I just wonder does anyone meet the similar problem of mine. I connected an usb3.0 disk to WD My Cloud and tried to copy some files from that disk to WD My Cloud from the network folders on Windows. During the transfer, the WD My Cloud stopped working and I cannot access the shared folders or open the My Cloud Panel anymore. Only after I unplug the power cable can I make it work again.
Is it a defect related to the USB3.0 port?
