View Full Version : changing cdrom device order

26th May 2008, 08:32 PM
I have two cdrom drives,
1. is old cd-rom
2. is the new dvd+rw drive I use

the problem is that for some reason fedora 9 set the old one as the primary one, whilst fedora 8 (on the same machine) recognizes dvd+rw drive as the primary one. Is there a way to change the cdrom order in fedora 9?

Set the symlinks in /etc/udev/rules.d/70-persistent-cd.rules

This is usually set in the bios, determned by the cabling and jumpers on the CD/DVD drives.

If convenient, the easiest way is to probably change the cabling, so that the connector going to the old one now goes to the new one. However, you might have to change the jumpers on the back to make sure that neither is set for master and/or slave. Newer drives have another jumper position (which is what is usually the default) C/S for cable select. This means the drive becomes master or slave depending upon the cable.

thanks for help :)

edit: udev is the right choice here, changing drive order physically isn't required
