I have a brand new seagate 2 tb hard drive (internal). I am trying to put it in a new computer to run windows (that will be the only hard drive in the rig). It only shows that is has 3.9gb of space which is not enought to install windows. So I decided to plug this hard drive into my other desktop computer to see if it will do the same thing. In the Disk Management tab (under administrative tools) it automatically asks me to initialize the disk as MBR or GPT. When I tried either of these, It came up with a message "The request could not be performed because of an I/O device error". Help Please and Thanks.
