WD 2060-771814-001 PCB’s BIOS

Q: I want to find the PCB for my WD hard drive.
WD10TMVW-11ZSMS5 (USB interface, no SATA).
Model: WDBACX0010BBK-PESN
number: 2060-771814-001 REV P1
How many chips on the PCB need to be swapped? I’ve heard of U12 / U14 chips? Could I just take it to an electronics shop?

A: 1. For most WD PCB swap, just need the donor PCB has the same board number – 2060-771814-001 as the damaged one.
2. This PCB has 2 BIOS, as the below photo:

3. You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Please refer: http://www.datarecoveryunion.com/hard-drive-rom-chip-swapreplacement/.  Or you can find the electronics repair shop to help you.
