I have a shuttle-xpc with an Athlon Venice 3800+ cpu, a SATA hard drive, and
an IDE CD-ROM (cdrw/dvd combo), and installed debian-etch on it about three
weeks ago. The kernel is 2.6.12-1-amd64-generic.
I can't get the CD-rom to mount disks for the life of me. It is detected
during boot-up as an ide device (all from dmesg):
Probing IDE interface ide1...
hdc: SONY CD-RW CRX320EE, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
But, then it seems to use scsi emulation, even though it tells me not to.
ide-scsi is deprecated for cd burning! Use ide-cd and give dev=/dev/hdX as
device
scsi2 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: SONY Model: CD-RW CRX320EE Rev: RYK3
Type: CD-ROM ANSI SCSI revision: 02
sr0: scsi3-mmc drive: 0x/52x writer cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.20
Attached scsi CD-ROM sr0 at scsi2, channel 0, id 0, lun 0
and I get an odd error message:
sr0: Hmm, seems the drive doesn't support multisession CD's
When I attempt to mount a disk, I get this error
# mount -t iso9660 /dev/cdrom /media/cdrom0
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
and I get this appended to dmesg:
cdrom: This disc doesn't have any tracks I recognize!
eth0: no IPv6 routers present
cdrom: sr0: mrw address space DMA selected
attempt to access beyond end of device
sr0: rw=0, want=68, limit=4
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16
lsmod lists, among other things:
ide_generic 1792 0 [permanent]
ide_disk 18176 0
ide_cd 43680 0
ide_scsi 18308 0

I originally thought it was just trying to mount on the wrong device, so
tried to mount it on /dev/hdc --- only to find that there was no such
device. I tried to create it, and that kinda failed, kinda worked, in that
they appear in /dev/.static/dev/, and there are no /dev/hd* files at all.
Putting them in manually, which I tried, amounted to nothing since they
dissapear in the next boot. Things about udev I don't understand, I guess.
I tried, twice,
# mount -t iso9660 /dev/.static/dev/hdc /media/cdrom0
and that hung badly. Could not even kill it.
So, what do I do? I don't know whether or not I can play audio cds/dvds, but
that is not vital. I need to be able to mount cd-roms, and burn them.
I got some suggestions over the net to use an ata-ide module, but the cd-rom
drive is really plugged into an ide port, so I assume this is not right.
I am using 2.6.12 since I needed that to get the kernel to find my sata drive
as /dev/sda (on my other machine, a 32-bit one using a 2.4 kernel, the drive
is recognized as ide, and probably runs slowly, but it works). Will a newer
kernel help? Is there a module I need to load? I really want this, I think,
to be recognized as an ide device. How do I do that without /dev/hdc? How
would I go about getting that device created?
