Q: I’m desperately looking for a replacement PCB of a very RARE Seagate drive.
This is a drive from the extremely scarce DB35.3 series, a ST3500830ACE:
Date Code: 08165
Site Code: TK
Number on board: 100414872
Main Controller IC: 100427288
White Label P/N: 100406541 J
A: 100414872 is your donor PCB. You need to move your original PCB’s BIOS to the replacement PCB.
