I've just installed Slackware 10.0 on a USB hard drive attached to an IBM T30. I've got everything working except the CDROM. When I try to mount I get -
root@darkstar:~# mount /dev/cdrom /mnt/cdrom
mount: /dev/cdrom is not a valid block device
when I cdrecord -scanbus I get -
root@darkstar:~# cdrecord -scanbus
Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg 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'.
The appropriate section in my lilo.conf looks like -
# Linux bootable partition config begins
image = /boot/vmlinuz
initrd=/boot/initrd.gz
append="hdc=ide-scsi"
root = /dev/sda1
label = Linux
read-only # Non-UMSDOS filesystems should be mounted read-only for checking
# Linux bootable partition config ends
Just curious. IF this is a cdrom and not a cdrw why did you append ide-scsi in lilo? YOu state yourself it works without the append. The only reason generally to do that to the device is to get scsi emulation working to burn cds.
Originally posted by mago It should be linked to dev/sr0 instead of /dev/hdx
you'd have to make sure it's sr0, cuz it could be sr1, etc.... depending on the setup... i haven't read through the setup description above, so i'm not sure...
Well. Tried all sorts of things as a result of googling the problem various bits&bobs in modules.conf. Recompiling the Kernel. All to no avail.
So I've taken out the hdc=ide-scsi from lilo.
I can now mount the CDRW with mount /dev/hdc /mnmt/cdrom
and
record with
cdrecord dev=ATAPI:0,0 -v xxxxx.iso
If someone can explain why I can't get the hdc-scsi solution working it would be greatly appreciated. Now also noticed that I'm getting an entry in /etc/var/syslog about once a second. The entry is -
"can't locate module block-major-11"
It would appear from a cursory google that it may be a problem with /dev/sr and CDRW. Something to investigate.
