• Need a place to store a few bytes of meta information on storage media

  - by Jason C

  I'm working on an embedded project. I need a place to store some filesystem-independent meta information on a storage device. The device has an MSDOS partition table. The device also may have unallocated space (depending on its size) but it will be TRIMmed (and also may be blown away by new partitions in the future). I need a location on the device that is not unallocated and that has a low risk of being touched (outside of completely erasing the device). The device is only guaranteed to have an MBR at the point the meta data needs to first be written; meaning there are no EBRs/VBRs present that I could use. There are 446 bytes at the very start of the device available for MBR bootstrap code. Currently my only idea is to store data at the end of this block. However, the device is bootable and I have no way of knowing if I'd be blowing away bootstrap code or not. The sector size is 512 bytes and the MBR is the first sector, I'm pretty sure (correct me if I'm wrong) that that means the second sector is available for use by partition data, so I can't use that either. Does anybody have any ideas? I need 4 bytes of space.

• Replace Linux Boot-Drive | ext3 to btrfs

  - by bardiir

  I've got a headless server running Debian Linux currently. Linux vault 3.2.0-3-686-pae #1 SMP Mon Jul 23 03:50:34 UTC 2012 i686 GNU/Linux The root filesystem is located on an ext3 partition on the main harddrive. My data is located on multiple harddrives that are bundled to a storage pool running with btrfs. UUID=072a7fce-bfea-46fa-923f-4fb0827ae428 / ext3 errors=remount-ro 0 1 UUID=b50965f1-a2e1-443f-876f-578b5f93cbf1 none swap sw 0 0 UUID=881e3ad9-31c4-4296-ae60-eae6c98ea45f none swap sw 0 0 UUID=30d8ae34-e2f0-44b4-bbcc-22d761a128f6 /data btrfs defaults,compress,autodefrag 0 0 What I'd like to do is to place / into the btrfs pool too. The ideal solution would provide the flexibility to boot from any disk in the system alike, so if the main drive fails I'd just need to swap another one into the main slot and it would be bootable like the main one. My main problem is, everything I do needs to result in a bootable system that is open to ssh logins via network as this server is 100% headless so there is no possibility to boot it from a live cd or anything like that. So I'd like to be extra sure everything works out fine :) How would I best go about this? Can anybody hint me to guides or whip something up for these tasks? Anything I forgot to think about? Copy root-data into btrfs pool, adjust mountpoints,... Adjust GRUB to boot from btrfs pool UUID or the local device where GRUB is installed Sync GRUB to all harddrives so every drive is equally bootable (is this even possible without destroying the btrfs partitions on the drives or would I need to disconnect the drives, install grub on them and then connect them back with a slightly smaller partition?)

• Linux Software RAID1: How to boot after (physically) removing /dev/sda? (LVM, mdadm, Grub2)

  - by flight

  A server set up with Debian 6.0/squeeze. During the squeeze installation, I configured the two 500GB SATA disks (/dev/sda and /dev/sdb) as a RAID1 (managed with mdadm). The RAID keeps a 500 GB LVM volume group (vg0). In the volume group, there's a single logical volume (lv0). vg0-lv0 is formatted with extfs3 and mounted as root partition (no dedicated /boot partition). The system boots using GRUB2. In normal use, the systems boots fine. Also, when I tried and removed the second SATA drive (/dev/sdb) after a shutdown, the system came up without problem, and after reconnecting the drive, I was able to --re-add /dev/sdb1 to the RAID array. But: After removing the first SATA drive (/dev/sda), the system won't boot any more! A GRUB welcome message shows up for a second, then the system reboots. I tried to install GRUB2 manually on /dev/sdb ("grub-install /dev/sdb"), but that doesn't help. Appearently squeeze fails to set up GRUB2 to launch from the second disk when the first disk is removed, which seems to be quite an essential feature when running this kind of Software RAID1, isn't it? At the moment, I'm lost whether this is a problem with GRUB2, with LVM or with the RAID setup. Any hints?

