Hello there. I'm an idiot, pleased to meet you. I had 2 external drives connected to my Macbook Pro, both had time machine back ups on...I meant to delete one of these but deleted the wrong one, and dragged it into Trash. On realising my mistake I tried to drag it back out of Trash, as you would normally but after "preparing to copy" for four hours it told me the drive was full... It's a 500gb drive, and the Time Machine back up is the only thing on it, so presumably it's just trying to copy itself when the back up is still present on the drive, albeit in the Trash. How do I get my back up folder out of the Trash? Help!
