A "6GB Hardrive" with only one partition on the drive taking up all the space, NTFS format.

2.35GB of files, folders, etc. *This includes the operating files, and hidden files.

Yet the computer reports only 1.35GB of free space and 4.65GB of used space on the drive.

Scandisk & Defrag have been run and found no errors, also up to date virus scans have also been run, finding no viruses.

By my math that means 2.30GB of space has vanished.

What could cause this to happen......????
