I have 4 harddrives in my system, 120gig SATA, 160gig SATA, 80gig SATA, and a 40gig IDE. The 120 is my C Drive and the 160 is for my games and backups. The other 2 are different OS's. I use Norton Ghost and make backups to the 160 drive. I made a new backup lastnight and it was about 48.5gig. So it was only showing that i have 13.4gig of free space on that drive so i deleted the old backup and it still shows there is 13.4gb free. I selected all foldes on the 160 drive and it adds up to 91.0gig so that means i should have about 57.0gig's free. So i cut the backup folder off of that harddrive and but it on another drive and the 160 still shows there is 13.4gig's free. I then tryed to put the backup folder back onto the 160 drive and it said i do not have enough room to move it there. I ran Check Disc and it still shows 13.4 free. I tryed to defrag the drive but it said i have to have 15% free to perform a defrag. I hope someone can help me with this because i do not feel like formating that drive. Thanks, cookiemonster[MoA]
