Thread: Adding/Mounting New Drive & Recovering Corrupt Data

    Default Adding/Mounting New Drive & Recovering Corrupt Data

    Hoping somebody can help me with a problem.

    I have a Hard Drive that has a corrupted file system and i have tried the usual MS Windows fixes, chkdsk and a number of recovery tools inc Dos recovery tools and failed.

    The Drive is an MS Windows drive with an NTFS file system.

    chkdsk scans and after several hours fixing numerous problems eventually gives up and fails to complete.

    The directory "My Documents" contains several GB of data and displays that this is true. When trying to access the directory, access is denied because its corrupt. Using Windows and Dos recovery tools i can view the contents of the directory sometimes! but cannot copy out any of the data, the applications return messages saying no can do basically.

    I would like to try to use Linux to recover the data.

    Problem number one is i have never tried to add a hard drive to an existing Linux system before, how do i go about adding a new drive?

    The 2nd problem is, is there a Linux application that i can use to attempt to repair and recover the corrupt data on this drive or more specifically in the "My Documents" directory.

    You already have a Linux system running on another machine? What flavor/ version?

    If so you just hook up the drive then mount the partition on the old drive.

    You could also boot to a cd distro and try the recovery from there. Maybe trying to copy the files to a removable device.

    Thank you for your reply.

    The Linux Box is running SuSE Linux 64bit 11.2

    How do i mount an added Hard Drive? Never done this before.

    How do i recover / repair the corrupt data on the added drive? Never done this before on a Linux OS.

    What should i download and burn to disc to give me a virtual Linux environment. Will it contain the applications i will need to repair the corrupt data.

    I have tried Avira's RescueCD which is a Linux solution, it mounts the drive and tells me the directory "My Documents" exists and is large in size. When try changing into the directory i succeed but if i offer the command to display the contents of the directory its empty. But it isn't, its just corrupt, so i need to run a Linux app to repair the corrupt contents of the directory before i can recover the contents.

    Avira's RescueCD doesn't contain the apps i need to repair corrupt data or so Avira tell me.

    my free advice:

    data recovery is not for the faint of heart...if the data is valuable
    send the drive to a recovery expert...along with a BIG box of money
    (and a note with a promise to set up the successful helper with your
    drop dead beautiful sister)..

    every other move you make with that drive could cause it to become
    completely inaccessible, even by an expert..

    the problem (actually not _the_ problem but one problem) is that the
    data IS corrupt....do we know why or how it got corrupted? it could
    easily (and probably is) a hardware problem....no program can safely
    "repair" the corrupt contents of the disk without *writing* TO the disk..

    but, any attempt to write to the disk could easily OVER WRITE good,
    non-corrupted data on the disk..

    so do NOT write anything to that disk....unless you want all the data
    on it destroyed, maybe..

    in fact, if it were my disk i would mount it READ ONLY...(and, i've
    done this before)...once mounted read only then you can NOT repair the
    data on that disk...you can only READ it to a different disk....where
    *maybe* you can slowly, find the different chunks of usable data and
    stitch back together the readable bits..

    most likely there WILL be data loss already...other wise it wouldn't
    be corrupt..

    that is my two cents..again..

    The data i want to repair and recover can be seen using an MS Dos application so it's still there for repair and recovery......i hope!

    In such cases in the past i have always been able to repair and then copy out data using an MS windows or MS Dos application.

    Always copy out data to a different drive. On this occasion i am failing to recover and copy out using an MS Windows or Dos application hence the reason to try a Linux solution.

    I wish try to use Linux to recover and copy out the data i need from the drive.

    How do i mount a drive that i am going to add to an existing SuSE Linux 11.2 system?

    How can i attempt to recover the data thats become corrupt in the this directory. Copying the data out afterwards if successful shouldn't be a problem.

    The Drive is failing.
