One of the things on my todo list is to put a logic analyzer on a 2.4meg
drive and see what happens when you put 1.2 or 2.4 meg media into a drive

Dave, if you could spare some media, I'd like to get a couple to experiment
on so I don't have to risk the ones that I bought.

The media itself is VERY different from 1.2 meg floppies as it uses vertical
recording.
