  • How can I recover XFS partitions from a formatted HD?

    - by giuprivite
    I deleted the partition table of my HD. I wanted to format another one, but by mistake, I formatted the wrong one. Then I also created some new partition on it. Now I would like, if possible, to recover my old data. The old configuration was this: A primary NTFS partition with Windows, and a secondary partition with four logical partitions: a swap and three XFS partitions (two for Ubuntu and OpenSuSE, and one with the home for both systems). This is the output I get when I run gpart in a terminal: ubuntu@ubuntu:~$ sudo gpart /dev/sdb Begin scan... Possible partition(Windows NT/W2K FS), size(39997mb), offset(0mb) Possible extended partition at offset(39997mb) Possible partition(Linux swap), size(8189mb), offset(39997mb) Possible partition(SGI XFS filesystem), size(40942mb), offset(48187mb) Possible partition(SGI XFS filesystem), size(40942mb), offset(89149mb) Possible partition(SGI XFS filesystem), size(175044mb), offset(130112mb) End scan. Checking partitions... Partition(OS/2 HPFS, NTFS, QNX or Advanced UNIX): primary Partition(Linux swap or Solaris/x86): logical Partition(Linux ext2 filesystem): logical Partition(Linux ext2 filesystem): orphaned logical Partition(Linux ext2 filesystem): orphaned logical Ok. Guessed primary partition table: Primary partition(1) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 39997mb #s(81915360) s(63-81915422) chs: (0/1/1)-(1023/254/63)d (0/1/1)-(5098/254/51)r Primary partition(2) type: 015(0x0F)(Extended DOS, LBA) size: 265245mb #s(543221849) s(81915435-625137283) chs: (1023/254/63)-(1023/254/63)d (5099/0/1)-(38912/254/2)r Primary partition(3) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Primary partition(4) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Looking the first eight lines, it seems the data are still there... but I don't know how to recover them. I have a free second HD of about 500 GB (the formatted one is 320 GB) that I can use for the recovery process.

  • Linux WD30EZRX WD Green HDD & Blacx Duet 5G Usb

    - by Adam
    I have connected up an WD30EZRX WD Green HDD to a Thermaltake Blacx Duet 5G USB dock in Ubuntu 12.04. Every thing seems fine except when the HDD idles it seems to have error ls: reading directory .: Input/output error after a while and is only fixed by unmounting and remounting the drive as root. I have the following line in /etc/fstab UUID=AAF670E9F670B6E3 /media/3TB ntfs defaults,user,auto 0 0 I have noticed that it seems to go between /dev/sdc2 and /dev/sdd2 devices on remount. I did copy 1TB last night without issue in 1 sitting. But after x mins of idle it has remount issue. Any tips/suggestions on how to proceed would be appreciated. Spent most of the night googling and all its done is made me sad. Edit (tried as suggested): root@mediaserver:/media/3TB# sudo hdparm -B 255 -S 253 /dev/sdd2 /dev/sdd2: setting Advanced Power Management level to disabled HDIO_DRIVE_CMD failed: Input/output error setting standby to 253 (vendor-specific) APM_level = not supported Seems as if that didn't help with this particular drive.

  • Using a non-validated SED on a Dell R720

    - by a coder
    We were given a Dell R720 a couple years ago, and the machine currently has standard 300GB 3.5" SAS 15k drives. Our RAID controller is a Perc H710. We need to update our disks to FIPS 140-2 certified SED. According to Dell, they have only one tested/validated FIPS SED for this machine/controller, but it is a 7200rpm 3.5" unit. I'm showing that Dell offers a 600GB 15k FIPS SED in 3.5" configuration (Dell part number 342-0605), but they say they haven't validated or tested to know if it works. They informed us that we would not void our warranty in using this non-validated drive. How likely is it that our R720 with H710 controller will work with the non-validated drive? Are there significant differences in how drive manufacturers build SED that would prevent them from working consistently across different controllers?

