I’ve found the same issue on my WD-Mycloud after the blue LED being off for about 2 Years (i was using DSM).
I’ve found the problem is caused by HW so the only choice is replacing it by a rarely used color like Green (which makes more sense by the way)
there are 2 solutions to replace the off LED by green.
1: (Easy)
ssh to the Mycloud.
#nano ~/.bashrc
add below text to the end of the file, then CTRL+X, then Y and then Enter to save the file:
echo green > /sys/class/leds/system_led/color
this way, when the HDD Starts, after a few seconds of being off, the green LED will remain on.
2:(The accurate way):
SSH to mycloud
#nano /usr/local/sbin/ledConfig.sh
Then replace all “Blue” words with “green” for below line:(i’ve already replaced “blue” with “green”)
LED_NORMAL_COLOR=( “green” “green” “green” “green” “green” “green” “green” “off” “green” “green” “green” “green” “green” “green” “green” “white” “white”)
then CTRL+X, then Y and then Enter to save the file.
To verify, you can reboot the HDD through the webui.
This way the system will simply replace the blue with green.
Note:Possible colors:
white
yellow
blue
green
red
Updated and easier version of the workaround:
1:Login to your mycloud webUI entering its IP address in a browser
2:Go to setting> Network and turn on the SSH. default password will be welc0me
3:Use a simple terminal emulator app like putty to ssh to your myCloud using its IP address.
4:You should see similar prompt after a successful login: WDMyCloud:~#
5:Enter below 3 commands, you should get no output or error.
WDMyCloud:~# cp /usr/local/sbin/ledConfig.sh /usr/local/sbin/ledConfig.sh.orig
WDMyCloud:~# sed -i "s/blue/green/g" /usr/local/sbin/ledConfig.sh
WDMyCloud:~# exit
6:To test it, unplug the network cable until it starts to blink, then connect it back (Thanks [cpt_paranoia]).The green led will turn on.
7: Go back to webUI and disable SSH for security purposes.
note: Remember after every firmware upgrade, you need to redo this procedure.
