How Do Staging Technicians Use the HDD Test?
After the DNCS has been configured to support the HDD test, technicians use the
Staging Toolkit to run the HDD test utility and determine the health of the set-top
hard-disk drive. The following figure summarizes the process technicians follow.
When a DVR is returned from the field, a staging
technician presses a sequence of keys on the remote control
that turns on the Staging Toolkit.
After the Staging Toolkit is active, the technician presses
the
Last
key three times to start the HDD test utility.
The HDD test utility begins a test that determines whether
the hard drive is able to process a certain amount of data
within a time limit. While the test is in progress, the front
panel alternately flashes
hdd
and
diAg
while the HDD test
utility runs. The test takes only a few minutes to complete.
When the HDD test is complete, the result of the test is
shown on the front panel of the set-top.
Hard drives that meet performance specifications show
PASS
on the front panel display.
Hard drives that do not meet performance
specifications show a
four-digit failure code
on the
front panel display.
Note:
A code of
FF9B
indicates that the testparam.cfg file
has not been placed on the BFS HDD Test server or that the
drive failed.
After the test is complete, a technician may choose to
reformat an HDD that has failed by pressing the
key
three times. When the HDD is reformatted, all previous
recordings are erased and cannot be restored.
Technicians exit the HDD test utility by pressing the
button. When exiting, the front panel LED shows four
dashes (
– – – –
) and the set-top reboots.
