I've got a buddy's rig that's having issues with a 3tb HDD. It detects all 3tb in the bios so there's no issues there. What we're trying to do is get it into two 1.5 partitions and instead he's got three (1.47tb, 746gb,583gb). None of which are loaded with an OS, strictly for storage. Any ideas on how to get it down to two partitions guys?
