    Type
    Code:
    sudo ntfsfix /dev/sda2
    "Some people says that if you run a Microsoft Midori iso backwards you will hear demon voices commanding you to worship Satan". But that's nothing. If you run it forward it will install Microsoft Midori.

    Volume is corrupt. You should run chkdsk.

    Re: cannot mount hard drive

    It looks to me that sda2 is an Extended partition.

    Isn't it sda5 that you should mount?
    What does this disk look like in GPartEd?

    [or have I missed something obvious?]

    Question Re: cannot mount hard drive

    I have been having a similar problem;
    I recently decided to shrink my windows xp disk size from 230gb to 200gb by just chopping a section off the end to use as Ubuntu.
    A power cut occurred and the disk was right in the middle of operation.
    Afterwards I Could not boot from my windows xp hard drive.

    Ubuntu is recognizing the disk is there but cannot mount it;
    It suggested I force mount it, which i did but it says the ntfs signature is missing.

    Code:
    sudo mount -t ntfs-3g /dev/sda /media/disk -o force
    NTFS signature is missing.
    Failed to mount '/dev/sda': Invalid argument
    The device '/dev/sda' doesn't have a valid NTFS.
    Maybe you selected the wrong device? Or the whole disk instead of a
    partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
    So i checked it for consistency and this is what it says:

    Code:
    fsck 1.40.8 (13-Mar-2008)
    e2fsck 1.40.8 (13-Mar-2008)
    fsck.ext2: Superblock invalid, trying backup blocks...
    fsck.ext2: Bad magic number in super-block while trying to open /dev/sda
    
    The superblock could not be read or does not describe a correct ext2
    filesystem.  If the device is valid and it really contains an ext2
    filesystem (and not swap or ufs or something else), then the superblock
    is corrupt, and you might try running e2fsck with an alternate superblock:
        e2fsck -b 8193 <device&gt;
    I dont want to wipe the whole hard drive and start again as there are a few files i wish to keep.
    Is there a posibility of getting Some of the data back.
    Not to fussed about windows its my music I'm Worried about.

    any help would be appreciated

    Re: cannot mount hard drive

    You can always use photorec to get your data back. After all you said you just removed from the end of the partition.

    Re: cannot mount hard drive

    To the original poster, /dev/sda2 is an extended partition and cannot be mounted because is has no file system on it. The corresponding logical partition is /dev/sda5, and you should try to mount this.

    Thanks for the advice, much apreciated

    Ubuntu seems to have found all the files on my hard drive, even though it says that the drive is 'unpartitioned.'
    only a few videos and mp3's are corrupted but that soon might not be the case

    Re: cannot mount hard drive

    When I type
    sudo mount /dev/sda5

    it says
    mount: can't find /dev/sda5 in /etc/fstab or /etc/mtab

    Re: cannot mount hard drive

    If /dev/sda5 has no entry in fstab, you need to provide mount with the mount point, and maybe also the file system type. What is your mount point? To see the file system type, do
    Code:
    sudo fdisk -l
