Upgraded my computer, how to retrieve back-up

I knew I was going to upgrade my PC and backed up my old computer. I misplaced my CD that came with my passport Ultra and used the software setup that showed up after plugging my passport into the new computer. It made a partition into it, and all it shows on the passport drive is empty. Did this erase all my data? If not, how do I find the data that was stored onto it?

Try checking Show Hidden Files and see if that helps.
