Comments? Suggestions? Unless Amiga drives are radically different from IBM drives, using High Density disks in a normal drive is something I'd be wary of. I know that 5.25" HD disks require a stronger magnetic field to magnetize them [what is the term for this? Coercivity?], and quite often won't work in normal-density drives. I don't know if 3.5" disks work the same way, but I'd suspect it. There's got to be *some* reason the darn things are so expensive. -- ~ From the disk of: | jms@vanth.uucp | "Glittering prizes and Jim Shaffer, Jr. | amix.commodore.com!vanth!jms | endless compromises 37 Brook Street | 72750.2335@compuserve.com | shatter the illusion of Montgomery, PA 17752 | (CompuServe as a last resort)| integrity!"
