The reason I was being given is that in the 80 track drive, the writing head was supposed to be narrower in order to write narrower tracks. So when you format a disk on 40 track drive, this crates wider tracks. Then when you write with a 80 track drive, you will overwrite only a part of this wide track with your narrow head. So you will be able to read this narrow track in another 80 track drive, because it will only see the narrow part. But trying to read it back on 40 track drive will result in an error, because its wider head will see some parts of the wide track and some parts of the narrower track laying on it. That brought me to another question I never found an answer to: why can't you format a high density 5.25 floppy on a 1541? Only DD (and probably QD) but not HD? Regards, Michau.
