• Migrate Windows Server 2008 to a new hard disk 2

  - by MainMa

  Hi, A few weeks ago, I already asked how to move a Windows Server 2008 to a new hard disk. Despite the previous answers and two weeks lost trying to do it, I am always unable to move the OS to the new drive. What I tried: A backup/restore using Windows Backup. This never helped. First, I tried to backup, then copy the backup to a new drive, then restore. This results in "The parameter is incorrect. (0x80070057)" error caused by a bug in Windows Backup. Recently, I attempted to backup to a network share, but I can't restore from it, because of a "*The network path was not found. (0x80070035)" error. Trying the netsh interface ipv4 set address [...] does not work neither (saw at least three different errors, mostly "The interface is unknown.") A previously suggested solution using imagex from Windows AIK results in a non-bootable disk after writing an image to it. When booting from Windows 2008 installation disk (from USB), it finds that the HDD is not bootable and proposes to fix this, but then crashes, resulting in an unbootable USB flash disk (and HDD stays unbootable). As I said in my previous question, doing a clone of a hard disk drive gives an (of course) bootable disk, but Windows complain about hardware changes and cannot start. Now can somebody suggest me another way to move Windows Server 2008 to a new hard disk? Is it at least possible to do, or any hard disk failure/change implements necessarily to reinstall the whole OS?

• Snapshotting single disk of running Hyper-V VM

  - by modelnine

  I'm currently somewhat at a loss of how to create a snapshot of a single virtual hard-disk of a running Hyper-V VM. Generally, creating a differential disk while a server is shut down is no problem (i.e., call the new-vhd cmdlet and pass a ParentPath, then update the VHD-binding of the respective VM-device), but while the host is running, all I can find is checkpointing the VM as a whole (which creates snapshots of all attached disks), and leaves the VM-state in a form which isn't easily processable by external tools (i.e., it requires reading additional meta-data from the VM). Generally, what'd I'd like to happen for a single-disk snapshot (in my understanding) is: Pause the VM Rename current disk to some other name which specifies it as a base-snapshot Create a new VHD which has the renamed VHD as parent path and is marked as "current" Swap the VHD for the VM for the snapshotted hard-disk to the newly created differential VHD Resume the VM Is there any means to do this programatically? Update: I've seen that this is actually possible with SCSI-disks, i.e. pause the VM, remove the SCSI disk, make the snapshot, reattach the SCSI disk at the same position, resume the VM. And, the VM resumes properly. But: is something similar also possible with G1 machines for the boot disk which is always IDE?

• disk write cache buffer and separate power supply

  - by HugoRune

  Windows has a setting to turn off the write-cache buffer (see image) Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. Is it feasible and economical to get such a "separate power supply" for the internal sata drives of a non-server PC? Under what name is such a power supply sold? I know that there are UPS devices that can be connected to external drives,but what is required to be able to switch this setting safely on for an internal disk? The setting has different descriptions in different version of windows Windows XP: Enable write caching on the disk This setting enables write caching in Windows to improve disk performance, but a power outage or equipment failure might result in data loss or corruption. Windows Server 2003: Enable write caching on the disk Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows Vista: Enable advanced performance Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows 7 and 8: Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. This article by Raymond Chen has some more detailed information about what the setting does.

• How to copy a floppy boot disk?

  - by Sammy

  I have a floppy boot disk and I would like to copy it to preserve it, as a backup. If I have two floppy drives, A and B, how can I copy the disk? Assuming one has two floppy drives Can I simply insert the floppy disk in one of the drives and then an empty floppy disk in the other and issue a simple command like this one. A:\>copy . b: Will this only copy the contents of the current directory and none of the files in subdirectories? Do I have to explicitly specify the option to copy everything? Also, what about the boot information? That won't get copied, right? If one has only one floppy drive... How do you copy a floppy disk if you only have one floppy drive? Do you in fact have to copy its contents to the local hard drive C and then copy that to an empty floppy disk using the same floppy drive? A:\>copy . c:\floppydisk A:\> A:\>c: C:\> C:\>copy floppydisk a: C:\> I'm guessing I will need some type of disk image tool to really copy everything on a bootable floppy disk. Something like the dd command on Linux perhaps? Am I right?

