My brother in law threw away maybe a hundred CDRs after finding he

session was written. He thought the disc was bad since it "couldn't
read the TOC" (error msg)

That doesn't strike as particularly dumb -- the software should have been
able to reload the TOC.

I don't know why, but a lot of CD burners are unable to read a freshly
burned disc until they physically eject and reload it. Some software
will try to force this automatically, but not all drives honor the
eject/load commands. (Some, like slot-loading drives, physically can't.)
