Oh good grief. EMM386 doesn't have the code or capability to mess with
disk partitions. Period.
But if drive geometry is being misreported or misunderstood under EMM386
with VDS (which appears to be the case), then my guess is that it would be
dangerous to run any kind of disk tool while the system is in that state?
Even writing a file to a disk could cause corruption.
In the same way that a keyboard driver could be dangerous to run with a
disk tool if there were a bug in it, or if it caused a normally hidden bug
in the disk tool to activate.
DOS system code is wide open to corruption from any driver or application,
a situation generally regarded as one of its biggest faults.
Without a system which displays the symptoms -- which I don't have -- it's
almost impossible for me to say what's going on. Likeliest candidate for
causing the problem is that there is still a conflict with some SCSI
interfaces and an active VDS (4bh) interrupt. We know that at least one
SCSI spec directly conflicted with VDS. However, other candidates cannot
be ruled out, or even marginalized.
