MS-DOS 3.3 problem installing to hard disk

Message:

I was taking a trip down memory lane and dusted off old floppy images I had
saved away long ago. I mounted disk 1 of DOS 3.3 as a vfd and it booted
just fine into VPC 2007 where I had configured 4 MB of memory and 20 MB hard
disk. If I ran fdisk to try to setup the disk it just hung, I have a copy
of DOS 5.0 (my old favorite) so I booted that VM made a bootable floppy and
booted that into the 3.3 VM (they are completely independent VM's) fdisk
ran, format ran then I booted the DOS 3.3 again and figured dir c: should
work but I get an invalid drive error, fdisk still hangs etc... etc... I
then tried a copy of DOS 3.3a which booted, found the disk, fdisk and format
worked just fine and it installed and ran just fine. Now it has been a
really long time since I did much with DOS but I remember running DOS 3.3
(not the 3.3a) on my very first PC with 1 MB memory and 20 MB hard drive. A
quick check of vpc.VisualWin.com says that 3.3 runs in VPC (and mine sure
does) and I didn't see any notes about disks or fdisk/format issues. Has
anyone been here before and can shed some light on the error of my ways?

TIA
ron

The listing on VisualWin is for VPC 2004. A similar report for DOS 3.3 on
VPC 2007 is not available.

Ben Armstrong has blogged on running DOS in VPC extensively (mostly on
running legacy software):

Only one of the entries relates to VPC 2007. Hopefully one of the regulars
here will comment on your issue.

I found this:

http://www.mdgx.com/secrets.htm

"FYI: Officially Microsoft implemented FAT16 only begining with MS-DOS
4.00 (through extended partitions larger than 32 MB), but unofficially
FAT16 was already implemented in MS-DOS 3.3. FDISK.EXE supports
extended partitions (the only way to take advantage of FAT16 at the
time) begining with MS-DOS 3.3 (up to a total of 128 MB), but
FORMAT.COM supports partitions larger than 32 MB only begining with MS-
DOS 4.00. MS-DOS 3.3 FORMAT.COM supported partitions only up to 16 MB
(FAT12), even if FAT16 was already available."

I have all the versions of DOS so I'll see if I have the same issue.
