox Millenium video card working in Ubuntu 9.10

  - by wcoenen

  I have installed Ubuntu 9.10 on an old PC and it is mostly working, except for some heavy drawing defects that show up whenever I start dragging a window or scrolling inside a window or menu. It looks like the video driver copies the rectangle being moved to the wrong location. I have taken a look in /var/log/Xorg.0.log and the following line shows the detected video card: (--) PCI:*(0:0:8:0) 102b:0519:0000:0000 Matrox Graphics, Inc. MGA 2064W [Millennium] rev 1, Mem@ 0xf9800000/16384, 0xfb000000/8388608, BIOS @0x????????/65536 (==) Using default built-in configuration (30 lines) (==) --- Start of built-in configuration --- Section "Device" Identifier "Builtin Default mga Device 0" Driver "mga" EndSection How do I fix the drawing defects? It turned out that the 24 bit color depth (automatically selected by ubuntu 9.10) was the problem; apparantly the mga driver doesn't handle this well for cards with little memory. I took the following steps to resolve the issue (you can skip the first three steps if you already have a semi-working xorg.conf file): Reboot ubuntu in recovery mode, to get a root console without X running. Run Xorg -configure to generate a xorg.conf.new file Copy the file to /etc/X11/xorg.conf with cp xorg.conf.new /etc/X11/xorg.conf (assuming it didn't exist yet; that's why I generated it) Open the new config file with sudo nano /etc/X11/xorg.conf and make sure the screen section is configured for 16 bit color depth like this: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "1024x768" EndSubSection EndSection I can't guarantee those were the only important changes I made - I tried a few things in my attempts to create a valid xorg.conf file. But I'm pretty sure that the screen section was the important part.

• Unrelated Files Corrupted on System Restore

  - by Yar

  I restored OSX 10.6.2 today (was 10.6.3 and not booting) by copying the system over from a backup. The data directories were not touched. In the data directories, I'm seeing some files as 0 bytes, and getting permission-denied errors when copying, even when using sudo cp or the Finder itself. Some programs, differently, take the files at face value and see no permission problems (such as zip), but they see the files as zero bytes, which would be game-over for recovery. cp: .git/objects/fe/86b676974a44aa7f128a55bf27670f4a1073ca: could not copy extended attributes to /eraseme/blah/.git/objects/fe/86b676974a44aa7f128a55bf27670f4a1073ca: Operation not permitted I have tried sudo chown, sudo chmod -R 777 and sudo chflags -R nouchg which do not change the end result. Strangely, this is only affecting my .git directories (perhaps because they start with a period, but renaming them -- which works -- does not change anything). What else can I do to take ownership of these files? Edit: This question comes from StackOverflow because I originally thought it was a GIT problem. It's definitely not (just) GIT. Anyway, this is to help put some of the comments in context.

• Ubuntu 13.10 - How to disable LVM and cryptsetup? cryptsetup: evms_activate is not available

  - by NeverEndingQueue

  I am trying to remove whole drive encryption from my Ubuntu installation. I've run Ubuntu from Live CD, mounted crypt partition and copied it to another partition /dev/sda3. sudo cryptsetup luksOpen /dev/sda5 crypt1 sudo dd if=/dev/ubuntu-vg/root of=/dev/sda3 bs=1M After that I've run boot-repair: https://help.ubuntu.com/community/Boot-Repair Added entry to /etc/fstab: UUID=<uuid> / ext4 errors=remount-ro 0 1 Of course I've replaced with blkid result of my /dev/sda3. I've also deleted overlayfs and tmpfs lines from /etc/fstab. (I've just compared it to content of /etc/fstab in non-encrypted Ubuntu installation and could not find overlayfs and tmpfs). I've chrooted from LiveCD into my system and rebuilt initramfs: http://blog.leenix.co.uk/2012/07/evmsactivate-is-not-available-on-boot.html I've also removed cryptsetup using apt-get remove. Basically I can easily mount my system partition from Live CD (without setting up the encryption and LVM stuff), but can not boot from it. Instead I see: cryptsetup: evms_activate is not available When I've chosen the Recovery mode I've seen this: Begin: Mounting root file system ... Begin: Running /script/local-top ... Reading all physical volumes. This may take a while ... No volume groups found cryptsetup: evms_activate is not available Begin: Waiting for encrytpted source device ... My /etc/crypttab is empty. I am pretty sure that system tries to find encrypted partition, search for LVMs etc. Do you have ideas what could be the problem or how can I fix it? Thanks

