This 1TB WD had a visibly blown-up motor control chip. With hot swap, drive stayed busy but stayed spinning. ROM is embedded in microcontroller chip.
Replaced blown motor control chip and extracted ROM info. Programmed to donor PCB. Drive powered on and stayed busy. Figured preamp took damage with the power surge.
With new heads, drive comes ready and IDs. Only FW mod I wasn't able to read was Mod109 from SA0 but got it from SA1 and wrote it to SA0. Can't view sectors in HEX. On DDI, can build heads map and media test is all red A--abort error.
Read/write test reports H0 is in read-only mode.
Same results with patient PCB (with repaired motor chip) and donor with extracted ROM written to it.
I suspect it needs a translator regeneration but I haven't encountered this specific issue before and was hoping to get a consensus.
Thanks!
