TestDisk a Nifty Utility for fixing drives with bad boot sectors

Just ran into an interesting problem with an external hard drive that was being used as a time machine backup for laptop. Someone tried to connect this drive to their windows machine and it evidently screwed up the boot bits so not only would windows not recognize it, Macs wouldn’t recognize the disk either.

Tried running it through Disk Utility but received a message saying “Disk cannot be repaired.”

So I loaded up TestDisk and took it for a spin. Here is a photo gallery outlining the steps that I took.
