My Book Essential - Won't boot, disk "doesn't contain an EFI partition"?

Hey Joe,

Thanks for the reply, but what I’m looking for is a way for me to simply access the drive from my macbook pro now. The WD My Book isn’t accessible from either my PC or my mac, and I’m just looking for a way to make the files accessible on my mac again just so I have access to the files.

Is there a fix for the error that it’s giving me?
