Hi all,

My HDD burned (controler for the engine), so I decidet to get the same one and to relace the PCB. Today I get the new one how ever with different HW revision. And it doesnot work. Does any one have any advice what to try???

Description:

HDD Seagate Momentus 5400.6 ST9250315AS

old one (damaged)
SN: 5vc7044B
PN: 9HH132-286
FW: 0002SDM1
Date: 10092

new one
SN: 5vcbpdje
PN: 9HH132-500
FW: 0001SDM1
Date: 10221

The PCB is the same how ever it differs in used components slightly. It uses different chip for the motor control.
After swithching the PCD motor runs, how ever the head is seeking. HDD remains undetected. Is there any significant difference in those two revisions or would be possible to change firmware or data disk it self (I have access to the clean room). The question is if the geometry of the disk is he same or not. I would be glad for any information I have valuable data on it. How ever I don't want to spend the fortune on the profesional data recovery. I will be glad for any information

Best regards

Pepa

If after exchange PCB hdd did knocks sounds, HM HM by terminal that could be meaning damage inside HDA, the cause the damage shorcut could be pass into MHA " Magnetic head Assmebly" , on this way u need a DR Lab for that process ,f i no knocks " partial recalibration" so that should me mean un need wrote adaptives info into u Donnor PCB u could check that too by terminal

Hi,

It is the new architecture, so it won't emit HM messages.
I am sure a rom transfer is still to be done.

Correct me if I'm wrong, but this is F3 architecture.

In which case the ROM is unique and contains adaptive data even down to the serial number, so a ROM swap is essential.