• How many guesses per second are possible against an encrypted disk? [closed]

  - by HappyDeveloper

  I understand that guesses per second depends on the hardware and the encryption algorithm, so I don't expect an absolute number as answer. For example, with an average machine you can make a lot (thousands?) of guesses per second for a hash created with a single md5 round, because md5 is fast, making brute force and dictionary attacks a real danger for most passwords. But if instead you use bcrypt with enough rounds, you can slow the attack down to 1 guess per second, for example. 1) So how does disk encryption usually work? This is how I imagine it, tell me if it is close to reality: When I enter the passphrase, it is hashed with a slow algorithm to generate a key (always the same?). Because this is slow, brute force is not a good approach to break it. Then, with the generated key, the disk is unencrypted on the fly very fast, so there is not a significant performance lose. 2) How can I test this with my own machine? I want to calculate the guesses per second my machine can make. 3) How many guesses per second are possible against an encrypted disk with the fastest PC ever so far?

• How to Find Out Who Made an ISO Disk?

  - by Qwertyfshag

  If a file is saved using Microsoft word or some other type of program, you can right click on the file to find the properties, which will indicate the computer that created the file. Is there anyway to find out who created an ISO disk image on a CD or DVD? I assume that there should be no meta data on the disk because an ISO disk image should be an exact duplicate of the original. Is my assumption correct? To illustrate with an example, let's say you found a CD at a cafe or something. You decide to look at the CD with your computer. You find out that it is an "Ubuntu live CD" that was obviously created from an ISO file. Is there any way to find out who burned the CD? Or, on the flip side, let's say you were the one that burned the "Ubuntu live CD" and you lost it. Would somebody be able to know that it was you who made the CD? Can they get any info about the maker?

• Gparted Partition Mount Points Alternate Between 2 Physical Disk Drives

  - by California Ken

  I'm running Ubuntu Server 14.04 on a system with 2 physical disk drives. I am frequently seeing mount errors on startup. When I check the drive partitions using GPARTED, I see that my two "non-system created" data partitions have the wrong disk assignments (i.e. sda1 vs sdb1) or visa-versa. If I hand edit /etc/fstab to match GPARTED, the system will boot error free one time. On the second restart I will get the "serious mount problem" error for the 2 data partitions and when I check GPARTED, the disk assignments have changed again (again, GPARTED and fstab don't match). A listing of my /etc/fstab is: /etc/fstab: static file system information. # Use 'blkid' to print the universally unique identifier for a device; this may be used with UUID= as a more robust way to name devices that works even if disks are added and removed. See fstab(5). # / was on /dev/sdb2 during installation UUID=766a06a4-e5af-484a-adf0-fa1e88da7212 / ext4 errors=remount-ro,user_xattr,acl,barrier=1 0 1 swap was on /dev/sda6 during installation UUID=8c42f835-ead3-43fb-88d8-196f5dfc3aa7 none swap sw 0 0 swap was on /dev/sdb3 during installation UUID=2214deec-ba98-47da-aea7-4e46998f3e57 none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 /dev/sda1 /media/ken/Linux-Data ext3 defaults 0 2 /dev/sda5 /media/ken/Data2 ext4 defaults 0 2 The device designations in the last 2 lines are the ones in question. The fstab entries to NOT change between system restarts but the mount points in the GPARTED display do. Does anyone have a fix for this? Thanks Mr. Young and Mr Gedak, Following is my fstab file and two blkid outputs. The fstab output is correct. The first blkid output was after a reboot and is WRONG! The sda and sdb device partition data is reversed. The 2nd blkid output was after a second reboot (fstab not changed). It shows the sda and adb partition data CORRECTLY. I didn't see any duplicate UUIDs. Does anyone have any idea why the GPARTED and blkid outputs alternate on consecutive reboots? The alternating partition data is real since when the partition assignments are reversed, the boot sequence halts with disk mounting errers (I have to press "s" to skip the mounts). Thanks again. Ken I copied the contents of a text file showing my fstab and 2 blkid outputs. The text file contents show up in the text entry box but does not appear in the main body of the question. Is there a way I can attach the text file or edit this question so that the text is displayed for question viewers?

• 7 Ways To Free Up Hard Disk Space On Windows

  - by Chris Hoffman

  Hard drives are getting larger and larger, but somehow they always seem to fill up. This is even more true if you’re using a solid-state drive (SSD), which offers much less hard drive space than traditional mechanical hard drives. If you’re hurting for hard drive space, these tricks should help you free up space for important files and programs by removing the unimportant junk cluttering up your hard disk.

