why does my hard drives show 332 gigs used when there is only 67.3

[Guest]

i have recently reinstalled vista due to faults and issues and may have to do
it again. My hard drives are 500gig mirrored raid and when in c drive it
appears that 332 gigs have been used which appeared odd as its a new
reinstall i have higlighted the files in c: and found that there is only 67.3
gigs worth off files on the drive. I dont think this is normall but any
suggestions would be very handy thanks jonny.

Yes i did but as its a new install i wouldn't of thought that it would come
to that much. My music only takes 47gig

Check what the raid bios utility show for total disk space, maybe there is a
hidden partition.
