[nflug] CD/DVD drives not working in linux

[David J. Andruczyk]

Seen that before.  easy fix.

change the /dev/scdx values to /dev/srx . i.e. /dev/scd0 = /dev/sr0
make sure the "sr_mod" and "cdrom" modules are loaded in the kernel
(lsmod |grep sr_mod ),  If they aren't modprobe them, and add them to
/etc/modules.autoload.d/kernel-2.6 so they get loaded on next boot
automagically

I assuming you have udev setup correctly as well, right?,  run "mount"
and you should see a line like:

udev on /dev type tmpfs (rw,nosuid)
