I had just learned from a friend of mine on how to add ram without taking the computer apart, the method using Windows ReadyBoost I have an WD My Passport 500 GB External Hard Drive. I was wonder if it was possible to make this into a ReadyBoost Device. I have done this 2 times before with 2 Kingston DataTraveler G3 USB Flash Drives which equaled 16 gigs but was wondering if this was possible with an external hard drive. Any Help is greatly appreciated. Thanks in advance from coast123
