    Possible HDD Failure


    Hello,

    I am not 100% sure if the problem is in the NTFS partitions or the hard drive itself, so I figured I'd ask those who know more about this than me before giving up on the hard drive.

    First, as a background, this is not my laptop, and it has only Windows 7 at the moment (with a linux live CD). As such, I unfortunately do not have access to the laptop beyond telling the owner what to do over the phone.

    Apparently, she had her camera case (which has a magnet) near the hard drive of her laptop for an extended period of time, and only noticed when she heard a clicking sound. She immediately turned off the laptop, and noticed the camera case's position. I'm personally surprised that moderate-strength commercial magnet could damage a computer, given the powerful magnets in the hard drive itself and various other testimonials, but it seems possible at this point.

    In short, when she turns on the computer, the POST screen is displayed, and she can access the BIOS. However, the normal page afterwards (I forget what it's called, but where all the interrupt handles and hardware information is listed) is not displayed. It's simply a black screen for what she says is around a minute, and then a page shows up that simply says "Windows is loading files" on a black background with white text. She has left it to do this for several hours, and it was still running.

    I told her to create a Ubuntu live CD (the distribution that I use most frequently), and have been trying to diagnose the situation. The Live CD will load, but cannot mount the hard drive.

    For reference, her hard drive has three partitions:
    Code:
    /dev/sda1: Dell Utility
    /dev/sda2: Windows recovery partition
    /dev/sda3: Main Windows partition
    First, I had her check the partition health using gparted. On opening gparted, /dev/sda1 is listed as healthy. However, sda2 and sda3 are listed with warnings. Unfortunately, I forgot to write down the warnings, but they mentioned problems with the partitions.

    Attempting to mount using the following commands:
    Code:
    mkdir /media/ntfs
    sudo mount -t ntfs /dev/sda3 /media/ntfs
    Results in:
    Code:
    ntfs_attr_pread_i: ntfs_pread failed: Input/output error
    Failed to read $UpCase, unexpected length (-1 != 131072).
    Failed to mount '/dev/sda3': Input/output error
    NTFS is either inconsistent, or there is a hardware fault, or it's a
    SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
    then reboot into Windows twice. The usage of the /f parameter is very
    important! If the device is a SoftRAID/FakeRAID then first activate
    it and mount a different device under the /dev/mapper/ directory, (e.g.
    /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
    for more details.
    Next, ntfsfix gave the following:
    Code:
    ubuntu:~$ sudo ntfsfix /dev/sda3
    Mounting volume... __ntfs_volume_release(): Inode 10 still have 1 references.
    FAILED
    Attempting to correct errors...

    Setting required flags on partition... OK
    Going to empty the journal ($LogFile)... Failed to empty $FILE_LogFile/$DATA: Input/output error.
    FAILED
    Failed to reset $LogFile: Input/output error.
    Then, using smartctl:
    Code:
    sudo smartctl --test=long /dev/sda
    Results in:
    Code:
    ubuntu:~$ sudo smartctl -a /dev/sda

    From the above, the following line worries me:
    Code:

    That's a lot of bad blocks, if I understand the output correctly.


    In summary, I don't know where to proceed from here. Is the hard drive dead, or can it be fixed? If it's not fixable, will I still be able to get data off of it by attaching it as an external slave drive to my computer, when I next see her? I have a cable that allows for connecting 2.5'' SATA drives as if they were external hard drives, which I have used in the past to get data off of failing hard drives, but I'm not sure that will help in this instance.

    Thanks for your help!

    You probably need to run testdisk on it.

    It would be more convenient to have it where you can work on it. Testdisk is available in various forms. It's probably on your repositories, or you can get it on a self booting iso, and make a CD to run on her computer.

    If your main plan is to recover her data, sda3 would be your focus. If you intend to recover her OS with it's data you'll need to restore the whole disk.

    Yes, you probably can restore the whole disk with testdisk. just read the directions as you go along, and pay attention. (And don't make any promises!)

    Yeah, I wish that I had it with me to work on it in person. However, it's currently 3000km away. Ah well.

    I had not heard of testdisk before. Thank you very much! I'll be sure to look into it.
