Hard disk fail

Hi all,

I don't know if this is the appropiate forum. Forgive me if it is not, please.

When I try to mount my usb disk (750GB, ext4) I got

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

so I do dmesg | tail

sd 7:0:0:0: [sdc] ASC=0x11 ASCQ=0x0
sd 7:0:0:0: [sdc] CDB: cdb[0]=0x28: 28 00 01 54 08 4f 00 00 18 00
end_request: I/O error, dev sdc, sector 22284367

sd 7:0:0:0: [sdc] ASC=0x11 ASCQ=0x0
sd 7:0:0:0: [sdc] CDB: cdb[0]=0x28: 28 00 00 00 00 41 00 00 02 00
end_request: I/O error, dev sdc, sector 65
EXT4-fs (sdc1): unable to read superblock

Can I recover the data on this disk? Is it posible? How to do?

and, Could it be a hardware failure? How to know it?

Thank you in advance,

kInU.

Re: Hard disk fail

did you try to fsck the partition?

Re: Hard disk fail

sd 7:0:0:0: [sdc] Sense Key : 0x3 [current]
end_request: I/O error, dev sdc, sector 65

Those errors are usually indicative of hardware failure on your drive. You can try an "fsck" as mkheagle8 suggested.

Then try smartmontools: http://wiki.archlinux.org/index.php/Smart

If that does not work burn your self a copy of the Ultimate Boot CD and see if you can repair the hard drive with its hard drive tools.

Re: Hard disk fail

Hi,

fsck gives me:

fsck from util-linux-ng 2.16.2
e2fsck 1.41.9 (22-Aug-2009)
fsck.ext2: Attempt to read block from filesystem resulted in short read mientras se intentaba abrir /dev/sdc1
¿Esta podría ser una partición de longitud cero? -- this could be a zero length patition?

Today I'm gonna get Ultimate Boot CD, but.... Do the Seagate tools recover some data? I have some files I'd like to rescue.

Re: Hard disk fail

AFAIK the Seagate tools will attempt to repair bad sectors but they are not data recovery tools. See if you can fix the drive first then worry about data recovery after that.
