try using a real 720k 3.5" floppy and format it on the DOS 2 system, you
might have better luck reading it
failing that you can try covering the HD hole (the one opposite to the
write-protect tab) on a high density disk and formatting it as a 720k...
though HD disks dont often work well as 720k disk because the media is
actually different, but it's worth a try

It sounds to me like it would be quite a non-standard format,
as I don't believe DOS 2.11 supports the 1.44meg format. Anyone
else?
Yes, that bothered me as well....
Also, most machines that run MS-DOS 2.11 are XTs. Which may well not
support high density drives at all (yes, I know there are high density
controllers for XT machines, but they're not that common).
I am wondering if this is a 1.44Mbyte disk at all. It might be formated
as a 720K disk. In which case a machine with a high density drive and
controller might get very confused.
Also, does MS-DOS 2.11 know about anything other than 360K disks? It
might only be using the first 40 cylinders of the disk (and %deity knows
what it's doing to the directory).
