Hello,

I replaced a very old cdrom device with a newer DVD rw,
as the second dvdrw device in a workstation.

dmesg:
hda: _NEC DVD_RW ND-3550A, ATAPI CD/DVD-ROM drive
hda: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache
Uniform CD-ROM driver Revision: 3.20
scsi 2:0:0:0: CD-ROM PLEXTOR DVDR PX-755A 1.04 PQ: 0 ANSI: 5
sr 2:0:0:0: Attached scsi CD-ROM sr0


upon logging in, I get this popup error message in kde:
CD-ROM read or access error (or no audio disc in drive).
Please make sure you have access permissions to:
/dev/cdrom

udev:
cat 75-cd-aliases-generator.rules
# these rules generate rules for the /dev/{cdrom,dvd,...} symlinks
# the path of removable devices changes frequently
ACTION=="add", SUBSYSTEM=="block", SUBSYSTEMS=="usb|ieee1394",
ENV{ID_CDROM}=="?*", ENV{GENERATED}!="?*",
PROGRAM="write_cd_rules by-id",
SYMLINK+="%c"


cat 60-cdrom_id.rules
# import optical drive properties
KERNEL=="sr[0-9]*|hd[a-z]|pcd[0-9]*",
IMPORT{program}="cdrom_id --export $tempnode"


The error message device (/dev/cdrom) does not exist. Should I manually
create it? Modify a udev rule? or what?

Note: when I run K3B, I do not see both devices as active
at the same time.
Yet, I can manually load a source dvd/cd into either device
and (via dbus/ivman)
a popup appears which I can use to launch K3B and the source device
is seen, but the device with the blank dvd/cd media is blanked out. If I
switch the source dvd/cd then the device with the source disk is seen
and the other is blanked out.

Ideas on fixing this so I can load a dvd/cd into one drive and copy
to the other? (yes they are both dvdrw and cdrw devices. One is sata, the
other is ide, if that matters.

Oooops,

If forgot to include this information:
l /dev/cdr*
lrwxrwxrwx 1 root root 3 Jun 3 07:43 /dev/cdrom1 -> sr0
lrwxrwxrwx 1 root root 3 Jun 3 07:43 /dev/cdrom3 -> hda
lrwxrwxrwx 1 root root 3 Jun 3 07:43 /dev/cdrw1 -> sr0
lrwxrwxrwx 1 root root 3 Jun 3 07:43 /dev/cdrw3 -> hda

egrep cdrom /etc/group
cdrom::19:haldaemon,gentoo,james

I realize the cdrom0 does not exist, so but should that
effect how K3B works and it's ability to see and use
2 different dvd/cd devices?

It shouldn't ; you just should see in the k3b configuration what devices
it sees and tell it what to use.
