Checking the Busy Light
Models 330S and 660S
When the rewritable optical disk drive power is switched
on, the rewritable optical disk drive automatically performs
a self-test. The rewritable optical busy light shows the
status of the rewritable optical disk drive during the
self-test and during activity with the host computer. The
rewritable optical busy light is an amber light-emitting
diode (LED) located on the front panel of the rewritable
optical disk drive (see Figure 3-3).
The rewritable optical busy light displays the following
sequence when the mass storage system power is switched
on:
1. ON
The rewritable optical busy light goes on when the
self-test sequence starts. If there is a rewritable optical
disk in the disk port, read/write tests are performed on
the rewritable optical disk and the rewritable optical
busy light stays on until the self-test sequence has---
completed. If there is no rewritable optical disk in the
disk port, the rewritable optical busy light stays on until
the self-test has completed.
2. OFF
The rewritable optical busy light goes off when the
self-test has completed.
After the self-test successfully completes, the rewritable
optical busy light shows rewritable optical disk drive
activity with the host, and will appear to flash randomly. If
the rewritable optical busy light is off, the rewritable optical
disk drive is idle.
