Asif,

Love the signature!

I would say it is likely it is dead, but something to confirm would be to 
look at the output of "dmesg".  There is also a logfile with similar data 
called "/var/log/dmesg".  Otherwise, you could see if it is OS related by 
trying out a live CD...see if that OS can work with the drive.>

I would really like you to be on my side,
but the side you show me isn't what I had in mind.
