Caution: 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.
Note: If you inserted an invalid tape cartridge (e.g. Gen2 or WORM
media), error code J or 7 appears in the SCD. If you inserted a
write-protected cartridge, or the media has read-only
compatibility (e.g., Gen3 media), error code P appears in the
SCD. In either case, the tape drive unloads the cartridge and
exits Maintenance Mode after the cartridge is removed.
1 Place the drive in Maintenance Mode. For instructions, see Entering
Maintenance Mode on page 45.
2 Press the Unload Button once per second until H 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 Insert a scratch (blank) data cartridge. The SCD changes to a
flashing H. The tape drive runs the tests.
• 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, 0 temporarily appears in the
SCD, and the tape drive exits Maintenance Mode.
• If an error is detected, the Fault light flashes and the drive posts
an error code to the SCD. To determine the error, locate the
code in Appendix A, Error Codes and Messages . To clear the
error either turn the power off and then on again, or reboot the
drive by pressing and holding the Unload Button for 10
seconds.
Function Code J: Fast
Read/Write Test
Approximate Run Time = 7 minutes per loop
Total Number of Loops = 10
Function Code J performs tests to ensure that the drive can read from
and write to tape.