• Computer not finding hard drives on boot -sometimes-

  - by todd.pund

  Computer specs: Mobo: Gigabyte ultradurable 3 - GA-970A-UD3 Processor: First gen I7 3.2GHZ Ram: 8GB Kingston DDR3 1066 Video Card: EVGA NVidia GTX 460 1GB Hard Drive: 500MB 7200rpm x2 (can't remember brand, sorry I'm at work.) Last week my developer preview for Windows 8 ran out so I put my copy of windows 7 back on the computer. The computer at that point started suffering from frequent freezing and crashing. When I rebooted the computer sometimes it wouldn't find the system HD at all. When I looked at the post screen it seemed to show that it wasn't finding either of the HDs. Then yesterday when turning on the computer I just got GRUB as a message (not a GRUB prompt, just GRUB) I haven't had a dual boot of Linux for at least a year. I loaded windows 7 recovery console from the disk and ran: bootrec /fixboot bootrec /fixmbr Which did not help. At that point I just installed Ubuntu 13.04 over the windows 7 install and still received the GRUB post. I went into the BIOS and switched the Hard Drive priorities and then it loaded into Ubuntu fine. For several days everything was just hunky dory until I installed the Ubuntu version of Steam, install Portal and tried to run it. At that point the computer froze and after hard rebooting couldn't find the hard disks again. Then after restarting the system it loaded up fine again and no issues since. (I have not tried to launch portal again). My next thought is to remove the system hard drive and try to use the secondary as the master to see if the primary HD is bad. I'm sorry if this has been confusing, I'll answer any questions I can. Any thoughts?

• Lost Windows 7 boot after EasyBCD with EFI

  - by drent

  I've got a Lenovo Y580 with a 64GB SSD and a 1TB HDD setup using GPT and setup to boot from (U?)EFI. I was trying to get my Linux Mint installation on the Windows boot manager using EasyBCD (I didn't realise EFI but it wiped my boot partition/loader and I cannot seem to get Windows back (and I still can't get a bootable Linux Mint). Using the System Recovery utility, Startup Repair can't "see" windows (it might be because I'm using a 7 Pro disk to recover Home Premium?). In command prompt, Bootrec tools don't do anything and bootsect can't run because it says that it's for BIOS only and I've booted with EFI. I can see the EFI data on the 200mb SSD partition using diskpart but I don't know how to add Windows back onto whatever bootloader I have/need. At the moment the only options I can see are: Do a fresh install of Windows and hope that the setup remains as fast as the default one (the SSD is some kind of cache for Windows but I can't quite see how it works given that the rest of the SSD is unpartitioned space). This seems like overkill given that Windows was working fine til EasyBCD deleted it. Try forcing BIOS mode and see if that somehow magically fixes things Try converting from GPT to MBR to try and use the bootrec/bootsect tools (and maybe back again) which seems like a really bad idea. Anyone have any ideas?

• Fixing damaged partition table

  This is continuation of Recover Extended Partition , but this time I have different problem related partition table it self. I managed to restore partition that I needed and backed up files that were crucial to me (at least those that I had space to store somewhere) OK now get to the problem.

• Pull network or power? (for contianing a rooted server)

  - by Aleksandr Levchuk

  When a server gets rooted (e.g. a situation like this), one of the first things that you may decide to do is containment. Some security specialists advise not to enter remediation immediately and to keep the server online until forensics are completed. Those advises are usually for APT. It's different if you have occasional Script kiddie breaches. However, you may decide to remediate (fix things) early and one of the steps in remediation is containment of the server. Quoting from Robert Moir's Answer - "disconnect the victim from its muggers". A server can be contained by pulling the network cable or the power cable. Which method is better? Taking into consideration the need for: Protecting victims from further damage Executing successful forensics (Possibly) Protecting valuable data on the server Edit: 5 assumptions Assuming: You detected early: 24 hours. You want to recover early: 3 days of 1 systems admin on the job (forensics and recovery). The server is not a Virtual Machine or a Container able to take a snapshot capturing the contents of the servers memory. You decide not to attempt prosecuting. You suspect that the attacker may be using some form of software (possibly sophisticated) and this software is still running on the server.

