lshw shows it's there:

*-cdrom
description: DVD writer
product: DVD RW DW-D22A
vendor: SONY
physical id: 1
bus info: scsi@1:0.0.0
logical name: /dev/cdrom3
logical name: /dev/cdrw3
logical name: /dev/dvd3
logical name: /dev/dvdrw3
logical name: /dev/sr0
version: BYS3
capabilities: removable audio cd-r cd-rw dvd dvd-r
configuration: ansiversion=5 status=nodisc

but it doesn't mount, even wen there is a disk in it. I tried to mount it manually and got this:

mount: can't find /dev/sr0 in /etc/fstab or /etc/mtab

tested it with cds and dvds & it doesn't work. Works fine when booting from it so I know it's not bust

any thoughts?