  • Bluescreen Stop 0x00000027 RDR_FILE_SYSTEM after cloning system on new HDD

    - by Daniel
    A couple of months ago I got a new 500GB HDD for my no-name-brand Laptop PC and I cloned the complete Win 7 Pro 32bit system with clonezilla from the old 70GB drive to the new one. At first everything was great, the new driver was immediately updated. But since then I get on a more and more frequent level (used to be every 2-3 days, but now it's more like 2-3 times a day) a BSOD Stop error. From the eventlog in Windows I know that there are two different error codes sppoking aroung: 0x00000027 (0xbaad0073, 0x9954f80c, 0x9954f3f0, 0x8ecd7c82) RDR_FILE_SYSTEM 0x00000044 (0x85443230, 0x00000eae, 0x00000000, 0x00000000) MULTIPLE_IRP_COMPLETE_REQUESTS I checked for viruses and did a complete HDD check using the Windows tool and WesternDigital tool (which is the producer of the new HDD) without results. I also looked for driver updates but couldn't find any. The name of the HDD as shown in the device manager is: WDC WD5000BPVT-00HXZT1 ATA Device. I'm really a noob regarding those kind of problems, so if you have any idea what I can try without losing all my data, let me know. Also, if any additional information are required.

  • is a mini PCIe SSD worth it?

    - by Narcolapser
    Question: Is getting a mini-PCIe worth investing in? Info: I have a an Acer Aspire 1 n270. It has this mini PCIe slot that is just sitting there empty. I would like to change this, and I would like to speed up my boot time. So I've been considering getting a mini-PCIe SSD. They are about the same price as faster same size drives of the 2.5" variation. The advantage of the mini-PCIe card is that I can have my HDD still. So I have good boot time, but still have the storage of my HDD. What I want to know is: will this allow me to spin down the HDD more often allowing me to save power? Will the OS (Ubuntu 10.04 LTS) see them as separate drives? Is there anything that the mini-PCIe slot could be better used for? Thanks. ~n

  • Does the advanced format tool bundled by manufacturers actually do anything which mkntfs doesn't?

    - by neurolysis
    I recently bought a new drive (specifically, a 2TB Samsung Spinpoint) that says on the label that it supports advanced format, and that I should download the tool from their site. Unless I'm missing something, mkntfs has always had its maximum sector size at 4096b: -s, --sector-size BYTES Specify the size of sectors in bytes. Valid sector size values are 256, 512, 1024, 2048 and 4096 bytes per sector. If omitted, mkntfs attempts to determine the sector-size automatically and if that fails a default of 512 bytes per sector is used. Will this tool on Samsung's site do anything other than format the drive in the same way doing mkntfs -s 4K /dev/sdb1 would do? To be specific, I'm intending to use this drive on a machine that will primarily run Windows XP, but I'd rather boot into Linux/BSD and format the disk manually than have bloated software. I do want to have the new AF style sectors though -- that's essential. So if I did the command above, would it have exactly the same effect as using the advanced format tool?

  • Is it possible that solid state drives (or any faster drive) will make common applications faster even if they are cached?

    - by leladax
    I assumed that solid state drives are insignificant after, say, Firefox is fully brought up and no important disk activity after that is going on. However, I wonder if some kind of 'cached from the disk to the CPU' activity is going on that may make solid state drives (or any faster drive) better. Then again, I suspect that may be depended only on the Bus (or some kind of cache memory drives have). Hrm..

  • Drive Shows No Files But Half Space Gone

    - by Chance Robertson
    I have a 500 GB USB drive. When I go to Windows Explorer or Finder, the drive shows that about half the drive is free. However, when I open either drive in Windows 7 or OS X, no files how up. I have tried to look at the files through the command line and nothing shows. A while back, I hooked it up to my MacBookPro and there was a quick message that said the drive was not ejected properly, blah, blah. And of course I did not read the message and hit OK. It there any way to get back my files from the drive?