• Cloning to a smaller hard drive with DDRescue

  - by krebshack

  I am currently working with a 700 GB Seagate hard drive that's beginning to fail. I'll call this "SDB" from now on. I'd like to clone it while I'm still able to. However, the only hard drive that I have available is a 500 GB WD hard drive. I'll call this "SDC" from now on. The partition scheme on SDB is as follows: 9.77 GB is allocated to a recovery partition and the remaining 688.87 GB is allocated to a Windows partition. Both are formatted using NTFS. There is no partition scheme on SDC. I know how to clone one hard drive to another using DDRescue but I've only done it using hard drives that are the same size. For your reference, I'll normally use the command "ddrescue -v -r 3 /dev/sdb /dev/sdc example.log". I'd like to know if it's possible to do this with DDRescue. I've read the manual from GNU (http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html) and I haven't seen anything indicating that it is possible. I'm just looking for some confirmation that this is a correct impression. If it's not possible, then it would be helpful if any of y'all would be able to make some work around suggestions. But please don't feel obligated to do that. I don't want to have my one thread bogged down with two many questions.

• Shortcuts located in "D:\Program Data\..." not working even though they're pointing to the right targets (Windows 7)

  - by Kevin

  I just made a fresh install of my windows 7 home premium using my laptop's recovery disks (HP Pavilion dv6-2151cl) using minimal settings. After install, I set up "Program Data" and "Users" to my D partition to save space changing the folders in the registry. Then I updated windows (including W7 SP1), and installed all other programs. After installing all other programs I noticed that the icons of all new programs (not included in the windows install) in "All Programs" had a blank sheet as icon and they don't do anything. Looked into "D:\Program Data\Microsoft\Windows\Start Menu\Programs" in the windows explorer and the same is true there. All the shortcuts in C: and "D:\Users..." work both in the "Windows Explorer" and "All Programs". Also I noticed that the shortcuts do display the right icons inside the "open" dialog boxes. And if I copy the shortcuts in "D:\Program Data..." to the desktop they also work as expected. I checked file association for .lnk and it was OK, but also tried the registry fixers for this file association and they had no effect. There are no missing programs that I can tell in the "All Programs" menu, the just don't do anything if they lay in "D:\Program Data...". Any thoughts on how to make Windows 7 treat shortcuts in "D:\Program Data..." as they should?

• Trying to retrieve data with a thermaltake blacX enclosure: Windows 7 believes the drive to be "uninitialized"

  - by Peeter Joot

  I have a laptop that won't boot. It appears to be a power problem ... laptop auto-turns-off within about 10 seconds of pressing the power button (with power buttons lighted temporarily and no display with or without external monitor). I've followed the dell troubleshooting guide which suggested reseating the memory modules and the hard drives, but that didn't help. Before trying to have the laptop serviced, I wanted to get some data off off the hard drive. I bought a thermaltake blacX enclosure, intending to use this to both use to retrieve the drive data with, and then later use as external storage. Following the instructions (insert cables, insert drive power on) goes fine, and Windows 7 on another laptop installs the device driver software. However, no drive letter shows up in 'Computer'. Under Computer-manage-storage I see the drive is there, and there's an option to "initialize" the drive. The Windows "initialize" dialog gives me the option to pick between "MBR" and "GPT" partitioning, which sounds like a good way to destroy the data on the drive. I'm thinking that I've purchased the wrong device for the job (or that my old drive is damaged). The old drive to recover info from is a Western Digital 500G/7200rpm SATA drive if that is relavent. Both the original laptop and the one I'm using for recovery are running Windows 7. Does anybody have experience with using a blacX enclosure to recover data off an already formatted drive?

