Seagate External Hardrive
hi
i have just brought a seagate external 1tb hard rive to store all our photos. I have plugged it in but it won't allow me to transfer any documents or photos over to it.
There doesn't seem to be any instructions on how to install or if i need to.
I have googled and they say to format it it will erase all my documents on my hard drive. is this correct?
can anyone help me please?
thanks laura
