The sleep mode is a common complaint with many threads discussing it. One needs to monitor the My Cloud over time to see if the unit actually goes to sleep rather than what it does for many; goes to sleep for 7-10 minutes then wakes up. The My Cloud should go to sleep after roughly 10 minutes of inactivity, the problem is that after it goes to sleep it will often wake up every 7 to 8 minutes due to services being run in the background.
