Hi,


This happens only for some CDs (2 so far).

The devices are:
acd0: <PLEXTOR DVDR PX-708A/1.06> DVDR drive at ata1 as master
acd1: <_NEC DV-5700B/1.92> DVDROM drive at ata1 as slave
pass0 at ata1 bus 0 target 0 lun 0
pass0: <PLEXTOR DVDR   PX-708A 1.06> Removable CD-ROM SCSI-0 device
pass0: 33.000MB/s transfers
pass1 at ata1 bus 0 target 1 lun 0
pass1: <_NEC DV-5700B 1.92> Removable CD-ROM SCSI-0 device
pass1: Serial Number [
pass1: 33.000MB/s transfers
cd1 at ata1 bus 0 target 1 lun 0
cd1: <_NEC DV-5700B 1.92> Removable CD-ROM SCSI-0 device
cd1: Serial Number [
cd1: 33.000MB/s transfers
cd0 at ata1 bus 0 target 0 lun 0
cd0: <PLEXTOR DVDR   PX-708A 1.06> Removable CD-ROM SCSI-0 device

The CD was written on cd0 - Plextor

If I try on the LG DVD:
itetcu_at_it> /home/itetcu/Media/Filme/_at__on_cd [0:13:20] 1
 # mount_cd9660 /dev/acd1 /mnt
itetcu_at_it> /home/itetcu/Media/Filme/_at__on_cd [0:16:38] 0
 # ls /mnt
Operatiunea.Monstrul.2.avi
itetcu_at_it> /home/itetcu/Media/Filme/_at__on_cd [0:16:41] 0
 # umount /mnt
itetcu_at_it> /home/itetcu/Media/Filme/_at__on_cd [0:16:48] 0
 # mount_cd9660 /dev/cd1 /home/itetcu/cdrom1
mount_cd9660: /dev/cd1: Device busy
