It's been over 24 hours with it running and there has been no change. I aborted the defragging and re-ran analyze fragmentation rate is the same. When I was watching the drive map yesterday none of the squares turned green, or yellow. Also in spite of the roughly 25% free space only 1 of the blocks is white. I notice that I didn't specify that it's a NTFS drive like the others which is was able to defrag.
