LS-120 is 120 MB; LS-240 is 240 MB, and they are conventional floppies.
 The hard CHS limit for floppies (which have a 256-cylinder limits for
MS-DOS compatibility, as opposed to 1024 for hard disks) is around 2 GB.

Hmm... I wouldn't have expected those error messages.  I'll have to
think about why.
