You are supoused to unmount the volume. Try it. umount /dev/cdrom ? Make sure that is it not in use, then unload it.
New versions of gnome and so have the option to right click the loaded device and then to unmount.

It should never hang. Does it hang with the floppy when removed?

1. When I did umount /dev/cdrom it says - "umount: /dev/hdc is not mounted (according to mtab)"
2. Yes


You are trying to unmount a /dev/hdc? hdc is an IDE Hard Drive, you have a CD burner, I would doubt that it is /de/hdc.
type mount and that will tell you what is mounted, try umount /dev/cdrom. You need the hardware unloaded.

Try /etc/init.d/hotplug stop and unplugg the hardware. See if that hangs the PC.

Figure out on how to unload the module, then you will need to get us more info here for this problem to be looked...

anyone has more suggestions?
