Hi,

I've got a 2TB TOSHIBA DT01ACA200 which is a rebranded Hitachi with PCB 220 QA90380 01.
The PCB is bad and i need to use a donor PCB.
I am assuming that i will need to move both ROM and NVRAM to the donor PCB.
I ROM Looks obvious but i am not sure which chip is the NVRAM, See photo.
Can you please confirm which chip stores the NVRAM.

Thanks

NVRAM acts as ROM (in simple terms). You only have one chip to transfer.
