How To's: DVD and CD Writing
This is a brief, working primier to DVD writting under Linux.
DVD (-) and regular plain ole CD's.
- Put all your files in one location. (I assume you can get here w/o help.)
- Make the image (iso from here on out) of the files.
mkisofs -J -r -o $outputname $yourdir/
- So now you have an iso (image source object, or whatever) with Joliet and rockridge file extentions. This means windows and unix should be able to read this no problem.
- Now we write. I usually check and double check the filesize here. I'll include exact numbers later.
For cd's (Anything smaller than 700 MB):
cdrecord -v dev=0,0,0 speed=8 -dao -data $outputnameFor DVD's (anything larger than 700 MB):
dvdrecord -v dev=0,0,0 speed=2 -dao -data $outputname
- Also, be it known that dvdrecord will work fine for cd's.
- The same command, with slightly different arguments is used for erasing both DVD-rw's and CD-rw's. From here on
out, I'm just gonna use "cdrecord", please use which ever is appropriate to the task.
cdrecord -v dev=0,0,0 speed=8 blank=$varIf you want to blank the whole X-RW, use "all", else, "fast" usually works. If the rewritable media is giving problems, by all means use "all".
- Writting a re-writable media is no different than a regular write.
- After you've written the disk, CHECK IT.
DVD (+) Media... Slightly different..
This is geared toward writing with the new ide-cd style options. The difference is, the new Linux 2.6.7 enabled machines don't need to use the old SCSI Emulation formats. I assume the magic happens at the kernel level. The difference is:
- To do
cdrecord -scanbusYou actually need to do:
- Or you can just use:
cdrecord -v dev=/dev/hdd speed=8 -dao -data $blah
DVD+R media must be initialized. This is actually pretty simple. We use the dvd+rw-tools debian packages.
medea:/home# dvd+rw-format /dev/hdd
Writing to the new initialized +RWWrite contents of a directory(or file) to a newly initialized DVD+RW
medea:/home# growisofs -Z /dev/scd1=image.iso
Or you can mesh the two steps, and eliminate the mkisofs intermediate step. (Nice!)
medea:/home/# growisofs -Z /dev/hdd -R -J /home/blah/Backups/
More multi session madness coming soon. I don't think I've ever actually used multisession. It just always seemed like a Bad Idea. :)
