I have a 40 GB USB hard drive formatted with NTFS on a PC running Windows XP Pro, SP3. I am trying to free as much space as possible. Windows Explorer tells me that I have about 200 MB of files on the drive (showing hidden and system files). When I show drive properties however it shows 73% free, around 10 GB used.
I ran CHKDSK and it found all kinds of problems.
Now running defrag and it is behaving as if there were 10 GB of files, but I can't access them anywhere.
How to find and remove this extra 10GB?
