I get the following on dmesg:
acd0: DVDR <PLEXTOR DVDR PX-716A/1.10> at ata1-master UDMA66
cd0 at ata1 bus 0 target 0 lun 0
cd0: <PLEXTOR DVDR PX-716A 1.10> Removable CD-ROM SCSI-0 device
cd0: 66.000MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present
- tray closed
Perhaps you have to update your firmware on plextor drive? Plextor
introduced advanced descriptions for new and/or corrected dvd types in
there updates.
Give

a chance.
