( gosh i'm quoting myself ! )

Commodore disk drives can use any DD disk, whether it's single sided or
double sided (flippable), and as most people only have single sided drives
the direction of travel of the other side isn't important. However, we
people with double sided drives, (8250 & 1571), have to turn our drives
into single sided to read them properly by running a bit of BASIC.
