I have a WD Charger that just stuck on busy with the original ROM and unlocked ROM and with SATA PCB and with the original USB PCB converted to SATA. so I cannot use the function "Block SA Aceess" because it has to write the ROM directly into the HDD using SATA which is impossible while the HDD stuck on BSY.

is there a way to block SA access in ROM read from a file and save it also into a file so I can write it back using a programmer?

Isolate the heads worked but it took hours to get RDY, and after blocking SA access now Stuck on BSY as before

PM me. Send across the rom I will bypass it (02,411,SA) and give it to you.
Cheers.

if you still fail with all the three then fault is elsewhere..
