I have a TP 600E, and I reported what appears to me to be exactly the
same problem reading CDs in the bay DVD drive on this list a while back.
I've had the drive sent to IBM and replaced, but the problem persists.
On a second attempt, they replaced the system board, but that didn't
The files are read eventually, but it takes forever, and I don't think
the drive mechanics will last very long with that kind of usage. :-(

Replacing the drive did nothing for me.
