v If no error is detected, the test will loop and begin again. To stop the loop, press and hold the unload button for several seconds. When the loop ends, 0 temporarily appears in the single-character display. The drive rewinds and unloads the tape, partially ejects the cartridge, then exits maintenance mode. The solid amber status light turns off and the following message displays: Passed! Tape Unloading followed by: Cartridge Unloading In Progress then: Ultrium Tape Drive Drive Empty v If an error is detected, the status light flashes amber, a message similar to the following displays, and the tape drive posts an error code to the single-character display. ERROR! Drive/Media Error To determine the error, locate the code in Table 6 on page 39. The tape drive unloads the cartridge, exits maintenance mode, and displays the following message: Ultrium Tape Drive Drive Empty To clear the error, turn the power off, then on again. Function Code H: Test Head Function Code H performs tests to ensure that the tape drive's head and tape-carriage mechanics work correctly. The diagnostic takes approximately 10 minutes to complete and loops continually until you halt it. To halt the diagnostic, press the unload button. The diagnostic will continue to the end of its loop, then stop. The drive then exits maintenance mode. Attention: For this test, insert only a scratch (blank) data cartridge or a cartridge that may be overwritten. During the test, the drive overwrites the data on the cartridge. 1. Make sure that no cartridge is in the drive. 2. Make sure that the following message appears on the message display (you may need to turn the power off, then on again for the message to appear): Ultrium Tape Drive Drive Empty 3. Within two seconds, press the unload button 3 times. The status light becomes solid amber and the following message displays (indicating that the tape drive is in maintenance mode): Appendix B.
