    Suddenly cannot mount NTFS external hard drive

    Hello all, I wonder if you could help me out. I'm not a very knowledgeable user so it would be appreciated if any help could be kept simple.

    So I have a Hitachi 1TB external hard drive. I don't have it plugged in all the time, and when I need it, I mount it by

    Code:
    Code:
    sudo mount /external
    But now I get an error mesage:

    Code:
    ntfs-3g: Failed to access volume 'UUID=9218E01B18DFFBDB': No such file or directory
    
    ntfs-3g 2010.8.8 external FUSE 28 - Third Generation NTFS Driver
    		Configuration type 1, XATTRS are on, POSIX ACLS are off

    I dual-boot with Windows, but I cant access it there either.

    Any ideas?

    If you can't access it from windows either, it may be faulty or corrupted.
    Have you tried the disk utility in system>administration menu?
    Can you see the drive in there?
    Are there any partitions visible?

    If yes to the first and no to the second, the disk partition table may be corrupt.
    This can often be recovered.

    A couple of comments.

    Why? External NTFS driver are automounted by the system when you plug them in. Was this one not automounted?

    That doesn't sound good.

    Plug the drive in, switch it on but don't try your mount command. Instead, run these two commands from the terminal:

    Code:
    sudo fdisk -lu
    dmesg | tail
    Post the two outputs. That may tell us something.

    Re: Suddenly cannot mount NTFS external hard drive

    Neither fdisk nor dmesg show any sign of the system recognising the Hitachi drive. This indicates a hardware problem rather than just a filesystem corruption. Taking things in turn, the problem could be the drive power supply, the drive enclosure, or the hard drive itself, or the computer USB interface.

    Take the last one first. Do other USB devices work on the computer USB interface that you were using?

    USB brick power supplies do fail occasionally. Are you getting a light on the enclosure? Even if you are, the power supply could be failing, delivering inadequate voltage. If you have a compatible one, try an alternative power supply.

    Next thing is to remove the HD from the enclosure. Do you have another enclosure you could try it in? If not, as it's probably a SATA drive, and if you have a desktop machine rather than a laptop, try connecting the bare drive to the motherboard. Or if you have an eSATA connector you could try that.

    Lastly, for completion, if you have another usable SATA drive, you could put that into the enclosure to see if the enclosure itself is working.

    Re: Suddenly cannot mount NTFS external hard drive

    Thanks for your help, but it suddenly started to work.

    I plugged it into another XP machine and it loaded up as normal. I then retried mounting on Ubuntu and things were fine. Now if you's excuse me, I'm going to go and back everything up.
