I am having a problem with my 3TB WD Internal HDD (Green).
I am running a hackintosh with my 3TB as a slave formatted in exFAT. My partitions have disappeared (I actually only have 1 main exFAT partition on it), but I was able to run TestDisk and it was able to correctly identify the partitions. In fact, it even lists the files correctly. However, when I select "write" and reboot, nothing happens; the disk still does not mount.
During quick search, I get this:
