I've never been able to before, but this time for sure, as Bullwinkle used to say. May as well try copying the Plextor software disc. Not amusing at all. Nothing for it, though, tell it to copy. It trundles awhile, seems to finish, pops out the disc, and reports fatal read errors.
Machine locks up.
It's big red-button time. Play about in other ways. It never used to do that. Interestingly enough, other machines can read that disc without locking up. I suspect this reversal of drive letters is not only stupid, but confuses the system.
