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

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.

Hello,
There are some weird problems with those dvd burners & atapicam.
acd0: DMA limited to UDMA33, controller found non-ATA66 cable
acd0: DVDR <PLEXTOR DVDR PX-716AL/1.01> at ata1-master UDMA33
acd1: DMA limited to UDMA33, controller found non-ATA66 cable
acd1: DVDR <PLEXTOR DVDR PX-716AL/1.01> at ata1-slave UDMA33
I compile kernel with device atapicam and followed all steps from:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html#ATAPICAM
and on dmesg now I have:
cd1 at ata1 bus 0 target 0 lun 0
cd1: <PLEXTOR DVDR PX-716AL 1.01> Removable CD-ROM SCSI-0 device
cd1: 33.000MB/s transfers
cd1: Attempt to query device size failed: NOT READY, Medium not present
- tray open
cd2 at ata1 bus 0 target 1 lun 0
cd2: <PLEXTOR DVDR PX-716AL 1.01> Removable CD-ROM SCSI-0 device
cd2: 33.000MB/s transfers
cd2: Attempt to query device size failed: NOT READY, Medium not present
- tray open
(cd0 is Light-On external DVD burner connected via USB)
While burning DVDs with growisofs is working perfect I have problems
reading them :)
The only way to mount/read the DVD is to use /dev/acd0/1 - /dev/cd1,2
just does not work.
When I try to access /dev/cd1,2 I have :
Oct 9 11:50:09 thor kernel: (cd2:ata1:0:1:0): READ TOC/PMA/ATIP {MMC

It's not a big deal as I have the needed access using /dev/acd0,1, but
the some
apps can only work with SCSI devices :(
Also is there any app in base that can tell me what is the label (Volume
ID) of the DVD, or other
useful info ? :) - like "cd-info" from ports/multimedia/vcdimager/
