I did not realize when I got my Amiga that I would have to become a machinist. I have had to drill holes and tap out screw holes to try to get my hard drive to mount. I had to put another adapter plate on my mounting adapter, tap out screw holes on the plate, screw the drive to the plate and the plate to the mounting adapter. Had to use an electric drill, a center punch and hammer and a tap and die set to make it work. Am I a computer guy or a car mechanic?
