Is it possible to unformat external hard drive on Mac? Here, we will introduce how to recover data from formatted external hard drive on Mac.

First things first — stop making any further operation on the formatted external hard drive

After formatting external hard drive, the real data will not be deleted from the drive, but only been marked as deleted. That's why we can recover data after format. But it should noted that those data are easy to be overwritten by new data.
