There are TWO great people I would like to Thank.
pcimage and
CK. Your advice was quite helpful. I got the T9 torx screw driver from ebay, a refurbished Maxtor hard drive from Canada and bought a new Seagate HDD. It took me less than 3 minutes to replace the PCB and there I was coping my entire work to the new Seagate. Amazing isn't it. I backed up twice just incase!!! I truly have no words to thank you two! You saved a poor PhD student his school program!! I truly couldn't afford professional data recovery and without this work I was finished. Neither had I opened a hard drive before! - Should I can claim a minor in Maxtor HDD data recovery now!!!

Probably!!!
Once again, many many many thank yous CK and PCIMAGE. I'm back to Economics which know best than computers.
Cheers!
DKN
