This locker contains software that may be useful with CDR and CDRW drives. Bug reports may be sent to bug-cdrecord@mit.edu. How to record a data CD: 0) Make an ISO 9660 filesystem containing the data that you want to record: add cdrecord mkisofs -J -r -o /tmp/ where is the name of the file in which the ISO 9660 filesystem will be stored, and is the name of the directory that *contains* all the files and directories that will be written to the CD. ( itself will not be written to the CD; only the files and directories within it will be written.) The -r option generates SUSP and RR records using the Rock Ridge protocol and sets file ownership and modes to more useful values, and the -J option generates Joliet directory records; you will probably want to use both of these options. 1) Become root. If the machine is a private one, you'll have to ask the administrator, but in a public cluster, you can run tellme root to find out the root password, and then you can 'su' to become root. 2) Burn the ISO image to CD. On an public Athena workstation, you may run: cdrecord -v speed=8 /tmp/ If you are using a private workstation with more than one CD/DVD drive, you may have to specify the proper device to the cdrecord command, by running something like: cdrecord dev=/dev/hdd -v speed=8 /tmp/ Consult your workstation's administrator if you are unsure of the proper device string for your CD-RW drive. 3) To mount the cdrom to verify it, run: mount /dev/cdrom cd /mnt/cdrom ls 4) When you're done verifying it, you need to exit the cdrom directory and umount the cdrom: cd / umount /dev/cdrom
