Due to some type of reading with windows it won't read a terabyte, or more, from the get go. You will have to format it, or create a partition.

To do so you can either type, diskmgmt.msc, into the command prompt. Or it should be under control panel, system and security, administrative tools, and create and format hard disk partitions.

It should show up as an unallocated drive or something. You probably have to right click the partition and options should show up. I can't remember which option it would be though.
