Function Code F — Write Performance Test

Causes the tape drive to perform tests to ensure that the drive can read from and write to tape. This diagnostic performs 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 as comprehensive a

test and is not recommended for isolating errors between the drive and the media.

Attention: Data on the suspect tape will be overwritten.

1. Ensure that there is no cartridge in the drive.

2. Press the eject button three times within an interval of 2 seconds. The status light becomes solid amber, which means that the drive is in

maintenance mode.

3. Press the eject button once per second until

it redisplays.

4. To select the function, press and hold the eject button for 3 seconds. After you select the function,

flashes and the test begins.

If no error is detected, the test begins again and runs for a maximum of ten times. Each loop takes approximately 3 minutes to run. After the

tenth 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 the eject button 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 terminate the test that is running, press the eject button twice. The tape drive rewinds, unloads the

cartridge, and exits maintenance mode.

Function Code H — Test Head

Causes the tape drive to perform the Head Resistance Measurements test and a Write/Read test (on the center of the tape). The drive runs these tests to

ensure that the tape drive's head and tape-carriage mechanics are working correctly. The tape drive takes approximately 10 minutes to run the test.

1. Ensure that there is no cartridge in the drive.

2. Press the eject button three times within an interval of 2 seconds. The status light becomes solid amber, which means that the drive is in

maintenance mode.

3. Press the eject button once per second until

it redisplays.

4. To select the function, press and hold the eject button for 3 seconds. After you select the function,

If no error is detected, the test begins again and runs for a maximum of ten times. Each loop takes approximately 10 minutes to run. After the

tenth loop, the test stops and the drive automatically exits maintenance mode.

If an error is detected, the tape drive displays "5", unloads the tape cartridge, and exits maintenance mode.

To halt the diagnostic at the end of the current 10-minute test loop, press the eject button 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 terminate the test that is running, press the eject button twice. The tape drive then rewinds, unloads

the cartridge, and exits maintenance mode.

Function Code J - Fast Read/Write Test

Approximate Run Time = 5 minutes

Total Number of Loops = 10

Function Code

performs tests to ensure that the drive can read from and write to tape.

The diagnostic loops ten times. Press the eject button to stop the diagnostic and exit maintenance mode. Pressing the eject button once will abort the test

at the end of the current test loop. Pressing the eject button twice will abort the test immediately.

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. Ensure that there is no cartridge in the drive.

2. Press the eject button three times within an interval of 2 seconds. The status light becomes solid amber, which means that the drive is in

maintenance mode.
