External Hard Drive won't initiallise due to Cyclic Redundancy Check Error - Please help.

    Question

  • A few months ago I purchased an external Buffallo Drive Station with Turbo USB (HD CEU2 - 500GB). It installed perfectly fine on Vista and I was able to transfer all my music onto the larger drive (freeing up much needed space on my laptop). Every thing was fine until recently when I plugged in the hard drive and it did not appear. After various attemtps to plug back in, reinstall drivers Turbo USB etc I checked the Disk MAnagement and I could see the drive but it was not initialized. So I tried to get the disk to inititialize but I got the Cyclic Redundancy Error Check. I have tried various programs to check the drive for bad sectors but the problem when even booting it directly from floppy (inc the drivers for the USB ports) the disk is not recongised as being there. The only two places it appears when it is plugged in is the dik management and in devices.

    I don't know if this is important but my cat at one point knocked the drive over onto a hard surface a few days prior to the problem.

    I really don't want to lose the hours spent riping all my CD's on to the drive. :(

    Please does anyone have any suggestions as to how I can eith fix this or at the very least get me to the point where I can transfer all my data off the drive onto another?

    Thank you very much

  • Hi,

     

    Thanks for posting in Microsoft TechNet Forum.

     

    Based on my research, Cyclic Redundancy Check (CRC) is bit of mathematics used to ensure that your data is OK when being transfered. It's a checking procedure that quickly identifies when data has been damaged. If you get this message, it means that the file being read by your PC or software is corrupted. However, it does not mean all the data is lost forever. When data is transferred, it is usually in small blocks and each block is given a CRC value. If something goes wrong with the data between the time it leaves the source and arrives at its destination, the CRC sent at the source will no longer match the one that is calculated when the data arrives - this is when the Cyclic Redundancy Check error will appear.

     

    To troubleshoot this kind of issue, let's perform the following steps.

     

    1.    Use a command line to relocate the disk.

     

    1)     Open Command Prompt.

    2)     Type: diskpart.

    3)     At the DISKPART prompt, type: rescan.

    4)     Try to initialize disk.

     

    2.    Running Disk Utilities to check disk error, here I provide CHKDSK utility.

     

    1)     Open Command Prompt.

    2)     Type: chkdsk /f.

    3)    After checking disk error, retry the command: diskpart

     

    If the issue persists, please continue the step.

     

    3.    Use Windows PE to copy the CD files out of this disk, then use CDCheck to recover CD files.

     

    You can download Windows PE in the following website.

     

    http://www.microsoft.com/downloads/details.aspx?FamilyID=c7d4bc6d-15f3-4284-9123-679830d629f2&DisplayLang=en

     

    Then, boot in Windows PE to copy CD files out of the disk.

    If you can't access disk neither in Windows PE, I recommend that you contact hardware manufacturer for fix.

    Otherwise, if you can access disk, please copy CD files out of disk. If the CDs are damaged, you can use CDCheck 3 to recover this files. It's free for personal use. You can obtain it in the website as follow.

  • I just wanted to take the opportunity to thank you. I have not had the time to try your suggestions yet but really appreciate your helpful suggestions. I will try to report back after i have had the chance to put them into action. Thanks again

  • I'd also like to piggy back on this issue.

    My Laptop was running Windows XP and was starting to cause me all sorts of issues. After which I bought the Buffalo HDCE2 and transferred all of my files onto the external drive. My laptop subsequently died - but not a problem, all of my files were on the Buffalo drive - result! No.

    I bought a new Vista Laptop (HP HDX 18) and plugged in the Buffalo drive.

    The external drive was plugged in and fell onto it's side but appeared to be in good working order although it made a bit of a grumbling noise to start with.

    I can see the drive in the device manager but it does not show up in Explorer.

    So I have tried the following based on PCW in store help and the Buffalo tech support team help (who basically stated they did not have a solution to this - suggested I use UFS but this does not work as the drive is not recognised as it is not initializing).

    1. Open disk management (Right click my computer, manger, disk management snap in). Initialize disk - failed.

    2. Cracked open the case (data is more important than a £60 drive). Inserted the drive (Western Digital WD5000AKS - WD Caviar) into an Akasa e/SATA caddy.

    i) Used eSATA connection - device manager did not find the drive.
    ii) Used USB connection - device manger can now recognise the drive.

    3. Back to disk management==>

    Disk initialize - Failed.

    4. So I'm now into the realms of support forums and web searches.

    I have tried to initialize the disk - no success.

    Q. How can I do this in diskpart?? I do not see a command for /initialize - or do you mean re-try in Disk Management (DM).

    I tried in DM but it still fails. I cannot run chkdsk /r as the volume is not available so no drive letter is available....

    BUFFALO External HDD USB Device
    Disk ID: 00000000
    Type   : USB
    Bus    : 0
    Target : 0
    LUN ID : 0
    Read-only  : No
    Boot Disk  : No
    Pagefile Disk  : No
    Hibernation File Disk  : No
    Crashdump Disk  : No

    There are no volumes.

    5. DM - You must initailaize the disk (MBR or GPT).

    Select GPT (??) - The system cannot find the file specified

    Select MBR (??) - The system cannot find the file specified

    6. Also - I get Cyclic Redundancy error but I can't use any 3rd party software as it doesn't allow it on disk 2 you need to assign a drive......which you can't do in diskpart unless it has a volume, and I can't add a volume.

    7.
    Additional info:
    Data approximately 200 GB
    Running DISKPART as Administrator

    Please help, the data on this disk is my only backup of the data that was lost on the old laptop.

    Backup backup backup - didn't realise it meant create 3 copies!!!

    Attempting Windows PE boot now but I don't see how I can copy data off the drive if it isn't initialized....

  • I have also run the WINPE option and this has not helped initialize the disk.

    If I add the USB 2.0 device and rescan the hdd is located. I can select it as disk 2.

    However, if I rescan the hdd is lost! Therefore I cannot do anything with this disk now!!!

    A response would be greatly appreciated.

  • exact same problem here, hopefully we get a response

  • Having the same issue. I noticed the thing we all have in common with this issue is USB or some type of external configuration...

  • Well unfortunately I gave up the ghost on this issue and ended up taking my drive to a hard disk repair shop. "They" told me that the hard disk was damaged and that I needed to get some parts replaced - luckily, the data was all intact so I have recovered everything I needed. Now I have two WD drives that I backup in unison with my laptop! A hefty and time consuming way to protect data, but better than the hassle of all this again!

    Good luck to you all.

    PS I also used a SATA connection cradle and this didn't even find the drive in disk manager - at least when I used teh USB it showed up (albeit that if yu refresh you'll notice that it disappears again!!)
    Monday, October 26, 2009 11:07 PM
  • Exactly same problem that I have!
    Maybe some special software is needed to recovery the partition.
    Do you have any to suggest?
    I do not want to bring to any disk repair shop. Just don't trust that it will be safely recovered.

  • I have the same problem as u described.

  • I had the same issue.

    I downloaded the full version of easeus data recovery wizard and was able to retrieve 95% of my data. I guess I'll have to buy a new HDD, since it's most likely destroyed mechanically from a shock.

    Good luck.
