So, before I had a certain idea, my USB Hard Drive was read correctly as USB1 (as primary) and USB2 (as secondary). now, I figured one day,"I wonder if I can boot everything directly off the USB". So I put everything I had on my SD Card onto my Hard Drive. Sure enough, it messed it up. So I put everything back to normal and now my Hard Drive is being read as USB2 and USB3 an neither one of them are accounted for as Primary partitions. So I'm Kinda lost and confused and I don't know how to figure it out. I'm guess formatting the drive would work, but, for the sake of time, I don't want to do that until I know for sure it will work.
