Cables for Iomega External Hard Drive

Lost cables!

Which cables do I need in order to connect my Iomega Ego Rphd-c external hard drive to my MacBook Pro from ~2010? The external has a Firewire, small USB, and a hole that says DC 5V under it. When I search online I see all these differences....Firewire 400 and 800 4pin and 6pin and I really have no idea about any of this.

Appreciate the help!
