I'm trying to access a cdrom in Mandrake 9.0.
When I do

mount /dev/hdb /mnt/cdrom

I get

mount: special device /dev/hdb does not exist

Yes, there isn't a /dev/hdb
and there isn´t a /dev/cdrom
hdb is recognized at startup
There is an entry in /etc/fstab for it

What can I do?
Thanks

just type mount /mnt/cdrom if that doesnt work type dmesg | grep CD/DVD and find out what your cdrom is actiually called. then make a symlink to /dev/cdrom. for example if your cdom is hdc type ln -s /dev/hdc /dev/cdrom

I have two hard drives, and they are both fine, hda and hdb. But no other hdX devices exist now that I upgraded Slackware 11.0 to the 2.6 kernel. It worked fine in every way when I ran the 2.4 kernel.

"fdisk -l" lists all partitions on hda and hdb, nothing else.

dmesg |grep CD returns:
hdc: HL-DT-ST GCE-8527B, ATAPI CD/DVD-ROM drive

but as mentioned, hdcX does not exist in /dev

I do have the ide-cd driver compiled into the kernel, but I'm not quite sure how to verify that it is active and working properly. Something isn't right obviously. What am I missing?

do you have an append line to make cd burning work under the 2.4 kernel?

did you remove it when you upgraded to the 2.6 kernel?

Oh, wow. Yeah, in lilo.conf there was the line:

append="hdc=ide-scsi"

I knew the line was required for CD burning, don't know too much about what it does. Does it mean everything to do with hdc, the cdrom will be run through scsi emulation? Even simply mounting read-only? I didn't compile the kernel with any scsi drivers because the notes on ide-scsi said it's not required for burning in 2.6. I commented the append out, ran lilo, rebooted and it worked fine.

Many thanks, I never would have thought of that.

Thanks for letting me know that did it for you... I am watching another thread that I think has the same problem, ill tell him to try that too


and yes, if you have that line its always emulating the drive as scsi, as far as my understanding anyway.
