acd0a - mount_cd9660: Block device required

[Bodnar Istvan]

Hello,

regi 2X sony cdromomat szeretnem az uj controllerrel hasznalni, mivel a
regi nem volt teljesen megbizhato, de (annak ellenere, hogy a kernel 
megtalalja) sehogy se megy.. 
a mount szerint :
broken:~# mount_cd9660 /dev/acd0a /cdrom/
mount_cd9660: Block device required

a dmesg idevago reszlete : 
ata0 at 0x01f0 irq 14 on ata-pci0
ata1 at 0x0170 irq 15 on ata-pci0

a kernel :

ami talan ebbol erdekes lehet, az a :
atapi_error: MODE_SENSE - UNIT ATTENTION skey=6 asc=29 ascq=00 error=04
sor, amit sajnos nem ertek egeszen
