my external HDD (used for TM backups and some other stuff) suddenly stopped working with my MBP 2017 (Sierra 10.12.6). I can see it only through the Terminal (see screenshot 1)
DiskUtility won't load when this particular HDD is plugged. I have also tried several diskutil command lines:
Did not perform the last one, cause I really don't want to lose my data. Tested on two Windows machines with Apple_HFS driver. Driver was found and data are just fine and readable.
Someone with an idea how to fix this without losing data? Any help will be appreciated!
