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 (https://www.youtube.com/watch?v=Ng_0WaTzKmY&t=62s
) 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 https://datasheetspdf.com/datasheet/W25Q20BW.html
) 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?
