I just purchased a Seagate 2Tb usb 3 hard drive, but Windows 7 will not see it at all not in Disc Management or win explorer. My Asus motherboard supports usb 3 and sees the drive in the uefi bios. I plugged in a 500Gb hard drive and an 8GB thumb drive into the same socket and they both work fine. All my drivers are up to date so does this mean I must upgrade to windows 10 to make the drive work. I'd be grateful for any advice. Gampsey
