cd burner/cd record problem

wildcard · n00b Joined: 08 Jun 2002 Posts: 55 Location: New York

I'm not totally sure what to do to install my cd burner. In my kernel I turned on scsi emulation, scsi cd support and generic scsi support. I also added the line hdc=scsi to my grub file. But the problem is when I run cdrecord -scan bus to see if can find my cd burner It gives me this error message
"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."

I am running as root.
Thanks
Mike

I'm not getting the failed to load messages but the files aren't there--are you building the scsi cd/emulation/generic devices as modules?

yes build it as modules the other error when i do cdrecord -scanbus it's just like yours.

are you sure you've loaded _all_ the modules?

on my pc this comes always when I plug in my usb cdrw (with scsi emulation), and the hotplug stuff hasn't yet loaded the modules

You need "scsi emulation" in your ata ide section of kernel config, and in scsi section you need:

do an lsmod and show us what modules you have loaded. Just because you did an hdc=ide-scsi doesn't mean the modules acutally got loaded. Check your list and make sure ide-scsi is on it, if not, try modprobe ide-scsi, then cdrecord -scanbus

If this works you need to add ide-scsi to your /etc/modules.autoload

This one solved all my burner problems (the info is pretty compact too). It explains how to use devfs instead of the older static stuff, which makes life a bit easier with cdrecord. :-)

I had the same problem with the same questions. Rac cleared most of them up here: https://forums.gentoo.org/viewtopic.php?t=14153 Now cdrecord works great.

thx for the replay but all my defenition seems to be ok i think the problem may be in the devfsd.conf what line should appear there i wrote
REGISTER ^sg0$ PERMISSIONS root.cdrw 666
maybe it's need to be somthing els cause i found that i have no device
in /dev/scsi/ lke it should be.

i'm trying to get this setup myself. i've read about 5 or 6 threads about it, and i believe i have tried everything mentioned. i'm not sure what i am doing wrong :)

kernel line:
kernel /boot/bzImage-2.4.19-gentoo-r9 root=/dev/hda3 append="hdb=ide-scsi" vga=733
(have tried with " hdb=ide-scsi" and "hdb=scsi" also)

bah, removing "ide-cdrom" support from the kernel fixed everything. i'm wondering why i can't have ide-cdrom and scsi-cdrom and ide-scsi?

Because you cannot access the devices using two drivers at the same time. You can have both as modules and then load the one you want at a certain time, I think.

Anyway, this is well document (not a bug, but a feature

)

ahhhh, so there is no way of telling it which kernel driver to use ? i see how using modules would have fixed this :)
