WD4004FZWX hard drive with a faulty controller

Hi, I have a WD4004FZWX hard drive with a faulty controller, but the number on the controller PCB is 006-0A90446 not the 006-0A90641 board that you stock.

Could you confirm whether the 006-0A90641 should be a direct replacement for the 006-0A90446 board on my drive, or alternatively whether you can supply a replacement 006-0A90446 board ?

Western Digital PCB Board 006-0A90446 – $45.00 – HardDriveParts.com 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.
