SEAGATE 200GB 7200.9 PROBLEM WITH PCB OR HDA?

[Damon]

A friends of mine brought to me suddenly broken hdd as below. No signs or smells of fried components on the PCB. The motor is not starting, but hdd has some strange noise.

Before I start to think about sending it to a pro, I would like to give it a try with swap of PCB.

My questions are:
Which number i have to match with donor: from white sticker 100xxxxxx or from printed reverse on the PCB 100387574?
Should I transfer ROM chip only when firmware is different on donor PCB?
Is there any compatible SATA version of donor PCB?

Thanks in advance for any help!

Bad Heads.

Thanks for reply.

Contacts cleaned, but problem remains

Jerovsek, you have written to match model and FW, but I didn't get answer to my question: should I match number from sticker or from printed number on the PCB?

Sounds like head stiction to me, new PCB won't fix that.

if you insist, you have to match the printed number (and the first part of the sticker number will be matched anyway)

Thank you jermy for straightforward answer.

I am aware that it could be the serious problem with heads, but anyway I would like to try swap PCB. It's not expensive.

100% stiction
outsource it

Hello demon
When PCB swap you need PCB no and firmware matching

[Damon]

Hi Guys,

I have found proper donor to see if that can help anyway, but as you supposed it didn't. PCB is 100% ok. But at the same time after few attempts the drive suddenly started to spinning again. But that's the end of the good news as it still won't be recognized by the computer. There is still something wrong anyway, something with heads?

Finally, any pro from Poland? I would like to discuss possible price range for this job for my friend before I will outsource it.

Ouch, this is why you don't want to replace PCB for a stiction problem. It looks like it has broke free, but possibly ripping heads off or damaging them in the process. Any further spinning is likely causing much more damage and it could have made an easy job very difficult.
