in order to do this do i need to have the exact same model number as mine? OR can the last letters after the model number be different? ie mine is WD3200BUDT. can i use one from WD3200BEXT?

I have been told my harddrive is fine as it powers up and sometimes itll connect,its the board that has had it and that i can swap boards to retrieve my data and be working again…(alot of vids on youtube too)

Or how about using one with less or higher memory but same model?  i.e wd2500budt?

Yes, It need’s to be the same information. Avery needs to be the same including the firmware information on the PCB’s board.
