Function Code F - Write Performance Test
Causes the tape drive to complete tests to ensure that the drive can read from and write to tape. This
diagnostic completes fewer tests than the Run Tape Drive Diagnostics test (Function Code 1). The tape drive
takes approximately 3 minutes to run the test. The Fast Read/Write Test is not a comprehensive a test and is
not recommended for isolating errors between the drive and the media.
Attention: Data on the suspect tape is overwritten.
Note: If you inserted an invalid tape cartridge (see "Data cartridges" on page 21), error code
in the SCD. If you inserted a write-protected cartridge, or the media has read-only compatibility (see Table 5
on page 21), error code
Maintenance mode after the cartridge is removed.
1. Ensure that there is no cartridge in the drive.
2. Press Eject 3 times within an interval of 2 seconds. The fault LED becomes solid amber, which means that
the drive is in maintenance mode.
3. Press Eject once per second until

tape drive exits maintenance mode). After you insert the cartridge,
• If no error is detected, the test begins again and runs for a maximum of 10 times. Each loop takes
approximately 3 minutes to run. After the 10th loop, the test stops and the drive automatically exits
maintenance mode.
• If an error is detected, the tape drive displays an error code. Once the cartridge is manually ejected and
removed, the tape drive exits maintenance mode.
• To halt the diagnostic at the end of the current 3-minute test loop, press Eject once. The drive
acknowledges the request by slowing the length of time that the currently displayed character flashes on
the single-character display (from twice per second to once per second.) The diagnostic continues to the
end of its loop and then stops. The tape drive then rewinds, unloads the cartridge, and exits maintenance
mode.
• To halt the diagnostic immediately and stop the test that is running, press Eject twice. The tape drive
rewinds, unloads the cartridge, and exits maintenance mode.
