I have an iMac MID 2011 with Mountain Lion 10.8.2.
I've connected an external HD : Samsung G3 TB1.5 via a USB 2 .
When my iMac goes to Sleep (Manually by me) The HD sometimes turning OFF (No Light) but sometimes stays in Standby mode .
Can someone explain me this issue ?
As I have still warranty on my HD if it's with problems ..
