I have a vertex 30gb with win7, some basic apps and a few programs. I had 7gb free and then a few days ago I noticed i only had 1gb left free. Where did this space go? I'm not sure, I uninstalled office 07 because it wasnt working for some odd ball error and still I have almost no space left! All big programs and files are on my slave drive.
I deleted cookies, updated firmware, deleted files i didnt need, checked to make sure files were on the slave and not in my documents. What else is there to do? I cant find what is taking my space up!
thumb may be right, you may have to re-install the OS, and since your drive is so small, perform the tweaks from this article: The SSD Review.
I, on the other hand didn't do them, but I have 80GB of space, and am only using 22GB: Win7 Home, Office 2007, Quicken, and Norton are the major programs I have.
I did move my pagefile (a.k.a. winswapfile or virtual memory) to a HDD, but I have 6GB of RAM, so I never use it. This could be a real hog on your SSD! WIndows can allocate twice your memory size to the pagefile. If you need to know how to "move" this, just ask.
And move your "My Documents" and other Libraries to the slave drive, too. You can just drag and drop them from your "User" folder on the OS drive.
