Well I had an old usb stick so thought to give the ReadyBoost a chance, put it in and set all the setting etc and restarted the computer, It didn’t make my system faster but made my Itunes works with out any crash, don’t ask me how. I don’t even know how that’s linked may be itunes is having trouble accessing prefetched data from the hard drive. Well it works so gone buy another super fast usb disk and use it

here is the video about ReadyBoost
