Windows 7 seems to randomly eject an external drive. I've deactivated the usb sleep mode but it still happens. Not sure if this information is useful but this only seems to happen while I'm running a game which is installed on the external drive. I'm wondering if this could be related to a higher power needed while gaming. My iMac has usb 3 though, so it couldn't be a problem, right? Any idea what else could cause this? Thanks!
