The drive is a white label drive and has 1tb of space on it. It can be see nin the BIOS and the device manager but when I try to turn it online in disk management, it cannot be formatted or turned online due to an "I/O device error". I've used it before when I had windows 7 but recently upgraded to windows 10 and chose to not keep any files. Disk manager says it's a recovery partition with 450mb with no file system.
