Jochiehans:
You might want to reconsider your firmware choice.
My personal experience is that the current FW caused too many problems so I reverted back. For instructions see

Disclaimer: I was banned from the My Cloud board for complaining about WD's lack of interest in acknowledging the problems with the current firmware.
