I started in '78. Only in the last few years have I decided that I could see *some* justification for a GUI. Combined with a CLI, used appropriately, one can be more efficient. > However, if you're using Gnome then please have a look at System --> > Preferences --> Removable Drives and Media I just did that for another thread, as it happens.

That was MHR (Mark) that that has the problem. Mine all work as expected. > > The hd{a|b|c|d}=ide-cd kludge certainly isn't required with the CentOS > 5 2.6.18-series kernels. I last came across it with a 2.4.8-* IIRC. That was me that posted that. As I mentioned in another thread, that was a leftover from another box (probably my 2.4 kernel LFS box and/or CentOS 4.x box - I don't know if it's needed there anymore). Last time I 'sperimented w/cdrtools, IIRC, I needed it to not have to use the sg stuff.
