My new Seagate 1TB Expansion External Drive Does not put full enablements on screen when first plugged in. I think I have managed to Back-up complete Computer Hard Drive but when I ask it to show me my photographs it says it does not have correct programe to open it error 0x80010108 appears. Do I need to download any more software to help the operation of this unit. am I able to get full operating instructions as there are none supplied? As I am a little slow printed instructions would be a great help. Thankyou.
