Attention When you perform this test, data on the suspect tape will be overwritten. 1. Place the drive in maintenance mode. For instructions, see "Entering Maintenance Mode" on page 15. 2. Press the Unload Button once per second until E appears in the SCD. (If you cycle past the desired code, press the Unload Button once per second until the code reappears.) 3. Press and hold the Unload Button for three or more seconds, then release it to select the function. The SCD changes to a flashing C . 4. Ensure that the write-protect switch on the suspect cartridge is off, then insert the cartridge (or the tape drive exits maintenance mode). The SCD changes to E . The tape drive runs the tests. v If no error is detected, the test will loop and begin again. To stop the loop, press the Unload Button for one second and release. When the loop ends, 0 temporarily appears in the SCD. The drive rewinds the tape, unloads the cartridge, and exits maintenance mode. v If an error is detected the test stops, 6 or 7 appears in the SCD (another code could appear). To determine the error, locate 6 or 7 in Table 9 on page 45. The drive unloads the tape cartridge, exits maintenance mode. To clear the error, turn the power off, then on again. Function Code F: Fast Read/Write Test Approximate Run Time = 5 minutes Total Number of Loops = 10 Function Code F performs tests to ensure that the drive can read from and write to tape. The diagnostic loops ten times. To stop the diagnostic and exit maintenance mode, press the Unload Button once to abort the test. 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. Place the drive in maintenance mode. For instructions, see "Entering Maintenance Mode" on page 15. 2. Press the Unload Button once per second until F appears in the SCD. (If you cycle past the desired code, press the Unload Button once per second until the code reappears.) Operating the Drive 23
