Correction. I cannot read a CD in this Storix drive. I thought I had recently, but not. I used this drive all the time on this system when it had Centos 4.x installed. Probably the only 4.x system left around here is a Trixbox 2.2.10 install. I will have to test on that tomorrow. But no gnome installed, so it will have to be all command line....
