Note: Every piece of Free CD writing software available for Unix uses either cdrecord or cdrdao for it's back end work. Similarly, all CD rippers use cdparanoia or cdda2wav. cdparanoia is the best choice around, unless you're sure the disk is perfectly clean. Copying a cd with cdparanoia and cdrecord is pretty easy, too. Rip the CD into individual wavs, thusly: 'cdparanoia -Bzv', then burn it like so: 'cdrecord speed=blah device=meh -audio track*.wav'. Let it churn for a while, and it's all done. > This (and many other) CD burner programs are happiest when you run as > root - running as a user is possible, but requires more configuration. This is true, and it's not just about accessing the devices (it's trivial to setup permissions to let users access the generic SCSI devices). cdrecord also uses it's root permissions to give itself real time priority (so gets as much CPU time as it wants RIGHT AWAY), and to mark the memory it's using as unswappable (so that it doesn't get swapped out and ruin a CD). I'm not sure how important these are on modern systems, but they were surely put in there for a reason. > If you're not able to access your CD burner and/or CDROM drive, make > sure you have SCSI emulation set up. Also, don't forget to include SCSI CD-ROM support as a *module*, so you can mount CDs in your burner. It's called sr_mod if you already have it. -- Rob Weir <rweir@ertius.org> http://ertius.org/
