I got my new Mac Mini today, and it looks like it doesn't really go to sleep fully when I put it in sleep mode. I'm using it as a media-computer basically, plugged to my TV all the time. And there are 2 external USB HDD's plugged in the back of it constantly as well. When I put the Mini to sleep, the light indicator starts pulsating for 1-2 seconds, then stays steady white for a minute. Then it starts pulsating again..so i'm under the impression that it's not really sleeping, and that the external HDD's might be the issue? And that they try to power it up? Because one of the HDD's keeps making the "boot" searching sound like it's starting up, which is weird since they should eject whenever the Mini goes to sleep. I tried doing it (ejecting) manually but it's still doing the same. I really don't feel like plugging in and out the external HDD's everytime I want to use them. Surely there must be something I can do? Because it should be blinking constantly if it's in sleep mode right?
