Should work. As I do the same thing within my own house with flash drives. My desktop is win7 / USB 2.0, my Laptop is win7 / USB 3.0. I’ve never needed to re-format my flash drives and I do get the speed increase from the USB 3.0 Laptop. I can imagine, with the proper operating systems involved: Portable HDDs should’t be any different.

you certainly can use both USB 3.0 and USB 2.0; the only difference is transfer speed.Yes, it comes with a (short) cable. Well, the computer end of the cable is the same for USB 2.0 and 3.0

You can store 500GB data in your Pocket size driver.
