Why would a 2TB Drive say half it's space is used when it isn't.

I have a 2TB drive on Windows 2003. I copied 120GB of data onto it. It is now showing only 840GB of free space. It's like it knows it's a 2TB drive, but only 1TB is available to me. Why would this be?

The drive (Disk I) is partitioned to 2TB.

Solution 1:

The simple answer from the screenshots shown is that he hasn't selected all the files on I: when he brought up the properties. There are probably some hidden folders/files there or it could be that you don't have permissions to list all the subfolders. But basically there are 1000GB of files on the disk somewhere, not just 200GB
