HPR3986: Optical media is not dead

Brought up by Klaatu on GnuWorldOrder.info

Media size

4.7Gb DVD - Actual capacity: 4.377Gb

What is the actual storage capacity of a dvd disc

A disc with a 25GB capacity is the equivalent of 23.28 gigabytes Normally rated at 50GB, in practice they can record about 46.57GB of data

What is the maximum capacity of a blu ray disc

Generate ISO image from directory

genisoimage -U -R -allow-lowercase -allow-multidot -o mydvd.iso "$1"

Alternative is mkisofs

-U Allows "untranslated" filenames, completely violating the ISO9660 standards described above. Enables the following flags: -d -l -N -allow-leading-dots -relaxed-filenames -allow-lowercase -allow-multidot -no-iso-translate. Allows more than one `.' character in the filename, as well as mixed-case filenames. This is useful on HP-UX, where the built-in cdfs filesystem does not recognize any extensions. Use with extreme caution. -R Generate SUSP and RR records using the Rock Ridge protocol to further describe the files on the ISO9660 filesystem. [Wikipedia - ISO 9660](https://en.wikipedia.org/wiki/ISO_9660#SUSP "Wikipedia - ISO 9660")

Corrected command

genisoimage -R -o mydvd.iso "$1"

Burning data to a DVD or Blu-ray

Note:

Make sure that the medium is not mounted when you begin to write to it. Mounting may happen automatically if the medium contains a readable file system. In the best case, it will prevent the burn programs from using the burner device. In the worst case, there will be misburns because read operations disturbed the drive. So if in doubt, do:

umount /dev/sr0

growisofs has a small bug with blank BD-R media. It issues an error message after the burning is complete. Programs like k3b then believe the whole burn run failed. To prevent this, either format the blank BD-R by dvd+rw-format /dev/sr0 before submitting it to growisofs or use growisofs option
