Test 15
Test 9
Before starting this test, all tape reels must be unloaded.
Diagnostic Test 1 (General Check)
A scratch tape is needed for this test.
This test performs a complete tape unit check. It runs all power-on tests, then loads
a tape and checks out all sensors. It then runs the tests in the multiprocessor,
sensor, and wellness sequences.
The Sequence:

Diagnostic Test 2 (Wellness Test)
A CE tape is needed for this test.
This test checks out the general read/write ability of the drive. The sequence
includes the tests necessary to write a 6250 density tape, rewind and read the tape,
rewind, write the tape in 1600 density, rewind and read the 1600 density tape, then
rewind.
During the write process, the Enter key causes the write to end early so that the
complete tape is not written. The following read pass will only read as far as the
write pass had written.
