Locked out of HDD

[Pritam Baral]

As I said, I used hdparm [--security-set-pass] to set the password.

Its a Toshiba MK325GSX. It came with the laptop.

Since I know the password, I can perform a SECURITY_ERASE on it, but
if only i can boot up my system!

Yes, I have searched the net. But all i can find are forgotten
password cases, not my case.

Thanx. . .
