ERROR_END_OF_MEDIA

the physical end of the tape has been reached.

ERROR_END_OF_MEDIA means that a tape operation reached the physical end of the currently loaded medium.

Where the result appears

  • sequential backup and archival systems.
  • tape restore, verify, copy, or positioning operations.
  • multi-volume backup sets.
  • legacy removable sequential media workflows.

Typical causes

  • the requested read or write extends beyond usable tape length.
  • the current volume is full and the backup set expects another medium.
  • positioning moved to the physical end rather than a logical file boundary.
  • capacity assumptions do not match the loaded cartridge or drive mode.

What to collect

  • drive and media identifiers, capacity estimate, partition, block size, and position.
  • operation type, requested length, bytes completed, and backup-set sequence.
  • drive sense data and tape-library events.
  • whether spanning to another volume is configured and which medium is expected next.

Handling and recovery

Finalize the current volume according to the backup format and request the correct next medium when spanning is supported. Do not overwrite or rewind automatically unless the media-management policy explicitly authorizes it. For restore, verify that the expected volume sequence is complete.

Common misinterpretation

Physical end of media is different from an application filemark or setmark. It reflects medium capacity, not merely a logical separator.
