I have a IC25N080ATMR040 it doesn't spin up.
After changing PCB it spins up but no drives are detected.

As I understood SA Information ist keept in NVRAM.

I thougt last task to restore data would be to copy NVRAM.
What can I do to copy "NVRAM" ? What tools can I use.
Sould I solder the NVRAM. Can it be erased while soldering???

Is there another possiblity?

You can move NV RAM if you have good reworking skills. You can read/write nv ram with expensive tools. Also with expensive tools you don't need native NV RAM and can still recover data.

Give this to a pro if its important. Should be cheap enough if you dont do anything else to it. If you lose NV RAM chip or damage it then the price will be a lot more.

Okay some more question

1. If a "pro solder" destroys original NVRAM while solding/desolding. Does that means everything is lost?

2. Is there another way. Sending Both PCB to someone doing the job?

1. Lost for you. Not for me.

2. Possibly. Ask someone local.
