PCB Board

I wanted to make sure I was ordering the correct PCB board for my western digital hard drive:

https://www.hddzone.com/wd40nmzw11gx6s1-wd-pcb-2060800041003-p-4005.html is your donor PCB.

When you get this PCB, you need to move your original PCB’s BIOS to the replacement PCB. The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS.

Thank you for the information. Do you provide a service to move the PCB bios to the replacement PCB?

We just sell PCB.

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.
