ST1000DM003 ST1000DX001 Damaged Heads or Platter Damaged


The following is one email from one DFL user in Germany asking for the compatibility between two Seagate hard drives, one of which requires head swap.

‘DONOR is ST1000DX001
Patient HDD: ST1000DM003


i have here a Seagate ST1000DM003 – Drop down failure.

In first test i can see error message = damaged heads / and may be platter damaged

FAIL Servo Op=0100 Resp=0003
ResponseFrame EC40 0046 03B2 4900 0008 0000 0000 0000 0966 0000 0000 0000 0000 0000 0000 0000 57D1 F98F FFFF 2000 2412 0000 0000 4947 0000 4947 0000 007F 0000 0020 0012 0004 0000
FAIL Servo Op=0100 Resp=0003

I have only one donor HDD – ST1000DX001 and i know many people change heads between different hdds
and the preamp is the same.

Question: should i change the heads without create adaptive rom? (DM/DX possible !?)
or must i create a adaptive rom?

Or does it make no sense to swap the heads, what is your recommendation?

Patient: ST1000DM003 – 2 Heads
Preamp: B2 03
S/N: Z1D

Donor: ST1000DX001 – 2 Heads

For Seagate hard drive head swap, users need to check the preamp type, family, PCB number and sometimes head map, for some drives, even they have the same model number, they may have different head map.

After head swap, if the drive clicks, users need to create adaptive rom and write adaptive rom and try again. For the head swap cases, it’s very important for users to air blow the platters and the hdd inner parts and also need to check the surfaces carefully.
