Even though I eject the drive before sleeping my MBP, I have several “drive was not ejected properly” messages (looks like about one per hour ish) on the screen when I wake my Mac next. Last time I even powered off the USB3 ExpressCard34 that the drive is plugged into, but it still woke up while the Mac was asleep! The drive sleeps itself while connected if I don’t use it for 30 minutes, so why would it wake up when the Mac is asleep?
Anyone have any idea how I can make the drive stay asleep until the Mac really does wake up??? I don’t really want to unplug it every time I slep. The drive is required almost every time I’m using the Mac.
I’m using Yosemite.
