so, my dad kept borrowing my mom's WD Elements 1TB Hard drive that is only around to 7 months old , well my mom was getting tired of it so my dad went and bought his own, same thing, it is a WD Elements 1tb Hard Drive BUT his Bluray player will not recognize it which is weird cause it reads my mom's just fine... so whats the deal? (sorry i cant give any info on any of the Devices, i dont have any of them on hand)