• How to make a Windows Vista boot / recovery cd from a running system without using an original CD / DVD

  - by Giorgio

  I have just repaired a friends computer (replaced motherboard) and now I am trying to repair the Windows (Windows Vista) partitions. Unfortunately, probably due to the fact that he tried to start it several times after the old motherboard had stopped working (no signal on video) now the partition table or the file systems (or both?) appear to be damaged. I managed to boot Windows a couple of times but could not complete the boot. I tried to repair the partition table and file systems using Linux RIP (booting from USB stick) but the Linux utilities say that the file system is damaged and I should run chkdsk /f from Windows. So I now need a Windows boot CD from which I can boot and run chkdsk or any other Windows utilities that can repair the file system. Is there an easy way to create such a CD? Or can I download it for free somewhere? All the links to Windows Vista boot / repair CD's I have found on the internet refer to non-free stuff. Any hint? EDIT I have a working laptop with Windows Vista installed. So one solution would be to make a bootable CD or USB from it so that I can boot the desktop and run the repair utilities. However, I do not have the Windows Vista installation DVD, because both computers were bought with Windows pre-installed.

• Imac g5 with no OS nor CD drive

  - by sinekonata

  What I want: Ubuntu on a g5 Imac. What I have: An empty PC (Intel g5 17" Imac) with broken CD drive. Its model is A1173. This PC with Ubuntu 12.04 and an old Vista partition. a usb flash drive. Problems: No CD means the only boot Drive I could use is USB. There are no BIOS on Macs so I can't set boot settings or even see if it detects my USB drive. When I start the machine and press ALT the first and only thing I see is an old corrupted winXP partition and not a single option or additional information. So assuming blindly that the Mac hardware/firmware works normally, I don't have any Mac OS to use any of the tools that I found on different tutorials for building a bootable .img drive for macs. I can't find much software on Linux/Windows to substitute to those tools, for example among others converting an .iso file (win/linux) to .img (mac I guess). Which makes me think that the scenario where someone like me has Mac hardware but no Mac OS is extremely rare. So other than finding someone that has a Mac I have no solution. So I ask what would you do? the only thing is it should not involve any money (I know mac soft is rarely free) which also excludes getting any MacOS unless I can use a free macos.img for VM or restore the original Mac for free. Thank you

• Recommended Win2k8 Server software to fix my RAID-0 issue

  - by Jason Kealey

  I'm running an Asus P6T V2 Deluxe. It has six SATA ports and supports onboard RAID. I am using two of those ports for a RAID0 array of 1.5TB Seagate drives using the onboard RAID controller. One of them is giving me SMART warnings and I want to preemptively replace it. I pulled out two other 1.5TB drives from another computer and am ready to use one or both, if necessary. I can't run any SMART diagnostic software from within Windows because it only sees the hardware RAID-0 array, not each individual drive. The first thing I tried was a slow sector-by-sector copy using a free tool called EASEUS Disk Copy. Used the bootdisk, copied (took like 16 hours), unplugged the defective drive and plugged the new one in its place. The motherboard didn't recognize the new drive as being part of the known setup, so it did not want to boot. The second thing I tried was using other software (I forget the name) to copy the partition from within Windows. The first software failed because I had a server operating system. I found another software (I forget the name) which supported a server OS and did a partition copy onto the new drive. This seemed to work and the OS started to boot, but blue screened and started a reboot cycle. I'm assuming the software I was using was no good as it was trying to copy the boot disk while it was in use. I am looking for recommendations on what software to use to fix my problem without doing a re-install. Everything is backed up but my computer works fine and I'd like to avoid re-installation when possible. However, my system would be back up now if I had just started over on a second RAID array. :)

• K8NDRE motherboard in server fails to complete BIOS load with error 0078

  - by John

  K8NDRE motherboard with 4 sata drives, was running fine. Drives had raid-0 and raid-1 partitions, using mdadm. The onboard raid is disabled. Upon reformatting the drives, setting a new partition structure and new raid partitions, the bios fails to finish loading, with 0078 in the bottom right corner. Tried using completely new set of drives, and bios worked fine. Able to boot from a usb, format the drives, partition them, start raid, and then installed os. Reboot and received the same error from the bios, 0078. Works fine if I unplug the sata drives. Any thoughts? Physical inspection reveals no damage cables, connectors, or capacitors. Server was running happily for over a year, and this is the first problem it has had. Per Michael Hampton's answer: The drives, unjumpered and supporting sata III worked fine originally, and worked fine for formatting and having new partitions and raid installed on them. I did try jumpering one, with no change. If I put a brand new unformatted drive in, the motherboard recognizes it and I can proceed with formatting and installing. When I reboot, I get the 0078. I have 4 sata cables-the board supports 4 drives, so I tried each and no change. I am close to calling the motherboard done.

