I have the same problem here with a 160GB Hitachi HDD
Actually, no. Thanks for the picture. From that picture we now know your disk is a Seagate ST9160412AS, and not a Hitachi.
Mounted the HDD in an old Fujitsu laptop, and MHDD recognizes the HDD
You didn't fully answer my previous questions, but I'm guessing that the lack of correct recognition by MHDD in another PC was probably due to the specific SATA controller setting which is sometimes needed for MHDD (and HDDErase and some other software) to work correctly. I have explained this is several previous posts, so you can search for it if you want more details.
The HDD came password protected, therefore I don't know the password for it.
Therefore this looks like a genuine ATA password (which I'm not convinced was the situation for the OP, whose thread you have hijacked
). There have been previous threads about Seagate password removal.
