How can use wodim to erase a cd/dvd?
A rewriteable cd/dvd must be “blanked” before new stuff can be written to it. CDs are not like floppies or USB drives, you cannot simply add files to an already written CD. The entire disk must be erased in order for new content to be written. To blank a disk: • put the disk in the appropriate drive but do not close the drive door • execute the following command: @: wodim blank=fast On a good day, the drive should now close by itself and the blanking process should start.9.6 On a not so good day, wodim will gag on the above command. To make wodim try harder you can add the -force flag.