• Creating a partitioned raid1 array for booting a debian squeeze system

  - by gucki

  I'd like to have the following raid1 (mirror) setup: /dev/md0 consists of /dev/sda and /dev/sdb I created this raid1 device using mdadm --create --verbose /dev/md0 --auto=yes --level=1 --raid-devices=2 /dev/sda /dev/sdb This gave a warning about metadata being 1.2 and my system might not boot. I cannot use 0.9 because it restricts the size of the raid to 2TB and I assume grub shipped with latest debian (squeeze) should be able to handle metadata 1.2. So then I created the needed partitions like this: # creating new label (partition table) parted -s /dev/md0 mklabel 'msdos' # creating partitions sfdisk -uM /dev/md0 << EOF 0,4096 ,1024,S ; EOF # making root filesystem mkfs -t ext4 -L boot -m 0 /dev/md0p1 # making swap filesystem mkswap /dev/md0p2 # making data filesystem mkfs -t ext4 -L data /dev/md0p3 Then I mounted the root partition, copied a minimal debian install inside and temporary mounted /dev /proc /sys. Afer this I chrooted to the new root folder and executed: grub-install --no-floppy --recheck /dev/md0 However this fails badly with: /usr/sbin/grub-probe: error: unknown filesystem. Auto-detection of a filesystem of /dev/md0p1 failed. Please report this together with the output of "/usr/sbin/grub-probe --device-map=/boot/grub/device.map --target=fs -v /boot/grub" to I don't think it's a bug in grub (so I didn't report it yet) but a fault of mine. So I really wonder how to properly setup my raid1, everything I tried so far failed.

• file system that allow to specify different RAID level per directory and change it afterward

  - by Adam Ryczkowski

  I have 5 hard drives, where I want to keep my data. Some of my files are more important, and some of them are less. So some of them I wish to put on RAID-6, and for some it RAID-5 is sufficient. It is difficult to predict at the moment of creation of the arrays how much space of each type to declare. What I would do if I didn't hear about zfs, is partition the hard drives into identical 100GB partitions, and as my needs grow, assemble those partitions into md devices using linux-raid. Then, I'd combine those devices using lvm into logical volumes where I'd put my data. So when I'd need more space of e.g. RAID-6, I'd take 100GB partition from each hard drive and assemble them into another RAID-6 md device and would use it as physical storage for the logical volume group dedicated for RAID-6 data. Then I could grow the file system on this logical volume. On top of RAID-6 and RAID-5 Volume Groups (managed by lvm) would reside completely independent file systems, which I'd later merge with multiple mount --bind into a single directory structure that would reflect the logical structure of data rather that of the storage. But now, when I heard about the ZFS with all the performance, data-healing and compression capabilities I cannot stop thinking if it can help me. If so, what do you think would be the best setup?

• How do you recreate the System Recovery environment in Windows 7?

  - by Howiecamp

  I'm running Windows 7 Home Premium RTM (64-bit) and I want to take advantage of the system recovery tools (eg the Command Prompt) without using the Windows 7 DVD. My understanding is that this environment (WinRE) should be installed to your HDD by default as part of the Windows 7 installation. However, when I hit F8 on boot and select "Repair", I get: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem... Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. The "Info" line seems like the smoking gun. My next step was to boot from the Windows 7 DVD, and choose "Repair". It indicated my Recovery Environment wasn't on the Windows 7 boot menu (perfect) and offered to fix it. I said yes and rebooted, however same issue as above. In addition, when I booted in to Windows 7 and I looked at the boot menu options, the recovery/repair option was not there. Only my Windows installation. Finally, I ran the Disk Management tool (diskmgmt.msc) and took a look at the contents of my "System Reserved" partition (which was set to "Active" as normal). It's unclear to me what the contents should look like, however it is my understanding that the WinRE environment gets installed to this partition. (As part of the above troubleshooting I followed http://superuser.com/questions/25728/how-to-fix-windows-7-boot-process which lead to http://www.sevenforums.com/tutorials/668-system-recovery-options.html).

