If we assume that 110 is a Linux errno, then this would be
  ETIMEDOUT       110     /* Connection timed out */

That's what my USB attached DVD drives sometimes do after having gnawed
a long time on a read error.

I am interested. Especially whether there are messages from the ISO 9660
filesystem driver.

The messages quoted by Kent could well indicate that the "CD-ROM" was found
but that rather a particular file was not readable or did not yield the
expected checksum.

It would be helpful if the error messages contained the name of the
failing software and the particular kind of read problem.

Have a nice day :)
