LInux (Ubuntu) Question - Unable to Mount Internal Drive

[TimmyBoston]

I have two internal harddrives, one serves as a backup for video, music, pictures etc. It's not my home folder or root. I had a power outage and it screwed this up. This is the error message I get when I try to open the drive from the Places Menu:

Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Any idea how to fix this? I'm totally lost.

I ran dmesg | tail in the terminal and here is the error:

dmesg | tail

Any ideas on how to fix this so I can mount this drive and recover the data? Thanks!

Was this hard drive working or is it a new drive in your machine? You could reinstall on that drive, but you would lose all the data - if that matters. There is a disk recovery option in the installation process, but I've never used it. Which Ubuntu version?

[TimmyBoston]

The drive has been in the computer for quite some time (and was working until the power outage), it is full of info. Formatting it isn't an option. I'm using Ubuntu 10.10

It looks like your EXT3 FS is corrupted or the journal is messed up.

I think your only hope is that FSCK can fix this - otherwise your data is probably gone.

Unmount the drive and run (as root, probably):

fsck.ext3 -p -v /dev/sdc1

Read the manpage before you do this, of course.

EDIT: Oh! I forgot to mention that your problem is not Ubuntu-specific. The FS or journal got corrupted because the power went off suddenly - not good for the drive.
