My MyCloud 3TB drive didn’t spin down when I first installed it and I attributed that to it indexing the files I had backed up. After that, I determined that it would indeed sleep, but only if the cloud feature was disabled.
For the last few weeks though, it spins 24//7 and does give off a little bit of heat. I continue to have the cloud feature disabled and overnights I have shutdown the 2 laptops that connect to it. Still it spins all night without any traffic.
This latest firmware left out the shutdown functionality and I have to wonder whether the drive sleeping functionality has been hampered as well. How can it not spin down without anything addressing it?
