It’s such a shame that what could have been a great product is plagued with problems and should have never been released until these are fixed in the firmware.
Besides frequent network disconnects which require reboots and make it highly unreliable both in the home network and as a cloud, MyCloud 3TB never ever finishes the content scan. It seems to be stuck at the last 700 or so images every single time. Rebuilding the content database never helps and never actually finishes. I also suspect this process is not letting the device go to sleep.
It’s difficult not to regret buying this product now… :-/
