I searched to salvage my HDD data then I found your website.
My HDD info are below. Is the PCB board available?
MDL: WD40EZRZ-22GXCB0
DCX: CG04X46C4
PCB number: 2060-800055-001 REVP1
Please let me know if you need to know more information.
https://www.hddzone.com/wd-2060800055001-pcb-p-1980.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.
