What else can I try to recover bad sectors ?

[hoctagon]

Found out my Hitachi Deskstar T7K250 160 GB Sata II have developed bad sectors.
I run the diagnostic tools from Hitachi website, and erased drive twice and fully. However, the problem still persist. I still get a red screen message saying bad sectors have been found (Device failure),to recover please fully erase drive to 0.
What else can I try to recover this drive ?
cheers

Well, I tested my drive using HD Tune to find out 2.5% of drive surface is corrupted.Last 4 GB of drive is damaged.Can not explain why.
Drive was fine until I plugged on port no 2 (sata I) on my mobo and transferred the entire content into a new Samsung SpinPoint in port 1 (sata I).

Drive was not bought through OCuk.
Can I RMA it directly to Hitachi or original vendor even If I haven`t got the packaging any more ?
