You can't plug one directly into a IIc, IIc+ or IIgs, or use it with
an Apple-supplied controller card.

They can be used with the third-party Universal Disk Controller.

As said in another followup, the only "duodisk" is a double 5.25"
drive.

AppleWorks was never supplied on a single-sided 400k 3.5" disk, as far
as I know.  Apple would have only used 800k disks.  The first version
of AppleWorks that I've seen on a 3.5" disk was version 2.0, and I'm
pretty sure that said IIe/IIc/IIgs.  It was definitely 800k.

The UniDisk 3.5 sometimes has problems reading 400k disks, but they
should be fine in an Apple 3.5 Drive.

It is more likely that your IIgs's 3.5" drive is out of alignment, or
has dirty heads, or something like that (preventing it from reading
that particular disk).
