I have the same exact P/N as this board from your website link – https://www.hddzone.com/wd-pcb-2060800041003-p-3416.html
I was wondering, is the highlighted part in the image below the BIOS that I need to swap, if I buy this replacement board? If no, can you tell me what it is, the guide on that page does not make it clear. Thank you!
It is the BIOS.
You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Please refer: https://www.hddzone.com/hard_drive_pcb_firmware_transfer.html Or you can find an electronics repair shop help you.