  • How hard for a Software Developer to Maintain a Server

    - by Samy
    I'm a software developer and don't have much experience as a sysadmin. I developed a web app and was considering buying a server and hosting the web app on it. Is this a huge undertaking for a web developer? What's the level of difficulty of maintaining a server and keeping up with the latest security patches and all that kind of fun stuff. I'm a single user, and not planning to sell the service to others. Can someone also recommend an OS for my case, and maybe some good learning resources that's concise and not too overwhelming.

    - by Nrew
    Details: BIOS: AMI Bios, set primary master to Auto OS: Windows XP Sp2 Memory: 384 Mb Processor: Pentium 3 yeah this one is really very old. And some of the capacitors in the motherboard are already bulging. It detected the hdd yesterday when were trying to fix it and install xp. But today it cannot boot and said: Boot failure. What can you suggest that I would do to revive this old machine. What would be the problem, is it the hdd, the ide cable or the motherboard.

  • HD latency measurement using bonnie++ on different machines with different RAM size

    - by j0nes
    Hello, I have run bonnie++ v1.96 on two different servers without any additional load. One server is a "physical" Dell server with 32GB RAM, the other one is a virtual instance with 14GB RAM. I have read in the bonnie manuals that I should use two times the size of RAM in my bonnie runs, so I used 64GB on the physical machine and 28GB on the virtual machine. Now I want to compare the results, and I am wondering whether the results are comparable at all. The most interesting part is the latency part - on the physical machine, the values are about 10 times higher than on the virtual machine! Can I take these results seriously (e.g. the virtual machine HD is much much faster) or does the different RAM size tamper the results? Thanks! Jonas

  • Intel ICH9/10R raid 5 drive failure

    - by davpen
    About a year ago I was using the native Intel ICH9R Raid 5 an Intel P35 based motherboard. The system was running Vista x64 and when one of the drives failed Vista blue screened on boot until I had figured out which drive had failed and removed it (a rather nerve racking hit and miss affair). The same thing happened some months later on another similar system so it wasn't a once off. This wasn't the robust raid 5 drive failure behavior that I would have hoped for and expected. I moved to Highpoint Rocketraid 2300 and haven't had any problems although I have yet to have a drive fail with this set up. But I am now looking to build a new system based on an i7 and Windows 7. At the moment Highpoint doesn't have drivers for Windows 7 so I am considering moving back to the on board Intel Raid. Yes I know I that I might get away with using the Vista drivers but I don't really want to take that chance with critical data. The question then is has anyone else experienced a drive failure with Intel raid and how did the OS and drivers handle it? Is it safe to go back?

  • diagnose "corrupt file" problems

    - by Matthew
    My computer has been crashing the last couple weeks pretty regularly (at least once a day). A lot of times things I do will display a little notification in the bottom right saying something about a corrupt file. (I'm on Windows XP Pro Service Pack 3). When the computer does crash I get the "blue screen of death" usually. Some of the notifications also advise running the chkdsk utility. I cannot get it to successfully run. Using the command prompt (or even the "tools" menu after right clicking the drive and choosing properties), it will not run the utility (it says "do you want to schedule it to run next boot time" or whatever, which I confirm). The problem is that most of the time after restarting, it doesn't run at all. The few times it does run, it has an error (I can't remember the error right now, it at least says it's ntfs and such) and says disk checking will end. How can I get it to successfully run?

  • Strange performance from RAID5 using WD RE4 disks

    - by Howard
    I've noticed a bit of a performance issue with some WD RE4 drives I'm using under AMD's hardware RAID solution. First a bit of background: Environment: Windows 7 home premium x64 HDD's: 3x 1TB WD Raid Edition 4 in a RAID 5 setup with 128 kbyte stripe (2TB usable space) Testing Tool: HD Tune, process set to "High Priority" Processor: AMD Phenom II x6 1100T Ram: 16GB DDR3/1600mhz Motherboard: MSI 970A-G45 The image below pretty much depicts the issue I'm having. Every test has the same thing, a period of similar length where the performance drops to a few megabytes a second. This can't be a TLER issue as the purpose of RE4's is to work around that. Any help would be greatly appreciated.

