xcdroast lost my cd-rw drive?

i posted this in the newbie forum but no one replied so i'm hoping this might be a more appropriate forum.

i have a cd-rw drive (as well as a separate cdrom drive) that was working fine until just the other day. I was using xcdroast which i had just installed. I was performing a dummy burn and the app hung and i ended up killing it. now my cd-rw drive has "dissapeared" (my cdrom drive is still fine however). the line from my fstab has dissapeared and everytime i add it back it gets erased when i reboot, along with the mnt/cdrw directory and the symbolic link in the /dev/ directory.

when i run: cdrecord -scanbus i get the following:

Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J�g Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

and running dmesg only lists my cdrom drive, not my cd-rw.

I hope that is enough info. i am running redhat 9, kernel 2.4.20-8. my fstab looks like this right now:

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda5 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,user,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
/dev/hda2 /mnt/19gig vfat defaults,umask=001,gid=500 0 0

the line i added for the cd-rw drive was the same as for the cdrom but wtth cdrw instead of cdrom

the symbolic link was from /dev/cdrw to /dev/scd0 but i also tried hdd, hdc etc.

any help would be much apperciated as i've search around on the web for a day or two and haven't found a solution. thanks!

first, check your hardware is reporting correctly in whatever hardware manager you use - it's possible that something physical happened during that last test burn, causing the burning software to hang.

my setup is as follows - how much different is yours ?

append="quiet devfs=mount hdc=ide-scsi"
in /etc/lilo.conf

and the following modules loaded:
[root@Petrata caysho]# lsmod | grep scsi
ide-scsi 8212 0
scsi_mod 90372 3 [sg sr_mod ide-scsi usb-storage]
[root@Petrata caysho]# lsmod | grep cdrom
cdrom 26848 0 [sr_mod ide-cd]
[root@Petrata caysho]# lsmod | grep ide
ide-cd 28712 0
cdrom 26848 0 [sr_mod ide-cd]
ide-scsi 8212 0
scsi_mod 90372 3 [sg sr_mod ide-scsi usb-storage]

my symlinks for the /dev entries for my writer are:
[root@Petrata caysho]# ls /dev/cdrw -l
lr-xr-xr-x 1 root root 6 Oct 11 01:03 /dev/cdrw -> cdrom1
[root@Petrata caysho]# ls /dev/cdrom1 -l
lr-xr-xr-x 1 root root 13 Oct 10 17:03 /dev/cdrom1 -> cdroms/cdrom1
[root@Petrata caysho]# ls /dev/cdroms/cdrom1 -l
lr-xr-xr-x 1 root root 34 Jan 1 1970 /dev/cdroms/cdrom1 -> ../scsi/host0/bus0/target2/lun0/cd
[root@Petrata caysho]# ls /dev/scd0 -l
lr-xr-xr-x 1 root root 31 Oct 10 17:03 /dev/scd0 -> scsi/host0/bus0/target2/lun0/cd

(this is probably not the cleanest symlinking)

and my fstab entry is:
[root@Petrata caysho]# cat /etc/fstab | grep cdrw
/dev/scd0 /mnt/cdrw auto user,iocharset=iso8859-1,codepage=850,ro,umask=0 0 0

aside all this, what is listed in the kernal message log (/var/log/messages) ?
assuming most things are in order, maybe there are some references in there during the boot up.

I went hunting, and found this on google groups:
the culprit here was kudzu.

same with
(read it from the first post).

I'm guessing that kudzu is the equivalent to SuperMount in Mandrake (which sucks in v9.0 - did a test burn by accident and then went to access the disk in the burner; SuperMount spun it up and down for 20 minutes before giving up)
