My HD died and from researching some i suspect it's a component error, witch i'm going to try with first attempt.
But then i also thought, why not 'just' get the circuit board from a matching HD and swap it.

My HD is:
Seagate st2000dm006-2dm164
Looking at ebay i found a few matching ones, except one little difference.

Mine reads
st2000dm006
PN: 20M164-302

The ones i found are all
st2000dm006
PN: 20M164-316

The difference being the 302 and 316.

So my question is if it makes a difference?

I hope someone with knowledge can give a clear answer.
Thanks, David

If the drive spins up, then the PCB is most probably OK.

When searching for a PCB, search for the part number on the PCB, eg 100724095. Be aware that you will need to transfer the "ROM" from patient to donor.

The drive does not spin up at all.
I saw this video https://www.youtube.com/watch?v=M61MKqR ... nel=lapfix
and decided to try that. But, seeing as its most likely an error on the circuit board, i thought id try and get a hold of a similar drive and just swap that. And after that if successful i'd try the thing in the video.
But, i can only find drives with PN: 20M164-316 on ebay, not excatly matching mine PN: 20M164-302
So thought i'd ask some people who knows alot about this before buying one.

Thanks for your reply

Check the TVS diodes.

Something like this ...

I can see there are some youtube videos to look at for starters regarding your mentioned TVS diodes, so I'll take a look at that.
I assume I can use diodes from an other random hard drive if need be?

I just bought a multimeter today and have not used one before, so I really wanted to try out something a little more simple, like switching the circuit board from an identical HDD, so if someone knows about my original question about the SN number I'd like that.

Thank you for your reply again, I really appreciate it - and in any case I will try to repair the drive just for the fun of it.

David

careful with that, coz you might kill your data if the preamp is burnt, so evaluate the problem step by step.

I recommend contacting a pro if data is critical:

or continue your adventure if you can afford loosing it.

You don't need to replace a shorted diode. Just remove it. The drive will work without it.

Thank you both of you. I read everything in that Diode faq and I feel more confident.
I'm sure some youtube videoes will help me identify the look of those things explained, fuse, polyswitch, resistor, diode etc, and witch of them should be tested for resistance or voltage.
I'll be back If I need more help in a week or two, when I have gotten hold of a spare drive.

The data is not critical, but important enough that I want to invest some resources into trying a repair. Usually I would just trash a failed HD.

Thanks again, you guys are awesome.
