You're in a bit of a bind - the support people say they have problems
but won't say (OR DON'T KNOW) what the exact problem is, and it
doesn't sound like the users can give you much usable information
about the problem.

Some things can be simulated easily, and some can't.
Familiar with "Pro-lock"? It was a protection scheme
that actually relied on physical damage to the disk.
Some of the more extreme uses of it actually made
an attempt to write to the bad sectors to confirm
that they really would get a "physical" error.
THAT can't be properly simulated (although replacing
the "checking" subroutine with a RET solves it)


OB_OT: Vault Corporation, the makers of Pro-Lock
went out of business due to the public reaction to
their announcement of Pro-Lock-PLUS.