• Recover data from hard drive with partitions (but not most data) overwritten

  - by Macha

  I have a 500GB hard drive I've been keeping around to recover data from that I removed from a failing NAS drive that got sort of... erratic at the end. I finally got rid of the NAS when during a firmware update it removed the partition table. Fast forward to a week ago, when I was building a new PC, and a mixup resulted in me placing the hard drive in question in the new PC and installing Windows XP on the first 100GB. I'm presuming any data on that first 100GB is now gone, but for the rest of it, is there any way I can recover it at home, as professional data recovery is currently too expensive? I have a blank 1TB HDD if I can store any images of that hard drive on. The problem was definitely with the NAS and not the hard drive, as the hard drive had a successful install of Windows when mistakenly place in the new PC, and there were capacitors in the NAS's circuitry clearly broken. The data I want to recover (in order of priority) is: High: Some jpgs of family photos. Medium: Some RAW files. (There are also jpg versions of all of these) Low: Some mp3s, avis and ISOs, I can re-rip most of these if need be, but it'd be handy not to have to. (I don't need a backup lecture, and if you can hold it in from nagging Jeff Atwood for it, you can hold it in from nagging me for it) In short: The partition tables are gone and overwritten. The data is not overwritten, except for an amount equal to the size of a Windows XP SP3 installation.

• RAID degraded on Ubuntu server

  - by reano

  We're having a very weird issue at work. Our Ubuntu server has 6 drives, set up with RAID1 as follows: /dev/md0, consisting of: /dev/sda1 /dev/sdb1 /dev/md1, consisting of: /dev/sda2 /dev/sdb2 /dev/md2, consisting of: /dev/sda3 /dev/sdb3 /dev/md3, consisting of: /dev/sdc1 /dev/sdd1 /dev/md4, consisting of: /dev/sde1 /dev/sdf1 As you can see, md0, md1 and md2 all use the same 2 drives (split into 3 partitions). I also have to note that this is done via ubuntu software raid, not hardware raid. Today, the /md0 RAID1 array shows as degraded - it is missing the /dev/sdb1 drive. But since /dev/sdb1 is only a partition (and /dev/sdb2 and /dev/sdb3 are working fine), it's obviously not the drive that's gone AWOL, it seems the partition itself is missing. How is that even possible? And what could we do to fix it? My output of cat /proc/mdstat: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md1 : active raid1 sda2[0] sdb2[1] 24006528 blocks super 1.2 [2/2] [UU] md2 : active raid1 sda3[0] sdb3[1] 1441268544 blocks super 1.2 [2/2] [UU] md0 : active raid1 sda1[0] 1464710976 blocks super 1.2 [2/1] [U_] md3 : active raid1 sdd1[1] sdc1[0] 2930133824 blocks super 1.2 [2/2] [UU] md4 : active raid1 sdf2[1] sde2[0] 2929939264 blocks super 1.2 [2/2] [UU] unused devices: <none> FYI: I tried the following: mdadm /dev/md0 --add /dev/sdb1 But got this error: mdadm: add new device failed for /dev/sdb1 as 2: Invalid argument Output of mdadm --detail /dev/md0 is: /dev/md0: Version : 1.2 Creation Time : Sat Dec 29 17:09:45 2012 Raid Level : raid1 Array Size : 1464710976 (1396.86 GiB 1499.86 GB) Used Dev Size : 1464710976 (1396.86 GiB 1499.86 GB) Raid Devices : 2 Total Devices : 1 Persistence : Superblock is persistent Update Time : Thu Nov 7 15:55:07 2013 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : lia:0 (local to host lia) UUID : eb302d19:ff70c7bf:401d63af:ed042d59 Events : 26216 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 0 0 1 removed

• Using Truecrypt to secure mySQL database, any pitfalls?

