Been using the 4tb MyCloud little white box for about a year now. Lots of updates, resets, factory reboots and time spent wondering how anything could be so slow.
Gave up this week - factory reset - turned everything off - added some shares and got a copy of SyncBack. Unbounded joy is mine. it’s a great little NAS - too bad it is saddled with Smartware.
Don’t fool around - just dump Smartware and use the box as a NAS.
I wish I had a those hours back.
