That makes me think though that the price tag doesn’t belong with this product. The tag clearly says “1 piece” and also says “razor” (singular) while this product is a box of 8 replacement heads.

I once tried setting up exactly this (shared NTFS drive for games) but gave up shortly after. A lot of games would suddenly stop working between reboots, validating the games through Steam would basically redownload the whole game - just too much hassle for me.
