Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

I have a Hitachi Travelstar: IC25N060ATMR04-0
When powered on the heads go crazy for about 20 seconds then they go to the parking area and the drive keeps spinning. I get no drive ID.
I replaced the head stack and PCB from a matching donor.
The patient acts exactly the same.
The donor works with the patients head stack and PCB.
What is left?
Did the platters rotate relative to each other?
(The drive was not opened before me and I did not touch the platters)
I see no surface damage.
Servo marks got corrupted?
How do I fix this one?

Have you tried to check with the donor head but with patient PCB?

The only change is the donor head stack in the patient and the patient head stack in the donor.
The donor continues to work.
The patient continues to act crazy.
I applied some torque on the patient top platter relative to the bottom platter and nothing moved.
There is no fine dust in the filter.
The only thing I can think of is the servo track is screwed up.
Is this possible?
Can it be fixed?
