Unable to mount 1TB USB external HDD - Error
Solution 1
Ok Partition Table was the problem with the drive. i used this link http://hubpages.com/hub/Repair-Partition-Table which guided me on how to go about repairing the partition table.
So i added Gparted as suggested in article above, and i used Ubuntu Software Center to locate and install it.
after installing i opened up Gparted and it confirmed that my /dev/sdc was unpartitioned, so i created a new partition using Gparted, i thought it would "somehow" save my data but i was wrong therefore lost all my data. anyway most of the stuff was junk anyway but atleast my 1TB drive is working again YEAH :)
thanks again to the guys who provided feedback to me regarding this issue.
my fixed drive looks like this now:
muzikayise@muzikayise-supercom:~$ sudo fdisk -l /dev/sdc
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x39dcba64
Device Boot Start End Blocks Id System
/dev/sdc1 1 121602 976760832 83 Linux
best always, muzi
Solution 2
cat /etc/fsta
and look for /dev/sdb
1 , /dev/sdb2
etc
If these lines exist you need to comment or remove them. then remount the drives.
You might be forcing a non-standard file system upon your HDD.

I'm getting an error when I plug in my 1TB USB external HDD, the weird thing about this is that it was working fine before and I've been using it for about a couple of months now. yesterday I compressed one of the folders which had about 120GB of data but the compression failed after an hour and I decided to unmount the drive and shut everything down.
Today when I tried to plug in the drive I got the following error:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
output of cat
/proc/partitions

please will someone kindly assist with this?
thanks in advance,
muzi 20110203: Ok i had a look and as Jet suggested the partition table is messed up, not sure how that happened. have a look at this below partition details:
muzikayise@muzikayise-supercom:~$ sudo sfdisk -d /dev/sdc > PT.txt muzikayise@muzikayise-supercom:~$ cat PT.txt # partition table of /dev/sdc unit: sectors /dev/sdc1 : start= 0, size= 0, Id= 0 /dev/sdc2 : start= 0, size= 0, Id= 0 /dev/sdc3 : start= 0, size= 0, Id= 0 /dev/sdc4 : start= 0, size= 0, Id= 0
i'm gonna try fix this, not sure how yet but will google for solutions

samme4life about 13 yearsI'd rather see the output of
dmesg | tail
after you've plugged in the drive and seen the error message. -

Bill Cheatham over 11 yearsThis worked perfectly for me with the same problem. Something similar was in
fstab
, and this was preventing mounting, either by GUI or terminal.
