Why each option
For rewritable DVD media containing sensitive information, physical destruction through shredding is the most secure and efficient disposal method. This process completely renders the data unrecoverable.
Erasing rewritable media, even through overwriting, might not be completely secure as specialized forensic tools could potentially recover residual data from the disc surface.
Shredding physically destroys the optical disc, breaking it into small, unrecoverable pieces. This method ensures that sensitive data stored on rewritable DVD media cannot be reconstructed or retrieved, making it the most secure and efficient way to sanitize such information.
