WD101EDBZ - dead ROM

Hello,
Such a long time I haven't messaged this forum but I'd really need the help of some ROM expert.

I have the following drive from a customer : WD101EDBZ with PCB model 004-0B43167.
One of the 2 ROMS (mdl IS25WP016) has a short.
Is there a way to rebuild the second ROM ?

I attached The ROM that I was able to save.

Thanks for the help !

the 2 roms should have almost identical content. Differences are in log files, so i suppose the drive should be fine if you duplicated the content of the good one. It might work with 1 rom chip as well, i haven't tested but i guess it should.

This is how my ROM parsing tool sees the ROM:

the crc of 99,9A and 9C are bad, but that's normal. So i guess it should work.

Are you referring to the 96-bit "hash"?

crc and ecc. yes

Big up to the community reactivity !
