Nope.  HD diskettes use media that has a different coercivity.  The implication
of this is that to properly write a HD diskette you need a highr write current.
Normal (2S/2D) floppy drives don't have the oomph to write them properly, and
depending on the drive, the data may or may not be there, and if it is, may or
may not be there an hour or a week from when it's written.
