What causes this particular error and what can I do to mount this drive or retrieve the data from it?
iMac Line (2012 and Later)
I ran into this issue with a Western Digital 2TB drive... I had seen some irreperable disk errors and was ironically, attempting to back the drive up so I could reformat it... so, I was panicking because I've got some important data on the drive and was starting to research data recovery tools. After messing around and doing some research, I discovered the system was trying to run a filesystem check on it and was getting hung up.
I opened a terminal window and entered the following commands
$ ps -ef | grep fsck
$ sudo kill [pid from above]
BAM! Disk mounted just like that.
At this point, I opened Disk Utility and ran First Aid... which ironically unmounted the drive and then got hung up again... DUH! So had to repeat the process. At this point, with the drive mounted, I backed up the drive and reformatted it.
Hope this helps.
Does the Mac recognize the drive in the System Information window (hold down the Option key and go to the menu and select System Information)?
You save my life! Tks!!!
Yes, nice shortcut By the way. It says there that the drive is Journaled HFS+
So in the future, if this doesn't connect, in theory I could use diskutil mount -t hfs /dev/disk2 ?
Cool, I'll have to try that.
I could not find the fsck process in the Activity Monitor. I purchased the Tuxera app. It works for me 100% of the time.
So... how long did it take until it mounted your disk?

What does MS NTFS has to do with unresponsive mac formatted external disks?
Thank you for your help
Thanks this worked. Looks like it has something to do with exFAT file system.
I have the same exact drive. Accidentally unplugged it and now it won't mount (but I can see it grayed out in Disk Utility). You simply plugged it into a Linux computer to get it to work again?
Pfoe ****! Thanks so much man!!
I am experiencing the same exact problem right now.
Or "fsck_hfs" on macOS Catalina
