I've been using cdrecord to burn CD's and DVD's forever.
I am running FC6, from a clean install. Look at this:
cdrecord --scanbus
cdrecord: For possible targets try 'cdrecord -scanbus'.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
cdrecord -scanbus won't work either, tries to find a file named -scanbus.

Huh? Should print out the simulated scsi bus location, like 0,1,0, which is what it is.

It won't burn a thing, either, with cryptic error messages that I don't understand. Normally dev=ATA:0,1,0 works fine, but not now.

Oddly, Nero for Linux, and Mondoarchive burn DVD's from .iso files just fine, but I have no idea how they are doing it.

What has happened? I'm clueless.
Thanks, Ray

I dunno. Check /etc/cdrecord.conf for wierdness. Also try running as root, or even with 'selinux=0' on the kernel command line.

The other apps may be using dvdauthor or growisofs instead of cdrecord.

Thanks, /etc/cdrecord.conf looks quite sane to me. Also, the behaviour described occurs as root, and I have selinux disabled. A real mystery, as this worked fine before, and now, sudden, unexplained failure. I removed and replaced the app with no joy. I just don't even know where to start looking.
Any ideas?

I have found problems when writing CD iso's to cd or copying CD's. it appears there was a fork of cdrtools and if you have upgraded then you may have a buggy version of cdrtools. I run Slackware 12. I removed the cdrtools package that came with Slackware 12 and installed the packages that came with Slackware 11. It works now.

Have a look at :
