I do a defrag with Diskeeper of my C drive and everything goes okay. At the end it tells me it is defraged. When you look at the drive map, two thirds of it is still in red. It is a 40 gig drive and I should have somewhere around 27 gig free. Explorer shows it has only 2 gig free. This all started when I put Norton Antivirus 2004 on my machine. I'm not sure but I think it may have something to do with the Norton protected files in the recycle bin. Norton protected files in the recycle bin is greyed out and not available right now.
