Disk utility restore function failed
I recently purchased a new hard drive for my mid-2012 Macbook Pro and after installing it, I attempted to copy my old HD data to the new one with the restore function in disk utility and went through the steps correctly and said it had finished. Then I checked the new HD, which had none of the old data on it and checked the old HD and all the data was erased. Anyone have an idea on what happened?
