    Re: ext3 partition screwed up :(

    erlandh - The issue in this thread and the the issue in the bug report you linked to are completely unrelated. 'Cannot mount volume' is a very generic error and the inability to mount a volume could have one of many different causes.

    The problem with the OP in this thread was that their EXT3 volume had errors. Your post already suggests that your ext3 volume is clean, so you don't have the same issue as the OP, and the steps I suggested to fix it won't work for you.

    I also doubt that your issue is related to the issue in that bug report either. I don't think tune2fs would give you a good output if it was.

    How are you mounting the volume? Is it being auto-mounted or is there a line in your /etc/fstab? Could you do the following in a terminal:
    Code:
    tail -f /var/log/syslog
    Then connect your external hard-drive (you should see some messages come out on the terminal). Copy and paste those messages here.

    Thanks for your help and sorry, I wasn't aware they were unrelated.

    Here's the output of your command:

    I guess the only relevant bit is "JBD: no valid journal superblock found"? I was originally mounting this on my laptop via firewire, but as you can see, I'm now mounting it via USB2.0 on my desktop pc. It's being auto-mounted when I turn it on, it's not in fstab.

    Also, the output of
    Code:
    fdisk -l /dev/sdc
    is:

    Re: ext3 partition screwed up :(

    You said a few posts ago that you tried:
    Code:
    sudo tune2fs -j /dev/sdb1
    ...ad it output:
    Code:
    tune2fs 1.40.8 (13-Mar-2008)
    The filesystem already has a journal.
    Thats expected, because according to your output from mount, /dev/sdb1 is your root filesystem (not an external drive), which appears to be ok.

    Are you sure it's not /dev/sdc1 that you're trying to mount?

    Could you try
    Code:
    sudo fsck /dev/sdc1
    on the unmounted volume
