hello guys
I have a patient seagate hard drive st4000nm0035 with board number 100760706. The registers do not turn on and the spindle does not turn. I got a donor board and put it on the patient's hard drive without writing the patient's ROM. The spindle spun with a screeching sound and the BSY register lit up.
Then I write the patient ROM on the donor board, to my surprise, the spindle did not spin again and the BSY, DRD, DWF, DRQ, CRP registers are pale green.
Can anyone guide me?
by regards

Best to open it in the cleanroom first and take a look inside. You might be wasting your time with the ROM.

hi dear
I also thought it is Headpark. But it wasn't.
Why doesn't the spindle spin with its original ROM, but it spins with the native ROM ST6000nm0115?
When I write the patient rom on the donor, the spindle still does not spin.

Sound like the patient ROM is corrupt. Post a copy here.

Thank you for your time.
ROM is attached

my friend
Do you know the terms of PCB swap? Do the two hard drives have to be exactly the same, or is it enough to have the same PCB number?
