Even better is to purchase a Seagate Free Agent 1.5T and use Clone Pro 3.8 This will make a ghost copy, or mirror image of your internal HD.
Then if crashing occurs, you take out the old HD, install the new one and presto you have a copy of all files AND programs ready to re-install.
If you do this immediately after purchasing a new PC and loading up your programs and files then you have a “fresh copy” of everything.
You can plug it in and save any files by drag and drop anytime……
