Disk Recovery

Over the years I've had the need for various data recovery solutions. I have found that Disk Drill and DMDE are great when a drive is unmountable. Both will give you a preview of what's recoverable before allowing you to copy the files to a new drive. They are paid apps and require a license purchase for certain features.
From about error 49218:
Try to mount the disk, and switch to Terminal and write sudo pkill -f fsck
Attempt to run First-Aid on that partition. Restarted the computer. Also try First Aid in recovery mode.
