I bought a new hard drive around 8 months ago. It's a Seagate ST2000DL003 with 2 TB of space. When I right click on the C Drive, it says 1.1 TB are being used, but when I actually go into the hard drive and select everything there (including the hidden and system files), it says I have only used 200 GB. I searched for why this could be happening, and the common answer I got was that my hard drive was being consumed by system restore points. Makes sense, or it would if I had that feature turned on. Even though it doesn't make sense, I did the command for checking your shadow copies, and as I thought, I don't have any, or at least it didn't say I had any.
I am running 64 bit Vista, and have an HP A6757c computer. I have only 1 partition and regularly defrag it. I don't run error check very often, but running it did not help.
What is causing this, and how can I fix it?
