I have a 3 TB thunderbolt drive, formatted as exFat, which I was using for data storage. Yesterday I booted up my Mac and found that the drive wouldn't mount. Disk utility shows an unformatted drive. I tried it with a PC, connecting via USB, and had same result.
Does anyone have a recommended method for recovering the partition? In the past, I've used programs such as Puran to recover individual files, with limited success. I'm wondering if there's a better solution.