  - by Saul

  The objective is to secure my database data from server theft, i.e. the server is at a business office location with normal premises lock and burglar alarm, but because the data is personal healthcare data I want to ensure that if the server was stolen the data would be unavailable as encrypted. I'm exploring installing mySQL on a mounted Truecrypt encrypted volume. It all works fine, and when I power off, or just cruelly pull the plug the encrypted drive disappears. This seems a load easier than encrypting data to the database, and I understand that if there is a security hole in the web app , or a user gets physical access to a plugged in server the data is compromised, but as a sanity check , is there any good reason not to do this? @James I'm thinking in a theft scenario, its not going to be powered down nicely and so is likely to crash any DB transactions running. But then if someone steals the server I'm going to need to rely on my off site backup anyway. @tomjedrz, its kind of all sensitive, individual personal and address details linked to medical referrals/records. Would be as bad in our field as losing credit card data, but means that almost everything in the database would need encryption... so figured better to run the whole DB in an encrypted partition. If encrypt data in the tables there's got to be a key somewhere on the server I'm presuming, which seems more of a risk if the box walks. At the moment the app is configured to drop a dump of data (weekly full and then deltas only hourly using rdiff) into a directory also on the Truecrypt disk. I have an off site box running WS_FTP Pro scheduled to connect by FTPs and synch down the backup, again into a Truecrypt mounted partition.

• Grub rescue, unknown file system. Can't boot into Windows 7

  - by Sam J

  So, I'm confused, so I'm also going to use this question to get clarification and fix my computer. So, some background: I had Windows 7 on a 1 TB HDD and decided to partition my hard drive into two ~500 GB, one for Windows 7 and one for Ubuntu or whatever flavour I desired (like a sandbox partition...) I installed Ubuntu but the installation had issues so I decided to uninstall. Note before uninstallation I had to press f12 when I turned on to boot from my primary HDD, then choose what OS I wanted to use. Undesirable, but it worked. Anyway, after I decided to uninstall Ubuntu I went into Windows 7 Start Computer Manage and deleted the EXT4 filesystem (Ubuntu parition) giving me 4xx GB of free space. However when I restarted Windows 7, I am now unable to boot Windows. When I DON'T hit f12, I see a blank screen with a flashing underscore. When I DO hit f12, I choose my primary HDD, and then I get a GRUB error: Unknown filesystem: grub rescue _ Something I'm unclear of: GRUB boots linux partitions, right? What boots Windows? Is GRUB "overwriting" the Windows bootloader? How can I completely get Windows back to normal? (IE, It boots automatically without hitting f12.) Thanks for any help, I'm on a live CD version of Ubuntu right now until I can get back on Windows.

• Microsoft Deployment Toolkit 2012 Error

  - by Jacob Schaer

  I just started with MDT2012 recently in hopes of eventually getting away with using Ghost to deploy all of our department computers. When I test deploy in VirtualBox, it deploys the OS properly, but stops because of a network driver failure (it gets the "could not allocate resources" issue). On physical hardware (Latitude E6500, Optiplex 980, and an older Latitude) it gets through the multicast and stops immediately after with: "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information" I've looked at the logs and never see anything really of note. Originally I was using DriverPacks from DriverPacks.net, but thinking it was a driver issue, I switched over to using Dell's cab driver packs. Still the same issue. I check and it did the HDD is all fine - it was properly partitioned, set to bootable, and was loaded with all the proper OS installer files. I'm using a flash drive to do the install - when I make changes to the deployment share I rebuild and copy the ISO to the drive, then use YUMI multiboot to start the ISO (probably irrelevant).

• 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.

• 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?

• Dual boot Windows 8 and Ubuntu 12.10 across a reboot

  - by AK4749

  My Setup: I have two separate SSDs, and each contains an independently bootable OS - W8 and U12.10. From my extremely limited knowledge, this means each has a functioning EFI partition(?). My default boot order (GA-Z68XP-UD3P mobo with UEFI firmware update) boots the UEFI partition containing windows first, but if I enter the BIOS I can select the "ubuntu" entry to successfully boot ubuntu. Both drives are GPT, and are EFI boots. What I want to do: Reboot Windows 8, re-enter W8 (this is happening now due to the default boot order). What I want to change, however, is to boot into Ubuntu if i reboot from ubuntu. Essentially, I would like to work within one OS unless I consciously choose otherwise. Normally, I would not even ask to something I thought was impossible, but... Why I think this is possible: When trying EasyBCD to add ubuntu to the W8 UEFI bootloader, I noticed an "iReboot" addon or something that allows you to select which OS to boot into from within the OS. Note that I ended up not using the NeoGrub entry to chain Ubuntu off the W8 bootloader because I couldn't get much help with it. Is this possible? Have I had too much coffee and gone insane? Thank you all for your time, AK

