Well to start, I bought a external 400k Drive for my 512, and first I needed clean and oil the drive to the mechanical parts because the drive had seized. So now I inserted a disk which was already formatted and it asked me if I wanted to initialize it so I said yes and it started to run then spit out the disk. Well hours later the drive had been oiled, the head had been cleaned, oiled again, and so on. IT STILL DOESN'T WORK! I am dumb founded. Why doesn't it work? Any suggestions will be helpful.
