Abstract
In an approach, a processor determines that an inactive data area is present at end-of-tape (EOT) of a tape. A processor, responsive to determining that the inactive data area is present at EOT, securely erases the inactive data area that is present at EOT by overwriting data located at the inactive data area with different data.
