Question: swapping boards on seagate HDD

[galah]

Hi all,

long time reader, first time poster, etc. etc.

I have a Seagate barracuda 7200.7 120GB IDE hdd which I mananged to crack the circuit board on (don't ask how but less than 350g's ) thankfully while the HDD was unplugged from any power and not spinning. The HDD now still spins up but bios does not detect it. When the drive spins up it sounds normal and there are no "bad" noises, so hopefully the internals are still ok.

I have read on these forums that I should be able to swap the board and assuming no internal damage to the HDD I will be back in business, but I was wondering what numbers on the drive do I need to match?

I guess the following need to match:
- model number - ST3120026A
- firmware version - 3.06
But what about:
- part number (p/n - 9W2083-301)
- hda part number (HDA p/n - 100264020)
- config code - DYY-11
and I suppose the following do not need to match:
- serial numner (s/n)
- date code - 03422
- site code - AMK

Any thoughts on what I do and don't need to match? If I connect a board with wrong firmware version (for example v3.01 firmware instead of v3.06) will I fry the drive and/or the data on the drive?

Searching this forum seems to tell me I need the same firmware, but that's proving a little difficult to track down at the moment...

Thanks in advance for hopefully helping to save me somewhere between $600 - $1500 to get back my data (which is not worth $1500 that's for sure)...

noob q - I can't what???

If you put a pcb with "wrong" fw version, the drive should not fail more than it is now. But you really need a pcb from a drive with exactly the same fw version (3.06).

ah - ok thanks, that bit i understood.

Any thoughts on the "other" numbers on the drive?

i think i had the same problem as yours, i swap pcb it didnt work, with exact firmware. Only seagate lower 40G that works.

it worked but all data scrambled. and occasionally knocking.

For Barracuda 7200.7 drives, u need to match model #, firmware version, and should be same date of manufacture.

How does date matter?

Hi,

these posts are 3,5 years old... I think the problem was solved in the meantime...

rzr seems to be resurrecting hundreds of old posts, just to get an answer to his ST unlock problem.

Way to go rzr, pi** everyone off by posting hundreds of times about the same problem.
