I just got something like this working a few days ago. What I did was to
install a real-mode critical error handler which tells DOS to fail the disk
operation and sets a flag which I can test from protected mode. Or,
rri!potter AT vtserf DOT cc DOT vt DOT edu (Mark Allen Potter) sent me some sample code which
works by a real mode callback. I can send you a copy of my code tonight or
post it if it is of general interest.
