ROM IC has failure

[Syrs1981]

Hi all,

I am involved with a toshiba hdd which does not spin up

I changed its pcb with another same model (the ROM was swapped also)

now the patient PCB with DONOR ROM is ok on Donor drive , but the DONOR PCB and Patient ROM on it is faulty and the patient drive still spins not .

now what should I do to repair the ROM IC then recovering the User's data ???

Thanks in advance

Can you upload both the donor and patient ROM dumps? I have written a tool to verify the CPs.
