I’d like to discuss using TestDisk on a drive gone belly up in my MacBook Pro…

Its not designed to work on HFS+ or APFS volumes so it likely won’t help you Unless you are running a BootCamp and it will only fix the Windows partition/s To fix HDD’s I would use one of the major OS-X/macOS drive tools like Drive Genius or DiskWarrior But be warned! Neither will fix APFS volumes! Apple has not release the needed information for 3rd parties to repair corrupted volumes or disks which are encrypted either. And lastly, if you are using a SSD you don’t need either of these tools as unlike the mechanical drives SSD’s work at the block level directly! But you do want to review your SMART status using this tool DriveDx which can also be useful for HDD’s as well. You do want to make sure you are working with the correct drive for your system This series only offers a SATA II (3.0 Gb/s) interface. Using a drive which is only a SATA III (6.0 Gb/s) drive win’t work reliably! Review your given drives spec sheet if it does not list SATA II (3.0 Gb/s) don’t use it!
