Ok so i did a clean install on my PC and for some reason my PC is reading my external hard drive as unallocated. It reads perfect on our other computers and on other media devices, but on says unallocated on my PC. What should i do to get it back? formatting is not an option because I have close to 700 gigs of stuff on it and can't lose it. If i right click it says i can do some stuff to it but i don not know what option to choose.
