thanks for the specs well it being a laptop you would not be able to connect the old drive up they are designed for only one i believe

you could always sell it on and recover some £££ for the new one you bought. the tutorial you followed did not help you much. if you have deleted data from it there is a possibility that you could install a linux operating system for notebooks but that would mean keep swapping drives (not a good idea). the advice i gave previous is for tower/desktop machines sorry.
