5.23 TEST UNIT READY COMMAND (00h)
The TEST UNIT READY command checks the tape drive to ensure that the unit
is ready for commands involving tape movement. If the drive has a tape loaded,
the command returns a GOOD status. Otherwise, CHECK CONDITION is
reported.
Due to power cycle, code update, and tape loaded conditions, it is possible to get
multiple check conditions on a TEST UNIT READY command.
