I am using Win7 with a ssHD of 80 gb. A year ago I reformatted the HD.At that point I had 30GB of free space.After supposedly blowing away everything,I still had only 40GB of free space. I suspect that when using the WIN 7 disk to reformat--I loaded the operating system for a second time. When my SSHD was brand new,I recall that the OS only took up about 8GB!!! Is there some way to actually blow everything back to 0 GB--and reinstall OS from scratch!!!! As of now I only have 6GB of free space. The only thing installed on my computer is WIN7 and LOTR on-line(which accounts for 30 + GB!) Initially I had ,when new Win7 8Gb LOTR 30GB Total WarII 30GB installed --which with other miscellaneous stuff gave me 10gb free after I blew away Total War ,I had about 35GB free and after I reformatted ,I had 10GB free So now,If I want to try to format,I am informed ``not enough free space`` And that is my sad Story!!!
