Anyone using TestDisk?
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!

Again, thanks! The literature and prompts in TestDisk are misleading. It specifies HFS partitions as a type and a Mac type. In any case it’s the only one that will fit my budget right now.
If it was the question of just getting a drive, the Goodwill has compatible drives for anywhere from $5 to $25. Instead it’s a question of the configuration and files I do not have a backup for. Yes, the big problem is having a backup. Despite the technical difficulties, that should have happened. I could then just reformat, restore and go on my way.
The drive is the original that came with the system. 10 years isn’t bad for lifetime use.
I’m trying to determine hardware failure versus software. It’s in an external enclosure but I want to place it in another mac to eliminate the enclosure as causing hardware errors. In the meantime I’ve put another drive in the enclosure to see if any errors appear.
The easiest thing to do is to erase it and test it again. It would just take a few bad sectors to jumble everything so it couldn’t be read. DiskUtil has no problem with the drive but errors out on the volume.
I thinks it best to determine if it’s a hardware failure before purchasing a recovery software.
