External Seagate 18 TB One Touch Hard Drive. I originally bought a different model off Amazon and experienced issues with it, so I sent it back to Seagate. They copied my data and returned this model. I'm not sure if it was brand new before they copied my data, or if it was refurbished. I'm only selling this hard drive because I decided to upgrade to a NAS so that I could access data wirelessly. I don't believe this model comes with the "Restore +" that you get with new drives since I'm reselling it.