• Diff bios - corrupt video driver

  - by sfonck

  Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

• Corsair SSD appears completely blank and does not retain written data

  - by ebanders

  I have a 180GB Corsair SSD (model# CSSD-F180GB2-BRKT) as the primary drive in a Windows laptop. Recently the machine became unbootable after installing Windows updates. Windows installed updates before the machine shut down and the next time the machine boot up it complained about not being able to find a bootable device. After finding fixmbr unsuccessful at making the machine unbootable, I investigated a little within knoppix. Fdisk revealed an empty partition table. A scan by Testdisk came up empty. And finally 'head -c 1024 | hd' reveals all zeros. Creating a primary partition spanning the whole disk completes successfully, but after a reboot the disk appears empty again. dmesg reveals no read or write errors. smartctl indicates that the drive is healthy- although the SMART attribute values do not appear to be read properly. "Data Page | WARNING: PREVIOUS ATTRIBUTE HAS TWO" and "Threshold Page | INCONSISTENT IDENTITIES IN THE DATA" messages appear within the table of values. I don't have much experience with SSDs. Is this drive dead or something? Can anyone recommend any diagnostic tools that may be suited for diagnosing SSDs?

• Best format for hard drive for Windows and Mac?

  I have a 500 GB USB External Hard Drive. I need four partitions on it, for the following purposes: 160 GB for a bootable backup of my Mac. 160 GB for a bootable backup of my Windows. 11 GB for a bootable Snow Leopard Install Disk Rest as for file storage. Now I need a partition table which will get recognised on both Windows and Mac, without needing extra software on Windows, which will let me keep bootable copies of both OS'es, but let me access the file storage from both OS'es. Currently, I have a GUI Partition Table, with Mac OS Extended (Journaled) Partitions for the two backups, Mac OS Extended for the Install Disk, and NTFS for the file storage. While this gets recognised perfectly on my Mac, thanks to an NTFS for Mac driver from Paragon, when connected to Windows, the drive is detected by the machine (listed in Safely Remove USB), but not recognised in Windows Explorer unless I install MacDrive, which is not feasible for me to install on public Windows Machines I might wanna access my storage area on. Can someone recommend the best combination of formats and software/drivers to get this done seamlessly?

• Concatenating gziped Apache logs

  - by markdrayton

  We rotate and compress our Apache logs each day but it's become apparent that this isn't frequently enough. An uncompressed log is about 6G, which is getting close to filling our log partition (yep, we'll make it bigger in the future!) as well as taking a lot of time and CPU to compress each day. We have to produce a gziped log for each day for our stats processing. Obviously we could move our logs to a partition with more space but I also want to spread the compression overhead throughout the day. Using Apache's rotatelogs we can rotate and compress the log more often -- hourly, say -- but how can I concatenate all the hourly compressed logs into a running compressed log for the day, without decompressing the previous logs? I don't want to uncompress 24 hours' worth of data and recompress it because that has all the disadvantages of our current solution. Gzip doesn't seem to offer any append or concatenate option but perhaps I've missed something obvious. This question suggests straight shell concatenation "works" in that the archive can be decompressed but that gzip -l doesn't work seems a bit dodgy. Alternatively, perhaps this is still a bad way to do things. Other suggestions are welcome -- our only constraints are our relatively small log partitions and the need to provide a daily compressed log.

• I really need help resolving a Window Vista BSOD (Blue Screen Crash) on my desktop