  • Does WD Drive Lock encrypt the data?

    - by ssg
    I wonder if WD Drive Lock ineed encrypts the data on a Western Digital My Book Essential device or just puts a firmware-level password on the device. If it's just a password the data surely could be retrieved by a third party. I could not find anything on about that on user manuals. I found a blog saying "data is secured with AES256" bla bla but that doesn't say anything about if the password could be compromised or not. Because I don't see any delays when I add/remove the password. On the other hand when I enable BitLocker, it takes hours before it encrypts everything with my password.

  • Which HDD brand do you ..trust

    - by Shiki
    Okay it says its 'subjective' but I believe it's not. Basically I want to ask the community about your preference. Not really 'preference' but actual experience. Like if you never had a problem with Western Digital, then write that in an answer, or if there is one with WD, just vote it up. And so on. (Heard so many stories, experiences. I only had Samsung, Maxtor, WD, Seagate HDDs. Samsung died with bad blocks, had anomalies. Maxtor died so fast I couldn't even try it really and it's really hot, loud. Seagate is just as loud as a jet plane, and moderately hot. My WD (green) is quiet, really cool and somewhat fast. That's all I have about experiences. So I would say Western Digital in an answer (OR Hitachi. Never had one yet, but every expert I know says I should get one since they even had problems with WD but Hitachi seems to be ok. (My laptop comes with Hitachi hdd but I don't think its really relevant.)) Basically I mean desktop 7200RPM HDDs here. Well.. notebook HDDs are ok also, but no raptor/scsi/server ones. Hope you get what I meant and it won't get closed.

  • Partition table correpted in windows 7 machine as simple dynamic partition

    - by raki
    I have Windows 7 installed in my system. When I originally partitioned it I made 3 partitions and 16 gb space as unallocated. Later I tried to create a partition using this free space using diskmanagement tool. It shows free space as unusabe space and the only one option available is to make it as a simple partition. Unfortunately I made it as simple partition and all my partitions converted to simple dynamic partition. Now after reboot the OS is not loading. I tried to reinstall the OS by formatting the C drive, but it doesn't work. Now I can't load the OS properly. How can I install Windows 7 on my system without losing my data on the other two drives?

  • Can't initialize drive in Windows 7

    - by Abe
    I have a 2.5" laptop harddrive that I plugged into my laptop through a SATA to USB cable. It's powered by an adapter to a normal wall-plug. I want to use it as an external harddrive. It wouldn't initialize (Device is not ready), so as suggested in some instructions I found I uninstalled the drivers, unplugged it and plugged it back in. That worked, and I initialized the drive and formatted it. However I unplugged it after that and a few days later the same strategy does not work and I can't figure out how to use the drive. I can't initialize it and it doesn't show up in my computer.

  • Is it possible create a 4TB bootable partition in the x86 edition of Windows Server 2003 Enterprise?

    - by Giffyguy
    I'd like to find out if there is any way to accomplish this, since it would benifit my storage server greatly. I am using a Promise FastTrak 8660 and five Seagate ST31000340NS 1TB drives in a RAID 5 array. I figure that if the x86 ENTERPRISE edition of Server 2003 can handle 64GB of RAM, it should have no problem supporting larger HDD volumes as well. I've read (somewhere...) that the Windows Server operating systems are not limited to the standard 2TB like Windows XP and 2000 are. I'm hoping it's something that just needs to be turned on, similar to the way PAE works for the 4GB RAM limit in x86 servers.

  • Harddrive in the freezer ever work for you?

    - by Stefan Thyberg
    Once upon a time, my little 10 GB drive in my webserver failed and of course I had no backup, teaching me to immediately set up an automatic backup job afterwards. Anyhow, this drive refused to start and as a last-ditch effort I put it in a plastic bag and put it in the freezer overnight, since I had heard somewhere that it might work and I really didn't have any other options. The next day I take it out, immediately plug it in outside the case and lo and behold, the drive works long enough for me to copy my data off it. Have you ever had a similar experience with this method?
