How can you know 明明只係用左40GB ? What Windows O/S you use? What kind of computer you have?
If your computer is brand name computer, such as IBM, Dell... etc, the O/S will pre-load in your computer, when you want to recover the O/S, you don't need any disk being the O/S already in the harddisk and hidden at somewhere... and also, did you clear all temp and Recycle Bin? How many space you assign for Windows sleep mode? Did you set the System Restore Point? All of above also use many many of your hard disk space... Please check.