  - by anonymous

  Hi, thanks for taking the time to read this. I'll get straight to the details. My desktop is on the fritz; it keeps going to blue screen with the stop message of 0x0000007E immediately after the loading bar of vista, right before transitioning to the account selection screen. My desktop runs on a dual-core 32-bit processor with windows Vista Home(?) installed. I have 3 GB of ram as two separate modules, a 1GB acer module and a 2GB geil module. I have an ati video card, unfortunately I cannot recall the exact name but the chipset is ATI and the manufacturer is Sapphire and the card is on the lower end. My hard drive is 320GB (i think) partitioned into two. The C:\ partition is red lined, while the D:\ partition is still pretty empty. As per the advice of my friend, i tried restarting the system with the graphics card removed. Upon failure, i repeated the process removing one RAM module one at a time, but the system still failed to load. Vista would attempt to repair the system and it would initially report that the system was fixed, but vista really failed to fix the problem. After removing the memory modules, vista started to report it's inability to fix the problem. I tried running on safe mode and the driver listing would always stop at crcdisk.sys. I ran memory diagnostics using the windows memory diagnostic tool found in the screen after vista's failed attempt to fix the problem with no luck. the problem details are as such: Problem Event Name : StartupRepairV2 Problem Signature 01: AutoFailover 02: (vista's version number?) 03: 6 04: 720907 05: 0x7e 06: 0x7e 07: 0 08: 2 09: WrpRepair 10: 0 OS Version: 6.0.6000.2.0.0.256.1 Locale ID 1033 any correct advice would be appreciated as i really need my pc to work so i can work on my projects. kinda sad, but i'm college of computer science and i have no idea what to do :P

• Hungry hungry BIOS: why do I have less than 4 GiB of memory?

  - by Rhymoid

  I thought I had 4 GiB of memory, but just to be sure, let's ask the BIOS about that: ?: sudo dmidecode --type 20 # dmidecode 2.12 SMBIOS 2.6 present. Handle 0x000B, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Physical Device Handle: 0x000A Memory Array Mapped Address Handle: 0x000E Partition Row Position: Unknown Interleave Position: Unknown Interleaved Data Depth: Unknown Handle 0x000D, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00080000000 Ending Address: 0x000FFFFFFFF Range Size: 2 GB Physical Device Handle: 0x000C Memory Array Mapped Address Handle: 0x000E Partition Row Position: Unknown Interleave Position: Unknown Interleaved Data Depth: Unknown Alright, 4 GiB it is. But I can't use all of it: ?: cat /proc/meminfo | head -n 1 MemTotal: 3913452 kB Somehow, somewhere, I lost 274 MiB. Where did 6% of my memory go? Now I know the address ranges in DMI are incorrect, because the ACPI memory map reports usable ranges well beyond the ending address of the second memory module: ?: dmesg | grep -E "BIOS-e820: .* usable" [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009e7ff] usable [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x00000000dee7bfff] usable [ 0.000000] BIOS-e820: [mem 0x0000000100000000-0x0000000117ffffff] usable I get pretty much the same info from /proc/iomem (except for the 4 kiB hole 0x000-0xFFF), which also shows that the kernel only accounts for less than 8 MiB. I guess 0x00000000-0x7FFFFFFF is indeed mapped to the first memory module, and 0x80000000-0xDFFFFFFF to part of the second memory module (a bunch of ACPI NVS things live between 0xDEE7C000 and 0xDEF30FFF, and the remaining 16-something MiB of that range are just 'reserved'). I guess the highest 0x18000000 bytes of the second memory module are mapped above the 4 GiB mark. But even then, there are two problems: 128 MiB (0x08000000 bytes, living somewhere between 0xE0000000 and 0xFFFFFFFF) are still completely unaccounted for. To note, my graphics card is on PCI-Express and (allegedly) has 1 GiB dedicated memory, so that shouldn't be the culprit. Did the BIOS screw up in moving the memory, leaving it partially shadowed by MMIO? Even with this mediocre explanation, I only 'found' 128 MiB. But /proc/meminfo is reporting a much larger deficit; where's the other 146 MiB? How does Linux count MemTotal?

• phpMyadmin issue on cpanel

  - by user1149244

  I logged in into our cpanel to view phpMyAdmin but I can't open it. It give me this error message: Warning: session_write_close() [function.session-write-close]: write failed: No space left on device (28) in /usr/local/cpanel/base/3rdparty/phpMyAdmin/index.php on line 42 Warning: session_write_close() [function.session-write-close]: Failed to write session data (files).

They just told me that the server is unmanaged. They told me to delete the free the partition but I don't know how to do it. I'm noob on that matter. The /var/log/btmp is over 8GB as they said. I want to delete that file. How would I do this? I need to free the space of the partition. I need some steps on how to do it and also steps on how to delete the /var/log/btmp. I have been googling around but I haven't found anything.
