I managed to fix it myself.
grub.conf had a parameter hdb=ide-scsi after removing it, i can mount and read cd-roms without problems again.
cdrecord needs now --device ATAPI:0,1,0 because it can't access my writer with scsi commands

Hi
I just upgraded to FC2. Everything worked just as it was with FC1.
With one exception: My DVD+-RW.
When i try to mount a disc it complains that it is not a valid block device.
Drive: hdb: _NEC DVD_RW ND-2500A, ATAPI CD/DVD-ROM drive (dmesg)
# cat /proc/ide/hdb/driver ide-default version 0.9.newide
# cat /proc/ide/hdb/model _NEC DVD_RW ND-2500A
# cat /proc/ide/hdb/media cdrom

I saw a similar post on the fedora-devel-list a few weeks/days back.

Not sure if it is relevant for my problem. He never got an answer.
Has anyone an idea? Thanks RJ
