Here are the basic/general steps if using Windows:
Note: Use these steps at your own risk!!! Issuing the wrong command (like apt-get) via SSH can brick the My Cloud rendering it unusable!!!
Note: The screen captures used in this post are only a general generic representation. You may see slightly different screens/texts/responses.
Access the WD My Cloud using SSH
Log into the WD My Cloud Dashboard and enable SSH. Navigate to Dashboard > Settings > Network > Network Services > SSH = On.
Download PuTTY from the following link and extract the file contents to your hard drive.
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Using Windows File Explorer locate the folder where PuTTY was extracted and launch the file: PUTTY.EXE
In the PuTTY Host Name (or IP address) field input the name or IP address of your My Cloud. Leave the Port at 22. Note: You can save the settings to make it easier to access the My Cloud at a later time by hitting the Save button. Hit the Open button to start the SSH session. If you see a screen indicating a security certificate go ahead and click OK or Accept. You should then be presented with the SSH login screen.
The initial login is:
Login as: root
Password: welc0me
Note: That is a zero not an “O” in the password.
Upon first time login you may be asked to change the password. Do so, remember to write down/remember the new password as it is the password you will use for subsequent SSH login’s.
Once logged in one can then issue the two commands to turn off the scanning.
First type in the following command and hit the Enter/Return key:
cd ..
Next enter the following two commands, one at a time, hitting the Enter/Return key after each command.
/etc/init.d/wdmcserverd stop
/etc/init.d/wdphotodbmergerd stop
Note: One can copy the commands from this post and paste it into PuTTY by copying the command, then using a Mouse + Right click within the PuTTY command line interface to paste the command.
When finished entering commands one can type the command: Exit to kill the PuTTY session and exit the PuTTY program.
The two services will remain stopped until the My Cloud is rebooted or restarted. At which time those two commands will have to be run again.
There are numerous threads that discuss how to edit the startup file(s) to stop those services from running at startup or to disable those two services entirely. Here are two such threads that details how to stop those services from starting up.
