I have a collection of CDs, DVDs that I'd like to erase and either reuse or give away. For whatever reason I'm not able to erase them. I've followed many instructions however the word 'erase' always tends to be greyed out.
Hopefully someone can guide me?
Insert you optical disc
enter the following command to find out if the disc is erasable.
If you see a zero
then you know that the disc inserted can not be erased.
If you see a one then you can erase it.
If you enter drutil in the terminal and hit enter (to see help) you will find the word erase.
erase Erases -RW media in either quick or full mode.
drutil erase (quick | full)
So if you use the drutil discinfo command and find a few erasable discs you can bulk erase them.
Starts bulk erase mode, in which the drive will continually
erase inserted -RW media, eject it, and prompt for another
disc until terminated.
Types of erase:
quick Performs a quick erase, doing the minimal amount of
work to make the disc appear blank. This operation
typically takes only a minute or two.
full Performs a complete erase, erasing every block on the
disk. This operation is slow (on the order of 30 min-
utes) to complete.
So the command to bulk erase would be
drutil bulkerase quick
drutil bulkerase full
depending on your requirements.
If the discs don't contain personal information consider contacting Jason Scott of textiles.com, he will gladly accept them and move all the data to archive.org otherwise please dispose them in a way that doesn't harm the environment.
Hope this helps
