Red LED Light comes on during boot, then LED shuts off and thats it folks

[DianneB]

This LED issue has infected by 2TB drive too. Mine only has red steady on during boot then turns off, no other light is on after that.  A full complete factory reset did NOT solve the issue.  WD MY BOOK LIVE 2TB.  Latest Firmware.  Red comes on during boot, then LED shuts off and thats it folks.  Data accessability does not appear to be an issue and diagnostic tests pass.

cat /usr/local/nas/led_color 

off

Write green to that device and see what happens.

echo green>/usr/local/nas/led_color

[DianneB]

Already tried that.  Nothing happened.

Do any of these work?

echo red > /sys/class/leds/a3g_led/color
echo yellow > /sys/class/leds/a3g_led/color
echo blue > /sys/class/leds/a3g_led/color
echo green > /sys/class/leds/a3g_led/color

 Also . . .

echo yes > /sys/class/leds/a3g_led/blink

 . . . and . . .

echo no > /sys/class/leds/a3g_led/blink

 Maybe there is a hardware fault or a fault with the device driver handling the LED?
