If original ROM/NVRAM chip on a hard drive logic board is damaged, can it be replaced by new chip and programmed with default firmware for that kind of hard drive?
Or once ROM/NVRAM damaged , hard drive is useless because hard drive is unique for each hard drive?
Thank you for reply.

In most cases, it's unique. It depends on the drive.
For example, Toshiba and new Seagates -- absolutely unique.

i may be guessing wrong but i think he's working on this drive: https://forum.hddguru.com/viewtopic.php?f=1&t=42893

If so, the answer is that the rom - besides fw code - contains the NVRAM image which is unique to every drive, so it wont work if you rewrite it from another drive.
I can reciver the original one if the data is worth it ...
