I'm not the knowledgable about floppies... I've heard the term GAP3 before... and know what it means but I have no idea what values should be set... > Sorry if i've been annoying you with my previous mail, but i'd like to > prevent people from faithfully believe into these heavily stressed > formats; i personally consider them dangerous, and i'm not alone here. > I'd also like to avoid the impression that it were some substantially > new idea. no problem... I don't mind... but I must say I have disks with the stressed formats (1.72meg) on DD disk punched to HD... and I have heard the data is suppose to degrade... but I haven't had any troubles... and some disks are over a year old...
