CDRW doesn´t work anymore

[KeTZer]

I´m working with a Knoppix HD-Install that works fine so far. In the beginning both drives worked fine, but the after a kernel update to 2.4.24 the automounter screwed up. I turned out because of the newly installed grub. I didn´t know that I had to pass hdc=ide-scsi and hdd=ide-scsi to the kernel. Now both drives are configured exactly the same. They are attached to scd0 and scd1. But the problem ist, that only one drive can be mounted. The other one just blinks a few times then a few times again and then again and then I get this error-msg:

root@Blackheart:~# mount /dev/scd1 /mnt/cdrom1/
mount: Einhängepunkt /mnt/cdrom1/ existiert nicht
(or in english: mount: Mounting point /mnt/cdrom1/ doesn´t exist)


Now some further stuff you might want to read:

(/dev/cdrom and /dev/cdrom1 are symbolic links to /dev/scd0 and /dev/scd1)


Ah, and K3B just tells me of an I/O error when I try burning something...

So, I hope that someone can halp me with that prob...

root@Blackheart:~# mount /dev/scd1 /mnt/cdrom1/
mount: Einhängepunkt /mnt/cdrom1/ existiert nicht
(or in english: mount: Mounting point /mnt/cdrom1/ doesn´t exist)

That's an easy one.

mkdir /mnt/cdrom1

Beats me. Never really used k3b before. By the time you get it configured I've already burned 2 or 3 cd's. :) Perhaps just a configuration issue.

[KeTZer]

That's an easy one.

mkdir /mnt/cdrom1

Don´t think so; in mnt are symbolic links like cdrom1->/mnt/auto/cdrom1
and I think that is right as it is.

[KeTZer]

Is there really noone who can tell me what´s wrong?

[OErjan]

according to this, you have it on sr1 and sr2.

Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
Attached scsi CD-ROM sr1 at scsi0, channel 0, id 1, lun 0
sr0: scsi3-mmc drive: 32x/32x cd/rw xa/form2 cdda tray
sr1: scsi3-mmc drive: 18x/40x writer cd/rw xa/form2 cdda tray

try first to make the mountpoint (as root)

mkidr /mnt/cdrom3
then mount it as below (still as root)

mount -t iso9660 /dev/sr1 /mnt/cdrom3
if this works you edit the links /dev/cdrom and cdrom1 so that they point to sr0 and sr1 if i am not all wrong they should not point to scdX .
hope it helps.

If I do it the way you described the CDRW just flashes a little and then mount says that there is no disc in the drive (Tried it with different ones...).


Here is something from my syslog that might mean something:

What made me courious is that this "Uniform CDR Driver" is only loaded after the first drive and not after the second one (wich is the problematic one).
Don´t know if that has something to say....

[OErjan]

weird, it SHOULD work. hmmmm.
what does lsmod say?
and likewise output from
hdparm /dev/hda
hdparm /dev/hdb
hdparm /dev/hdc
hdparm /dev/hdd
and try what i gave above after booting with cheatcode nodma.

keep at it. sooner or later some fix will emerge.

hda and hdb are working hdd´s, hdc is a workind dvd-drive and hdd is the CDRW

[OErjan]

do you have the line append = "hdd=ide-scsi" in your lilo .conf (like this):

# LILO configuration file
# Start LILO global section
append = "hdd=ide-scsi"
boot = /dev/hda
prompt
timeout = 50
# VESA framebuffer console @ 1024x768x256
vga = 773
# Normal VGA console

if not add and reboot. then give me
dmesg|grep * where * is replaced with sr, sc, CD, ATAPI, rw and finly ide-scsi.
I refuse to give up, there is some minor thing i have missed here.

[Durand Hicks]

Your modules and/or kernel is tainted. Looks like a recompile of your kernel or modules is in order.

[KeTZer]

My Kernel is tainted because of the NVidia Drivers, which I use.

dmesg|grep *
with any of the devices suggested does not give any output...

[KeTZer]

Thank you people for the help, but the problem has solved itself as I tested the drive in another computer and it wasn´t recognised by bios. Shortly after this some chip in the drive got extremely hot and left for chip heaven...
