"/dev/cdrom is not a valid block device" error
 

I recently upgraded to FC2 from FC1. I tried to mount a cdrom, but I keep getting this error. I've tried serveral different cdroms, none of which work. I did a search here and found similar problems, but none of the fixes that people gave worked for me....:confused:

ls -l /dev/cdrom gives:
lrwxrwxrwx 1 root root 8 Jun 3 10:40 /dev/cdrom -> /dev/hdd
(which is correct according to the hardware browser)

The line for the cdrom in fstab is:
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

I also tried the "depmod -ae" trick, but that didn't do anything.

I also get the error when i try to "mount /dev/hdd /mnt/cdrom".

Any ideas? :scratch:

what about if you only do

mount /mnt/cdrom

that should mount the drive if it's mentioned in fstab..altough I doubt this, if you can't mount it with a normal command either.

I found the error. There was a line in grub...something like hdd = ide-sdc0 or somesuch. Got rid of the line, and it worked.

Yes, the new 2.6 kernel does not need append="hdb=ide-scsi" when starting the kernel for cd/dvd-burners. It supports native comunication over ide without SCSI-emulation.

Hello,

I recently upgraded to kernel 2.6.5 on my Slackware box.
I'm running a CDrom Drive at /dev/cdrom and a CD-RW at (not my choice) /dev/hdd. Both are ide.

The drive used to work in kernel 2.4 but now I also get the error message you mention. Anyway, I thought it might be something to do with the ide-scsi line in my lilo.conf file as kernel 2.6 doesnt need SCSI emulation.

So thanks for confirming my suspicions. I will take it out and see what happens. I compiled to 2.6.5, got kde 3.2.2 and open office 1.1.1, got java, flash, real player, firefox etc, working so I am really pleased with this computer! All this on an 850mhz PC :-) All the hardware is going great too (except the cd-rw...)

Now to configure samba or lisa and remote desktop connections.......
