External Hard Drive won't turn on
I have just bought a brand new iMac and a new Western Digital 1TB External Hard Drive to use Time Machine on. I have plugged it all in, done my first back up and it all went fine.
Then, I turned off my computer and all the plugs to go to bed as usual, now when I have come back to it in the morning the Western Digital Hard Drive won't turn on! It's all plugged in and fine, but no life at all.
Has anyone else had this? Can anyone explain or help?
Thanks
