After Upgrading Ubuntu to 9.10 my hard drive now has a warning

I have a 500GB hard drive formatted as ext3: /dev/sdc1.

The disk utility does not even see this. This warning is from GParted:

e2label: No such device or address while trying to open /dev/sdc1
Couldn't find valid filesystem superblock.
Couldn't find valid filesystem superblock.

dump2fs 1.41.9 (22-Aug-2009)
dumpe2fs: No such device or address while trying to open /dev/sdc1

Unable to read contents of this file system?
Because of this some operations may be unavailable.

Did I lose something during the upgrade of the system? Was it the hard drive or the Ubuntu system that went bad?

fdisk -l output:

Recompile the kernel. It is the only way. – ta.speot.is – 2010-04-23T08:35:54.600

2@taspeotis: Are you a troll or are you trying to do something like a...joke? I can't tell right now and I'd really like to now for the future... – Bobby – 2010-04-23T08:44:49.713

Could we please get the output of sudo fdisk -l? – Bobby – 2010-04-23T08:45:35.907

1changing kernels often changes the device used to address a harddrive. your drive probably isn't at /dev/sdc anymore -- maybe it's /dev/sda or /dev/sdb or /dev/sdx. you just have to figure out where it is now, and update whatever's trying to access it at the old device path. – quack quixote – 2010-04-23T09:03:02.720

@bobby its the sdc i want to remount without reformatting – Sean – 2010-04-23T09:03:15.603

(and yes, ignore @taspeotis, he is either pulling your leg or woefully uninformed.) – quack quixote – 2010-04-23T09:04:26.850

what options would you recommend – Sean – 2010-04-23T09:34:56.460

@Sean: Something like fsck.ext3 -cf /dev/sdc1 should work. – Bobby – 2010-04-23T16:37:48.000

i got nothing with that, I then used testdisk and these instructions to use another superblock http://www.cgsecurity.org/wiki/Advanced_Find_ext2_ext3_Backup_SuperBlock

it found about 10 superblocks but i got the same error message no matter which one i put in

– Sean – 2010-04-24T21:56:56.297

@Sean: What is 'nothing'? – Bobby – 2010-04-25T15:41:45.270

sorry I had no luck mounting the drive while trying to use an alternate superblock – Sean – 2010-04-26T03:29:49.350

@Sean: I meant what error messages do you get, and does dmesg contain errors? – Bobby – 2010-04-26T07:02:36.350

I got the data off the drive by plugging it into another machine, I think it has to do with references to the /dev/sdc, gparted doesn't even want to touch it. gparted says: mkfs.ext3 -L "files" /dev/sdc1

mke2fs 1.41.9 (22-Aug-2009) /dev/sdc1 is apparently in use by the system; will not make a filesystem here! – Sean – 2010-04-27T22:12:38.880

thanks bobby for all your help it was appreciated, if I had more time on this site i would up vote your answer – Sean – 2010-05-04T02:42:12.783
