Thanks for the quick replies, guys!Oh one thing I forgot to mention, the permissions may be a little wacky when trying to access the old drive on the new laptop. Google how to "take ownership" over a folder to fix these permissions.
Think I will be going with BlazinBlue88's suggestion. I don't get the chance to visit my uncle all that often so just being able to do it in one visit seems more convenient rather than taking it back home with me and him having to wait until I have the time to visit again.
