have to say i'm not expert for repairing hdds, and hope someone of you great experts can help me, my case is following, have WD My Passport external hdd 2TB with this PCB 2060-800067 , accidently broke usb connector and part of original PCB around usb connector, so it doesnt work anymore...
Ordered same PCB at ebay.com , replaced BIOS IC, but seems for this PCB, lock not in BIOS IC, but in MAIN IC - Marvell IC ... Please if anyone can confirm me, if i remove Main IC from old-original PCB to this donor's PCB, will this solve my problem to access my hdd's data, (bios is is already moved from orig to donor's pcb) ?
No. If there is an external ROM (U12 labeled 8-pin chip) then there is no adaptives in the main IC. I've never seen an embedded adaptive in the main IC on any 8xxxx series WD PCBs.
It was the U12 you moved right? And, are you sure it's correctly soldered on, not upside down or something? Also, did you pay attention to the part of the PCB number after the final dash (E.G. 2060-800067-002) That can make a difference on these. For example 3Tb PebbleB family PCBs aren't cross compatible with the 4Tb & 5Tb Spyglass/Spyglass 2 family PCBs even though they can share the same PCB number.
This board is also very easy to damage since the ROM is right next to the main IC and other components.
