My newish Sony Vaio (VGN-SZ5VWN) Computer tells me that I only have 2GB of 176GB free. Yet I have only used about 28GB of my hard drive. Programs like TreeSize Free confirm that I am only using 28Gb. So where has the other 150GB gone!

I have run Check Disk but still no joy.

I have all files and folders visible (via folder options)

I am unable to do a system restore (as I assume that I do not have enough disk space.

Help!

Any ideas?
