Hi, I'm a newbie to this but plugged in an external usb drive and it came up with a choice of whether I wanted to use windows or mac to connect the drive. I chose Windows but didn't want it to default to that every time. For some reason it has now done that (even though I didn't hold down the shift key). I would like to be able to access this external usb drive in mac now but don't know how to get it to 'forget' it's default when I plug it in - how do I do this? Thanks
