Hi,
I am trying to recover some data from a broken hard drive (Western Digital WD10EZEX) and was swapping the suspected broken pcb (REV A 2060-771829-005) out with a new one.
I was following this video on how to swap the BIOS chip over to the donor board when removing the BIOS chip I broke of the leg from pin 4 .
It seems like it require some rocket surgery to attach the leg back on and there's no easy way to hold it back on.
I found out that pin 4 on the BIOS chip in question (Winbond W25Q20BW) is the ground pin.
Can I just solder my BIOS chip to the donor board with no ground pin connected? Or is this incredibly naive and wont work?
