Ensure that the drive is unloaded. Then, press and hold the Unload button until the Ready LED begins flashing rapidly
(approximately 6 seconds).

Note: While in Service mode, the drive does not accept commands from the server.

Scroll through the Service Functions

While in Service mode, press the Unload button once per second to increment the Service Functions by one. When you

Table 1. Service Mode

Press the Unload button once per second until you have scrolled through all Service mode selections. Service mode is
exited when all LEDs are off except for Ready LED which is on solid. The drive will exit Service mode if there is no Unload
button activity for 15 seconds. See

Table 1. Service Mode

for more information.

Force a drive dump

Attention: If the drive detects a permanent error, it automatically forces a drive dump (also known as a save of the
firmware trace). Captured dump data is placed in drive RAM. If you force a drive dump, the existing dump will be
overwritten and it will be lost. After you force a drive dump, do not turn off the power to the drive or you may lose the
dump data. To permanently save a dump to non volatile memory, see

Executing Service Function 4: Copy dump to flash

. A

dump that is saved to flash memory will persist thru a drive power cycle.

To force a dump, choose one of the following procedures:

l

If the drive is in Service mode, scroll to and select Service Function 2 (see

Executing Service Function 2: Force

dump

).

l

If the drive is in Operation mode, press and hold the Unload button for 12 seconds.
