Seagate Expansion 2TB USB External Hard Drive. I have sold other one and I have this one left. This is also external power so it has an adapter. Correct me if I am wrong but Anything above 1000GB cannot be powered by the older USB 2.0 unless you have the new USB 3.0 you can power a 2TB external hard drive. Asking 15K. Location ISB, LHR and surrounding areas. Call or sms me at 0322-437-4332.
