This is only true of some PS/2 computers.  My Model 80 at home won't format
DD to 1.44Mb, and neither will most of the newer Model 70's on campus, as
far as I know.  However, my roommate's PS/2 formats to 1.44Mb regardless
(unless you set command-line options on format), and he merrily uses DD
disks as HDs all the time.  He's had several disks give way right in the
middle of files (luckily nothing important yet), but he doesn't seem to
mind.  I think that for an extra 26 cents a disk (bulk), why not go with
High Density?
