Suddenly unable to mount hard drive

Postby sinclair12 on Sun Apr 07, 2013 2:51 am

Hi guys,

I searched but didnt find a solution to my problem.

So the following happened. After installing mint 12 and working happily with it for some time, one time it crashed and I was unable to access my user account. I was still able to use a guest account. Now to access my old data I tried to run my computer with a mint live distribution and plugged in my hd using an external enclosure, which worked. The device properly mounted and I could see all my data. However, after turning off the computer, the hdd didnt mount anymore. When I try to boot from it, I get a message like this: "filesystem unknown, grub rescue" and when I try to mount it on linux live gparted does see that there is a partition but cannot detect the file system.

After using sudo fdisk -l I get the following:
sudo fdisk -l

Disk /dev/sda: 4004 MB, 4004511744 bytes
116 heads, 51 sectors/track, 1322 cylinders, total 7821312 sectors

/dev/sdb1 * 2048 390834175 195416064 83 Linux

I dont know if this information is helpful, but I installed linux mint using an ext2 filesystem and with no swap space, because it would not be installed otherwise.

I would really, really appreciate your help.
