For Seagate donor head, it usually requirs the model number to be the same, then it's ok, but if you have more details to match, that's surely better

Seen many, many Seagates with same model number but different preamps inside.

Just out of curiosity, have you been able to get any numbers off the preamps to compare datasheets? Maybe some are the same electrically, just different physically?

PCimage, Yes, you are very right, usually the model number and the number on the preamps are the same, but if not the same, then exactly speaking, you need to match the number on the preamps inside.

However, you need to open the hdd and see that, need to be very careful about that.

A general rule of thumb is to match the 2nd & 3rd characters of the serial number for models before 7200.10.

7200.10 seems to be more particular, and I think matching preamp label codes is good practice.

Anyone agree / disagree?

FOR PCB swap , is it necessary to match microcontroller ? Like If i have 2 disks seagate 80GB both having firmware 8.01 but different chips - agare & STI , is that OK to have same model & firmware irrespective of chips used?

If you want the data then you MUST seek pro help, if not then RMA it or chuck it in the bin.

Sorry to appear harsh, but these are your options. PERIOD