• Avoid random disk names

  - by BarsMonster

  Hi! I have Ubuntu Server 10.04 1 system disk, and 5 disks in RAID-5 configuration. The problem is that names of these disks are changed from time to time, they are being randomly mixed from time to time (sda,b,c,d,e,f - so system disks might be sda, or sdc at different time for example).... is there any way to fix drive names, so that even if it's disconnected for example, no other drive can occupy this letter based on disk UUID or something?

• What free space thresholds/limits are advisable for 640 GB and 2 TB hard disk drives with ZEVO ZFS on OS X?

  - by Graham Perrin

  Assuming that free space advice for ZEVO will not differ from advice for other modern implementations of ZFS … Question Please, what percentages or amounts of free space are advisable for hard disk drives of the following sizes? 640 GB 2 TB Thoughts A standard answer for modern implementations of ZFS might be "no more than 96 percent full". However if apply that to (say) a single-disk 640 GB dataset where some of the files most commonly used (by VirtualBox) are larger than 15 GB each, then I guess that blocks for those files will become sub optimally spread across the platters with around 26 GB free. I read that in most cases, fragmentation and defragmentation should not be a concern with ZFS. Sill, I like the mental picture of most fragments of a large .vdi in reasonably close proximity to each other. (Do features of ZFS make that wish for proximity too old-fashioned?) Side note: there might arise the question of how to optimise performance after a threshold is 'broken'. If it arises, I'll keep it separate. Background On a 640 GB StoreJet Transcend (product ID 0x2329) in the past I probably went beyond an advisable threshold. Currently the largest file is around 17 GB –  – and I doubt that any .vdi or other file on this disk will grow beyond 40 GB. (Ignore the purple masses, those are bundles of 8 MB band files.) Without HFS Plus: the thresholds of twenty, ten and five percent that I associate with Mobile Time Machine file system need not apply. I currently use ZEVO Community Edition 1.1.1 with Mountain Lion, OS X 10.8.2, but I'd like answers to be not too version-specific. References, chronological order ZFS Block Allocation (Jeff Bonwick's Blog) (2006-11-04) Space Maps (Jeff Bonwick's Blog) (2007-09-13) Doubling Exchange Performance (Bizarre ! Vous avez dit Bizarre ?) (2010-03-11) … So to solve this problem, what went in 2010/Q1 software release is multifold. The most important thing is: we increased the threshold at which we switched from 'first fit' (go fast) to 'best fit' (pack tight) from 70% full to 96% full. With TB drives, each slab is at least 5GB and 4% is still 200MB plenty of space and no need to do anything radical before that. This gave us the biggest bang. Second, instead of trying to reuse the same primary slabs until it failed an allocation we decided to stop giving the primary slab this preferential threatment as soon as the biggest allocation that could be satisfied by a slab was down to 128K (metaslab_df_alloc_threshold). At that point we were ready to switch to another slab that had more free space. We also decided to reduce the SMO bonus. Before, a slab that was 50% empty was preferred over slabs that had never been used. In order to foster more write aggregation, we reduced the threshold to 33% empty. This means that a random write workload now spread to more slabs where each one will have larger amount of free space leading to more write aggregation. Finally we also saw that slab loading was contributing to lower performance and implemented a slab prefetch mechanism to reduce down time associated with that operation. The conjunction of all these changes lead to 50% improved OLTP and 70% reduced variability from run to run … OLTP Improvements in Sun Storage 7000 2010.Q1 (Performance Profiles) (2010-03-11) Alasdair on Everything » ZFS runs really slowly when free disk usage goes above 80% (2010-07-18) where commentary includes: … OpenSolaris has changed this in onnv revision 11146 … [CFT] Improved ZFS metaslab code (faster write speed) (2010-08-22)

• Cleanup vs Dispose(bool) in MVVM-light

  - by Budda

  In the lastest version of MVVM-light (V3 SP1) both "Dispose()" and "Dipose(bool)" methods in ViewModel class are marked Do not use this method anymore, it will be removed in a future version. Use ICleanup.Cleanup() instead Does this mean that IDisposable interface must not be implemented in all ViewModel classes that are derived from GalaSoft.MvvmLight.ViewModelBase (and cleanup must be overrided)? If yes, using can't be used for view-model instances... Probably I didn't understand something... Please clarify... What are the benefits of such cleaning up? Thanks.

