This made me remember that I have a perhaps similar problem with one of my Kaypro drives. It works at first, but eventually wears away portions of the disk making the disk unusable. (After a few uses, if you hold the disk up to the light there are arcs that are clear.) I assume this is a head alignment issue. If so, is there an easy way to realign the heads (perhaps dropping the unit a la Apple III), or should I just look for another floppy drive?
