Hi there, hubby has asked for an external hard drive that plugs in a usb port for crimbo. Apparently he wants to save all our photos on it so that if the main computer breaks down, we don't lose all our piccies - nice idea but I don't know anything about external hard drives. Can anyone please point me in the right direction and advise what type of memory I might need and where I can buy such a thing? Prices too please!!!
