I have a setup here which has always worked for me in the past where I could use genisofs to build an ISO image and that still works great. But alas wodim is another story. I always used in the past up to about a year ago with no problems. Now I get errors that cannot find any devices. I will add a script listing to the bottom of this message when I'm through. I'm using a 3.5 kernel on Arch Linux and this is an HP laptop with a typical CD burner. internal. It has been defined as /dev/sr0 in the past and actually, CD's and DVD's read fine in this device right now. So, what could be missing here? ----- Begin wodim session ----- Script started on Fri 05 Oct 2012 04:05:12 AM PDT steve at linlap ~$ wodim --devices wodim: No such file or directory.
