OK. I found that MRW is Nero's InCD packet writing format. All the other
error messages just mean that the writer doesn't like the disk.
I don't have InCD installed or use packet writing. So why is Nero looking
for it on this one disk?
Clue: I experimented when I attempted to add data to the disk. I tried to
put folders into existing folders from a previous session. I suspect that
this is a no-no and Nero somehow defaulted to MRW assuming this must be a
packet writing session. I assume this disk is now has a sort of "mark of
death" in the form of a MRW format? But only with the Plextor drive? The
obvious solution is to toss the disk and start over, but is there a way to
remove the tag?
