Using My Passport as a file storage device?

I purchased the “My Passport” device in order to clear off my PC hard drive of files that I don’t often need to access, but don’t want to erase.

I am concerned because the device “autoupdates” my PC.  Does this mean that the device will always match my hard drive?  What happens when I delete a file on my hard drive?  Does it still exist on the My Passport for retreival or do the updates delete that file as well?

Thanks!!

I don’t know what’s autoupdating. It’s never a good idea to trust important data to just one drive no matter who makes internal or external. Externals are cheap buy a second one so you can have 2 copies.
