This is because the drive runs at 300rpm (just like normal DD drives) when reading/writing DD floppies, but slows to 150rpm when reading/writing HD floppies. This is how the drive fits twice as many sectors on a track while maintaining the same data rate.

The Power Computing XL external High Density floppy drive needs no patch to read HD floppies; the patch is required only to write/format them.
