Function code H: Test head

Approximate Run Time = 10 minutes per loop
Total Number of Loops = 10
Function code
tape-carriage mechanics work correctly.
Once you begin this test, the diagnostic begins the loop sequence. Time the first
loop by pressing the Unload button once to stop the diagnostic after the
completion of the first loop, then record the time it takes for the test to complete.
Compare the recorded time with the "Approximate Run Time" above. If the test
runs successfully but the execution time is significantly longer than the
"Approximate Run Time", run "Function code F: Write performance test" on page
36. If the Write Performance Test fails, replace the media and exit Maintenance
mode.
Press the Unload button to stop the diagnostic and exit Maintenance mode.
Pressing the Unload button once will abort the test at the end of the current test
loop. Pressing the Unload button twice will abort the test immediately. Wait for the
drive to rewind the tape and unload the cartridge.
Attention: For this test, insert only a scratch (blank) data cartridge or a cartridge
that can be overwritten. During the test, the drive overwrites the data on the
cartridge.
Note: If you inserted an invalid tape cartridge (e.g., Ultrium 3 or WORM tape
cartridge), error code
write-protected cartridge, or the media has read-only compatibility (e.g., Ultrium 4
tape cartridge), error code
unloads the cartridge and exits Maintenance mode after the cartridge is removed.
To execute Function code H: Test head, complete the following steps:
1. Put the drive in Maintenance mode. For instructions, see "Entering
Maintenance mode" on page 27.
2. Press the Unload button once per second until
cycle past the desired code, press the Unload button once per second until the
code reappears.)
3. Press and hold the Unload button for 3 or more seconds, then release it to
select the function. The SCD changes to a flashing
4. Insert a scratch (blank) data cartridge. The SCD changes to a flashing

v If no error is detected, the diagnostic will loop and begin again. To stop the
loop, press the Unload button for one second and release. When the
diagnostic ends,
