The TEST UNIT READY command provides a means to check if the drive is ready. This is not a request for a
self-test. If the drive is able to accept an appropriate medium-access command without returning a CHECK
CONDITION, this command will return a GOOD status. Otherwise, a CHECK CONDITION will be reported and the
sense key will be NOT READY.
