Fujitsu MHY2250BH Clicking and in Busy State

[odedshankar]

Hi Guys,

I wonder if you can help me identify the issue with a fujitsu drive I got from a customer. I can’t find anything relevant on forums as these drive are not that common.
It is a : Fujitsu MHY2250BH, CA06889-B30900C1, 0080890B
It makes a clicking noise and when connected to HD doctor it stays on busy state.
I got an exact donor drive which function good and I have done the following:
1. Replaced PCB from donor to patient – still behaves exactly the same.
2. I opened 2 drives in a clean room and noticed the following:
Patient drive – heads looks physically undamaged but they move from side to side of the platters without stopping – in and out – that what makes it cliking.
Donor drive – heads moves from parking area to internal edge of platters and stop there.

What do you think is the problem,
Any help will be good,

Heads bad, and quite possibly media damage. Often is on this series

And if it's from Apple even worse

Just a quick update regarding the result.
Did heads replacement and still had the same problem.
Tried another head replacement and it worked perfectly - imaging the data as we speak.

Cheers,

Nice. So means that first head stack wasn't compatible.
Can you post details of all 3 drives?

[odedshankar]

Sure mate, all 3 were the same:
Fujitsu MHY2250BH,
CA06889-B30900C1,
0080890B

did u try to put back the heads to the donor in the swap #2 to see if they were not compatible or simple demaged in the operation?
