So I recently invested in a Mushkin Chronos 120GB SSD. I'm pretty happy with it so far despite the realisation that my Marvell controller is dogshit.
Anyway, I'm here for a different reason. When checking the used space on my SSD, the properties windows shows 82.1GB space used but when all files and folders (including those hidden) are selected it shows a total of 69.6GB.
Thanks for your response mcnumpty, I have disabled system restore (I have all my documents etc on a separate drive anyway). and it's freed up a lot of space. However, strangley, I'm gettint the opposite issue now...
