Thank you.

As others have suggested:  confirm that it's not just the CD drive, in
which case it's likely harmless.

Rather than some random manufacturer's DOS/Windows based utility,
apt-get install smartmontools, then run short and long tests and check

The short test has few false positives but only detects drive failures
about 70% of the time.  The long test takes ~30 minutes (rather than 2),
but accurately finds 95% of defective drives.

The manufaturer utilities are very likely based on the same S.M.A.R.T.
drive features.
