Hopefully, this is an easy question for somebody. I am getting a 120 gb ssd. Normally, when I look in my computer to see my drives, the full size of a hard drive is not available as there is some overhead apparently. For instance, my 500gb drive says it's only 465gb. Is this loss of 35gb due to Windows overhead such as page file, recycle bin and system restore etc.? I'd hate to lose such valuable space on a ssd. I did read a bit of the windows 7 ssd optimization guide somewhere and am hoping these optimizations will restore some of this overhead I see.
