Just an after thought. Would it be possible to recover data using some

if your hdd is recognized by the system ( Linux ) ... you can use " 
testdisk " see[1] to recover the data

This is most probably a hardware fault  and I doubt you can do
anything with Ubuntu to fix it. If it's a HDD with USB casing you
could try to connect the drive directly to your system (internally)
and try to recover the data using dd_rescue or similar tools.

In any case, it's best that you make arrangements to get it replaced.

[ubuntu-in] External USB hard disk not recognised after a power failure during operation

2010-05-31 Thread Alok Singh Mahor 
I am using Ubuntu 10.04 and win XP.

While I was playing some songs from my HD on windows  suddent power
got disconnected from my HD. When I plug it again it was not
recognised(on windows). Actually windows even doesn't boot while HD is
plugged in.

Then I came to Ubuntu(usb still plugged in) but again Ubuntu was
taking a lot of time for booting, then I unplugged HD and system
booted normally. Then I plugged HD again but it was not recognized.

After that I tried few commands:

lsusb:
It doesn't give any output when HD is plugged in.

When plugged out lsusb gives normal output.

Here are the last few lines of the command 'dmesg' which I think is
showing some errors
