Tape Directory Invalid
- B’0’: Indicates the Tape Directory is valid
- B’1’: Indicates the Tape Directory is invalid
Note:
This field may not be valid if the drive is not ready or when the sense data is associated with a CHECK
CONDITION status (contingent allegiance or autosense condition). The Request Sense command should be
used to return unsolicited sense to insure the field is valid. An invalid Tape Directory will be automatically
rebuilt using a performance optimized method during any space or locate operation. There is no need to fully
read the media for directory rebuilding.
