Hi there deafinseattle,
So, you see no unallocated HDD storage space when in Disk Management right?
You need to check how is the drive recognized by BIOS. In case it is recognized as 111 GB, then most probably there is something wrong with the drive.
In case it shows as 1 TB, then it may be a good idea to go to your MOBO's website and download the latest USB 2.0/3.0 drivers.
The best way to check out whether the issue is related to the drive or to your system is to just connect the HDD to another computer.
