Seagate Hard drive: how do I delete back ups?
Hi, I use a Seagate hard drive to back up using Time Machine. I can now only back up incrementally so need to delete old back ups. I've not been able to find a way of doing this. I did click and drag to the Trash, but now can't empty that. Can anyone offer advice on how to resolve these isues? Thanks, David
