nikhil gangarde (nikhilgangarde)

I use Ubuntu 12.04LTS(64-bit) desktop edition. Lately I tried to upgrade it to Ubuntu 12.10. Everything was going good, but due to some work I couldn't complete the upgrade, so I disconnected the internet connection. Then my lappy reverted back to the original state. I thought everything was fine. But the next time I started the lappy, it said it was unable to mount the root drive.(please visit https://www.quora.com/Ubuntu/Problem-booting-the-Ubuntu-12-04-01-OS-due-to-bad-sectors-on-the-HDD for more details) Please I need to recover my data from the lappy. I tried Using the Live-CD and then accessing the HDD but it shows the following error: -------------------------------------------------------------------------------------------------------------------------------- Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dme: sg | tail or so -------------------------------------------------------------------------------------------------------------------------------- then as said in the above error I opeed the terminal and typed "dmesg | tail". It said: -------------------------------------------------------------------------------------------------------------------------------- ubuntu@ubuntu:~$ dmesg | tail [ 1446.284420] 72 03 11 04 00 00 00 0c 00 0a 80 00 00 00 00 00 [ 1446.284430] 1c c5 9b 01 [ 1446.284435] sd 0:0:0:0: [sda] Add.
