I've got two drives in my pc, one 20 gb and one 80 gb. The smaller one I use ONLY to store stuff, I haven't got any installed software on it, and it's driveletter is H:, So how come, when I run diskkeeper to analyse my drive, there's a large block of system files and reserved system area? I don't even use anything on the drive, and the virtual memory is located on the larger drive.