• Unnamed, hidden partitions on my 500 GB HD, HP Pavilion dm4 Laptop

  - by emotionull

  I have multiple doubts here. Its a Seagate 500GB 7200RPM HD. I had installed it few months back after my original Laptop HD stopped working. The current drives on my latop, as shown by the Windows Disk Management are: After installing the new HD, I had done a complete clean install of Windows 7 and I didn't create any parition myself, manually. So there are 4 drives. Even previously, before I installed this new HD, my laptop had 4 Partitions. But the there were no un-named partitions like the two in this case. The other two were HP tools and Recovery or something. It was pre-configured, Factory installed Windows. Also, now when I right cick on the unnamed Drives from Disk Management, all the options are greyed out (see image) except the delete partition image. So how do I know what's inside those partitions? Will it be ok if I delete them? I want install Ubuntu and dual boot it with my current windows installation. I cannot do it in current setup as there are already 4 partitions of my HD and if I will try to make a new partition, it will be a logical one (correct me if I am wrong here). So can I delete the un-named, hidden partitions and use them for Ubuntu? A bit unrelated question. As a backup option, can I use the Windows 7's Backup and Restore facility to keep a complete backup of all the drivers and system softwares.

• INACCESSIBLE_BOOT_DEVICE after installing Linux on same drive

  - by kdgregory

  History: My PC was configured with two drives: an 80G on IDE 0 Primary that was running Win2K, and a 320G on IDE 0 Secondary that was running Linux (Ubuntu). I decided to pull the 80Gb drive out of the system, so dd'd the entire 80 G drive (/dev/sda) onto the 320 (/dev/sdb) -- this included the MBR and partition table. Then I pulled the drive, plugged the 320 into IDE 0 Primary, and rebooted. The Windows partition worked at this point. Then I installed Ubuntu into the remaining space on the 320. It works. However, when I try to boot into Windows, I get a BSOD with the following message: *** STOP: 0x0000007B (0x89055030,0xC000014F,0x00000000,0x00000000) INACCESSILE_BOOT_DEVICE Before the BSOD I see the Win2K splash screen, and it claims to be "starting windows" for a couple of seconds -- so it appears that the first stage boot loader is working as expected. Ditto when I try booting in Safe Mode. After reading the Microsoft KB article, I booted into the recovery console and tried running chkdsk /r. It refused to run, claiming that the drive was corrupted (sorry, didn't write down the exact error message). However, I can mount the drive from Linux, and access all files. And for what it's worth, I can scan the drive using the Linux "Disk Utility" (this is Ubuntu, the menus don't show real program names), it claims the drive to be clean. The KB article mentioned that boot.ini could be the problem, so here it is: timeout=10 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows 2000 Professional" /fastdetect Any pointers on what to do next?

• Can I clone my hard drive to an external and boot from the clone?

  - by willbuntu

  First thing: I am not asking what software I'm supposed to use. I already know the answer: Ghost (proprietary), Clonezilla, and dd (if I'm careful). What I really want to know is if it is possible to (essentially) bit-for-bit clone my entire installation (OS, installed software, activation(s), etc.) to an external USB hard-drive, and then boot off of that (if I need to, I know how to edit BIOS settings and use Plop boot manager), and work with it day-to-day as if there was virtually no difference from using my internal HDD now. Again, I'm not asking how to install Windows to an external (because I know I'd need to do some special workaround), I'm asking if I can clone everything and boot off of it. In case you're wondering why I'm going to this trouble: I'm using a Lenovo Essentials laptop that has an unmodifiable partition table (due to recovery crap), and has all 4 of its partitions spoken for (3 primary, one extended, cannot change the extended). Anyway, my thought is that if I can clone everything and boot off of it when I need to, and just have a Linux distro on the internal HDD, then that could work.

• How can I duplicate HBCD's XP boot loader with my MBR?

  - by Warpstone

  I'm stumped. I'm migrating a Win XP Lenovo T500 to an SSD: I copied the XP partition using EaseUS to the SSD. Aligned the boot sector using Gparted The MBR needs to be rebuilt (fair enough) However, all attempts to use the Windows Recovery console hang (both via a boot CD and even when the console was installed as a boot option). I've tried using a bunch of tools to rebuild/replace the MBR, but no dice. They all say the MBR has been fixed, but I cannot load Windows from the SSD. The HBCD's boot from windows option works just fine however. I'm confused as to what HBCD can do that my drive can't. How can I get that functionality on my SSD? Is it a MBR fix I can mirror? The SSD is extremely fast when I do use HBCD to boot up... but it would be nice to not need a token-based access to the machine! :) Note: I know, windows 7 may be worth a fresh install, but I'm trying to avoid the cost and hassle if possible.
