Time Machine wants to erase my new drive!

Scotty, trying to back up on my new back up plus portable. Stopped because it said ... are you sure you want to erase...
Help please


Yes it is fine to Erase it. You just bought the drive so there is nothing on it that is important to you. Time Machine wants to reformat it so it can use it the way it would like. Reformating a drive means the drive must be erased in the process. Since the drive is brand new and you just took it out of its packaging, there is nothing on the drive that belongs to you. Go ahead and select "erase". I try to always mention this step to people because it's very common to be concerned when seeing such a seemingly scary message.
