A new self-bricking feature apparently resides in faulty firmware microcode which will rear its ugly head sometime at boot detection. Essentially the drive will be working as normal for a while, then - out of the blue - it'll brick itself to death. The next time you reboot your computer the drive will simply lock itself up as a failsafe and won't be detected by the BIOS. In other words, there's power, spin-up, but no detection to enable booting.

wahh....
actually I've so far done 3 cases before. All successful. No data no charge.
if u want, i can give u their contact number/MSN if u wanna check. They're not on LYN so they didnt post anything here. I think they just probably googled abt this problem and they found my post.
dun worry...i provide fast service. I'll do it immediately after u pass me ur hdd. Abt 2 hrs after that, i can give you back ur hdd and I'll prtscrn the screenshot of ur hdd in My Computer also as proof. 

Yeap...it is that model.
well, the 750gb drive is actually mine. In fact, the computer that i'm typing on now is using that 750gb hdd. Bricked once on me and of course i recovered it myself. The other 3 cases i did was all 500GB.

My drive was manufactured in Thailand also.

i think my ST31000340AS SD15 hdd just bricked..
