Ok i goofed somewhere, my PC treats any S-ATA device like its Plug-and-Play so even my System Hard Drive appears in the 'safely remove hardware' window.
Thing is, my PC auto sets a default action for every PnP device, and i cant change what it set for my HDDs, so when i go to My Computer and double click my C or F drives, they dont Open, i have to Right-Click and select 'Open' or 'Explore'
How can i restore double-click? Its really annoying me now.
