Erasing a Rewritable Disc
If you are using CD-RW, DVD-RW, DVD+RW, and DVD-RAM media, you can erase the entire contents of a disc and re-record to it.
Caution: If you have copied extremely sensitive data to a rewritable disc (such as private personal information), you may want to destroy the disc rather than choose the option of erasing it and re-recording over the data.
To erase a rewritable disc:
1Insert the disc into the recorder.
2 Choose Recorder > Erase.
A dialog appears, prompting you to confirm that you want to erase this disc:
If you want to erase the disc quickly and you do not mind that this disc will be usable only by Toast (or Jam), click Quick Erase.
If you want to erase the disc so that it can be used anywhere, click Erase.
3 To erase the disc, click OK.
If you confirm, Toast displays a progress bar while erasing the disc.
