i usually do. i don't recall the make of my cd-rom drive offhand, but
the kernel reports it as "TOSHIBA CD-ROM XM-6202B, ATAPI CDROM drive".
Too lazy to check my box-o'-dox.

To make sure it's reading the data correctly from the CD, cdparanoia
reads the data several times and compares the results. 'jitter' is the
quality that these repeated measurements don't match. Your Plextor seems
to have a rather high jitter index.