• Moving Windows XP from ICH10R RAID 5 to single disk using Linux [migrated]

  - by tudor

  A friend's machine running Windows XP refused to boot recently which is running 3 SATA disks on RAID 5 (which was previously upgraded from RAID 1 not by me). I have determined there to be a disk failure. The disks have been replaced many times in the past few years. I wish to backup the RAID5 partition before I try anything to fix it. The RAID chipset used is ICH10R/DO. So, I plugged in an extra IDE drive and an Ubuntu USB key and looked at the RAID. The partitioning is a mess, but I did find at least one degraded but working RAID array with two partitions, one 79GB and the other 86GB. Then I: 1) Partitioned my IDE disk using fdisk to have a partition of 80GB and bootable, and marked as NTFS. 2) dd the contents of the array to the partition 3) disconnected everything else 4) inserted a Windows XP CD and ran fixboot, fixmbr, and bootcfg. They all run ok and claim that they worked. (e.g. bootcfg detects the Windows partition, fixboot returns saying that it was written correctly.) However, I'm still getting an error like "DISK FAILURE, BOOT DISK NOT FOUND". I have tried running the GRUB rescue disk, which also runs ok, but won't boot into Windows. It just stops with a flashing cursor after chainloader +1, boot. One clue may be that the partitions appear to be wack. One disk has a 79GB RAID partition on a 500GB drive with a offset, the second disk has a 320GB RAID partition across the whole drive. Additionally, the BIOS lists the RAID size as being 149GB. I don't see how this works. How are they even assembling the array when the partitions are so different? I have also tried running the Windows XP automated repair tool, but that didn't work either. I'm presuming this is something simple. Perhaps Windows is attempting to boot into RAID and, upon not finding it, simply crashing? Perhaps the 79GB partitions offset means that it's looking into the disk by that much? Please help!! To clarify: I want to make the single IDE disk bootable with a copy of the array so that I can prove/disprove that it's just that Windows has become corrupted, and use windows tools to correct it before attempting the same thing on the RAID array. That way I have a working backup and can show the process I used to fix it.

• Can't connect disk management to remote XP PC from local Win7/Server 2008

  - by Grez

  Scenario as follows: support technicians using Windows 7 PC's or Server 2008 terminal server are unable to connect Disk Management MMC snap in to a remote PC when the remote device is running Windows XP. "Disk management could not start Virtual Disk Service (VDS) on ". This can happen if the remote computer does not support VDS, or if a connection cannot be established because it was blocked by Windows Firewall." Connecting from another XP machine or 2003 server to the same XP machines works fine. Even connecting from XP/2003 to the Win7 or 2008 server works fine. Windows firewall disabled on all devices. I'm guessing this is something to do with the fact that XP uses logical disk manager service whereas Win7/2008 use Virtual disk manager service. But there doesn't seem to be any way to use logical disk manager service from 7/2008 to connect to XP...

  I have formatted Canyon CN-MP4A USB flash drive with Disk Utility on Mac and now it is not recognized on any Mac or Windows machine. I have formatted with Disk Utility > drive > Erease > Format > MS-DOS (FAT). Now when I plug it in any Mac or Windows machine, nothing happens. Like nothing is plugged in. It has a screen, and I was able to format it directly from the device before, but now when I turn it on, welcome screen appears, but nothing else. I can not get to the menu. Is there a way I can format it? I am looking for the answer on the internet, but no luck so far.

• Is it reasonable that a random disk seek & read costs ~16ms?

  - by fzhang

  I am frustrated about the latency of random reading from a non-ssd disk. Based on results from following test program, it speeds ~16 ms for a random read of just 512 bytes without help of os cache. I tried changing 512 to larger values, such as 25k, and the latency did not increase as much. I guess it is because the disk seek dominates the time. I understand that random reading is inherently slow, but just want to be sure that ~16ms is reasonable, even for non-ssd disk. #include <sys/stat.h> #include <sys/time.h> #include <sys/types.h> #include <sys/unistd.h> #include <fcntl.h> #include <limits.h> #include <stdio.h> #include <string.h> int main(int argc, char** argv) { int fd = open(argv[1], O_RDONLY); if (fd < 0) { fprintf(stderr, "Failed open %s\n", argv[1]); return -1; } const size_t count = 512; const off_t offset = 25990611 / 2; char buffer[count] = { '\0' }; struct timeval start_time; gettimeofday(&start_time, NULL); off_t ret = lseek(fd, offset, SEEK_SET); if (ret != offset) { perror("lseek error"); close(fd); return -1; } ret = read(fd, buffer, count); if (ret != count) { fprintf(stderr, "Failed reading all: %ld\n", ret); close(fd); return -1; } struct timeval end_time; gettimeofday(&end_time, NULL); printf("tv_sec: %ld, tv_usec: %ld\n", end_time.tv_sec - start_time.tv_sec, end_time.tv_usec - start_time.tv_usec); close(fd); return 0; }

