It will work with any hard drive, modded or retail. Ive not seen the transfer cable for the slim, however I believe it is exactly the same as the one given out by ms for a few years now. Failing that just connect your hard drive to a sata connection in your PC as show in my guide. Remember you need to run it with admin rights for it to work. If you had the games installed before you will need to delete them and re install otherwise they will be running off the disc and not the hard drive. If you have already done that them im not sure. Do the games freeze then not installed? As for using the hard drive in the PC its not something I have looked in to, you might be able to just format / partition it in disk management... however its not something I really want to try on my 20gig drive, ive just left it how it is in case I ever need a drive for another 360.
