[svlug] CD-R/W Problem

[Scott Thompson]

So here's what happened.  I turn my machine off for the night.  I 
power-up the next day and launch XCDRoast.  XCDRoast tells me there is a 
problem with my SCSI buss, and can't see my CD-R/W (HP 9300) so I do 
some investigation.

First, XCDRoast with it's -i and -f options respectively.  Nope.

Next:
akhnaton:~# less /etc/lilo.conf
<snip>
append="hdd=ide-scsi"
</snip>

OK...
akhnaton:~# less /var/log/dmesg
<snip>
Kernel command line: auto BOOT_IMAGE=Linux ro root=303 hdd=ide-scsi
<snip>
hdd: Hewlett-Packard CD-Writer Plus 9300, ATAPI CD/DVD-ROM drive
<snip>

OK...
Drop in a known good CD (with data):
akhnaton:~# mount /dev/hdd /mnt
mount: block device /dev/hdd is write-protected, mounting read-only

OK...
Try again as SCSI:
akhnaton:~# umount /mnt
akhnaton:~# mount /dev/sr0 /mnt
mount: you must specify the filesystem type
akhnaton:~# mount -t iso9660 /dev/sr0 /mnt
mount: /dev/sr0 is not a valid block device

OK...
akhnaton:~# ls -l /dev | grep sr
<snip>
lrwxrwxrwx    1 root     root            4 Mar 15 23:18 sr0 -> scd0
<snip>

OK...
akhnaton:~# ls -l /dev | grep scd
<snip>
brw-rw----    1 root     cdrom     11,   0 Mar 14  2002 scd0
<snip>

So, any ideas?  Because I'm out of 'em.  Two days ago I could write CDs. 
  Today I can't.

Thanks,
~Scott
