Hardware engineering...

Today fine morning i went to dinagar's house who is a college friend of mine. his harddisk was in problem and he was not able to access it for the past weeks.. so i went to his house to check it and repair it. i could figure out the problem but failed rectifying it. i was not sure why it did not got repaired. i asked him to bring the harddisk to my home for checking and repairing at my home.

at home i connected his hard disk and then used testdisk utility, partition magic for recovery. nothing really helped recovering his hard disk data. so left it with it. i told him to consult a hardware engineer for recovery of his data
