I recently went to my uncle's place and he handed me a seagate drive and told me it's an external one. So I looked up on the Internet and found out it is a Seagate GoFlex Desk external hdd from 2010 (I guess). Also I didn't receive any cables with it but I found out it uses a USB mini 2.0 for data transfer with the pc. Also I haven't been able to find out how much voltage power supply it uses.
