Hrm, I'd be interested in a disk image of that HD20 floppy. I can't get my HD20 to format properly with any tools I have... (Of course, it could just be that my HD20 is dead...)

you can get HD20 startup image here

anyway I had the same problem with HD20, even if I deleted files or format the HD it behaved like it was locked and could not delet or copy any data ...
