You are right in saying that PC-DOS 2.10 will NOT support a 20MB
hard disk directly. It is because the format command will only
support a 10MB hard disk.

Everex Systems (who sell mostly Seagate drives), include a software
patch for the format routine in PC-DOS 2.1, which is called LFORMAT.
This patch allows you to set up a 20MB hard drive for PC-DOS 2.1

We have been putting 20MB hard disks on PC-DOS 2.1 for quite some
time.

Personally though, I still agree with you -- PC-DOS 3.10 is the
way to go if you are pursuing larger mass storage.
