[comp.sys.mac.hardware] Can quad-density

moriarty@tc.fluke.COM (Jeff Meyer) (11/07/89)

GIVEN:  You have a quad-density floppy (i.e. it can be formatted to 1.4MB
        on an Apple FDHD drive) that has been formatted to the 800K,
        double-density double-sided format on a FDHD drive.

QUESTION:  Can this disk be read on a standard 800K Apple floppy drive?

                           "That's why I have a few modest suggestions to
                            solve the art problem... The federal appointment
                            of an Arts Czar.  I recommend somebody who doesn't
                            know anything about art, in much the same way
                            William Bennett, our Drugs Czar, doesn't know
                            anything about drugs, law enforcement, or
                            education.  Folks, I volunteer."

I don't think the Mac OS will allow you to format a HD floppy at the
800K format. The last time I inserted a HD disk into a IIcx (which
I don't get to do often, so I remember these things) it just gave me
one formatting option, which I assume is 1.44 megs.

You can format a HD disk as 800K in an 800K drive, but a FDHD will
ask you to reformat it.