• IOMEGA 500GB hard disk data reccovery

  - by Vineeth

  Last year by November I bought an IOMEGA 500GB Prestige hard disk. Yesterday, unfortunately the hard disk fell down from my table. After that incident, when I connect my disk, Windows asks me to format the disk to use, but I didn't format it yet. Actually, on that hard disk I have about 320GB of data. I tried all my possible ways to access my disk. I tried using DOS. It shows "data error (Cyclic redundancy check)". I have a 3 year warranty. Will I be covered under warranty if I report this issue to IOMEGA? Can I get my data back?

• Solaris disk I/O spike... which monitoring tools do I need?

  - by bonez05

  Hi all, My Solaris 10 websever / database server disk io keeps spiking at intermittent times. Using iostat -xtc 5 the reads / sec will jump from 3.0 to 1450.0 and %busy will jump to 98% The apache access log doesn't indicate anything out of the ordinary. In other words, requests aren't any higher than usual. top doesn't generate anything useful. The cpu usage is fine with mysql using about 20% and nothing else to speak of really. What monitoring tool should I be using to see what process is using excessive disk I/O? or if there are any other suggestions I'm all ears. Thanks

• Volume size doesn't match Disk size after gparted expansion

  - by Cybersylum

  I just expanded a basic disk on a Windows XP VM from 15gb to 40 gb using GPARTED LiveCD (0.5.2-11). I didn't notice anything unusual during the expansion; but after I rebooted back into Windows, the disk capacity doesn't match the disk size as it should (only 1 volume on the disk). The disk shows as 40gb; but the C: volume still shows the original size. I've tried expanding the disk again with GPARTED (no change), and using VMware converter and have it adjust the size of the volume during the process (complains about a lack of space of snapshot error inside the os). The volume has 27% free space so I don't think it is a space issue. Chkdsk doesn't seem to find anything wrong either. The OS seems to run just fine, it doesn't see the additional space however. Any ideas?

• Dell 2950 Perc 6/i "physical disk" and "Enclosure(Backplane)" under Connector 1 in OMSA tree- Troubleshoot help

  - by user66357

  Just looking for someone who might know why this could occur... In OMSA, on my Dell 2950, there usually is only one "Physical Disks" child under "Enclosure (Backplane)" in the tree view. Currently, the tree looks like this: Dell PERC 6/i Integrated Connector 1 (RAID) Enclosure (Backplane) Physical Disks (1:04 good, 1:05 removed) Physical Disks (1:33 Ready but unused) Normally it's like this: Connector 1 (RAID) Enclosure (Backplane) Physical Disks (1:04 good, 1:05 good) From the front, 6 of 6 3.5" SAS drives are connected. The server is showing Slot 5 as bad and the disk as removed. It seems that the drive in Slot 5 is being sensed as external to the Enclosure. Any ideas why this would happen? Think I can get away with rebuilding the virtual disk by replacing 1:05 with 1:33? Thanks.

• Can I "branch" VirtualBox snapshots (base multiple VM on the same disk image + separate diffs)?

  - by Thilo

  I keep multiple VirtualBoxes for different projects. They are all running the same Debian base system. Keeping complete copies of all the disk images is getting expensive. Is there a way that I can base multiple VM on the same (read-only) disk image, with (hopefully small) diffs layered on top? This is just like snapshots work, except that there is no concept of "current" and "previous", they are more like branches. Or can I just use snapshots (of the "same" VM) for this? I would be wanting to run more than one of those snapshots concurrently.

• 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.

• grub2 error: out of disk

  I'm trying to make a 250G USB hard disk Ubuntu-bootable on a Compaq nc6220 laptop. I've removed all other disks, so /dev/sda (the USB disk) is the only disk other than CDROM. I installed Ubuntu 9.10 to this disk from the live CD, putting the bootloader on /dev/sda . The default system couldn't be booted, and nothing I did in the Grub menu/cmdline helped. So I chrooted onto the disk and did grub-install /dev/sda. That seemed to work fine, but Grub (1.97 beta 4) keeps coming up with error: out of disk Even when I drop to the command line to do something simple like ls or help, it's always the same error message. Any hints for resolving this, please?
