[net.micro.pc] high density diskettes/low density use??

hes@ecsvax.UUCP (Henry Schaffer) (10/31/86)

One of our faculty bought a box of Verbatim high density (1.2 Mb)
diskettes.  He figured they would work in place of the DSDD diskettes
he had been using on a Televideo 802 and a modified Apple II, both of
which have been happy with the ordinary DSDD soft sectored diskettes
used by IBM PC's.  

Well, they wouldn't format on either machine, but they worked fine
on the 1.2Mb (high density) diskette drive of a PC/AT.

How can this be?
