In addition to the cdrecord examples shown earlier, you can also simply use burncd: # burncd -f /dev/acd0 -s max data cdr.iso fixate But remember one thing: don't try to mix and match accesses to /dev/acd0 and /dev/cd0. IIRC, there are (were?) some issues with using ATAPI and ATAPICAM drivers simultaneously. If you prefer to stick to ATAPICAM (recommended), use cdrecord to write to the virtual device represending the burner. Use cdrecord's -scanbus option (as root!) to find out: phenom# cdrecord -scanbus Cdrecord-Clone 2.01 (amd64-unknown-freebsd7.1) Copyright (C) 1995-2004 Jörg Schilling Using libscg version 'schily-0.8'. scsibus0: 0,0,0 0) * 0,1,0 1) 'Optiarc ' 'DVD RW AD-7203A ' '1.01' Removable CD-ROM 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) * 0,7,0 7) * This would then be on that machine: # cdrecord -v speed=8 dev=0,1,0 cdr.iso To burn to a DVD, use growisofs, using something like this: # growisofs -dvd-compat -speed=8 -Z /dev/cd0=cdr.iso Regards, -cpghost. -- Cordula's Web. http://www.cordula.ws/
