Standard Self-Test

With a tape

inserted:

If Self-Test = 1 and UntOffl = 0, a test is performed that does not affect the

contents of the tape. This test is a more extensive set of the tests carried out at

power-on.
If UntOffl = 1, the tape contents can be overwritten and will be undefined after

the test. A user can re-use the tape after the test.

With no tape in the

drive:

The same self-test will be executed regardless of the setting of UntOffl.
The results of any self-test (power on or not) can be determined by reading the

Self-Test diagnostic page before executing a diagnostic (which will overwrite

the result).
