After i swapped my PCB, changing ROM chip from original board, my hard drive still not detected. It's starting, for a few seconds than stops, than starts again and stops again. Every time it stops my terminal give me this error code: Rst 0x20M ( only this code, nothing like SATA RESET).

Terminal look like this:

Rst 0x20M
Rst 0x20M
Rst 0x20M
Rst 0x20M
Rst 0x20M
Rst 0x20M
Rst 0x20M
Rst 0x20M

That is not an error, it's normal. Well ONE if those is!

Obviously repeated messages are not normal

Any unusual clicking noises?

Some connection problem maybe, try to clean up pcb connections and contacts. Or your power cable might be loose. Or ...

For '333AS' models the constant recalbrating could be a symptom of a BSY error .

Sorry for late response

pcimage,


No unusual clicking noise, it just spins up and down constantly.


hddguy,

Already cleaned, but no change, it's doing the same.



Just was thinking, is it possible the problem is that the swaped PCB was from a refubrished drive ( official refubrished by seagate) ?

hddguy,
Yes but I cant even repair this error in terminal because it dosnt spin up completely.

Some sort of firmware issue.

Easily fixable by a pro with the right tools and knowledge, but by the same token easily brickable by DIY attempts and "Internet on size fits all fixes"

Any suggestion?

I suggest you send it to a data recovery pro.

If you move the ROM back, does your donor drive still work?
