Question: I’m trying to recover a single 4 TB ExFat partition made in Maverick’s Disk Utility.

This single partition on the disk has storage files shared between Windows and Mac.

It became inaccessible after a Windows performed a repair reboot on the main hard drive.

Here’s what TestDisk has found:

1) Disk selection

2) Quick scan finds MS DATA. Is the size correct for a 4 TB drive?

3) Deep scan finds another identically sized partition. Which one should I choose?

“Write” is the last option and I lack any other backup for this hard drive.

Doing it right the first time is a must.

Please advice.

Answer: I found all the necessary steps in the TestDisk guide.

With the P key I was able to see all the files, and proceeded to Write the partition table.

For future reference, select rDisk instead of Disk, it’s the raw format and reads the partition much faster.

A big thank you to the developers behind TestDisk, without it the solution would have been much harder!
