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.
Had the same issue yesterday, ended up downloading DiskWarrior to rebuild the directory file (It took like an hour for it to be rebuilt and had no data loss)
Have you ever tried https://www.tuxera.com/products/tuxera-ntfs-for-mac/
Hi, I am trying this command in Terminal and just wondering how i find out what the [pid from above] is?
Thank you! That worked.
For some reason Apple moderated out the offending process, which is mentioned all over this thread and I can't edit the post!!
The process I stopped is eff ess see kay. Hope it helps.
Your suggestion works. Thanks a lot!
Thank you! After few weeks of searching for a solution, finally this helped!
I searched in Activity Monitor and fsck_ext isn't running.
I get no such process with that command.
I can't find the file named fsck_ext , it doesn't show up anything by that
same here
How do you know what the format of the drive is? In Disk Utility is there a way to find out the format? Is there a Terminal command?
That's because you're not looking at Disk Utility.
Sorry, yes you are but you've gone to "info".... no need, it's on the very first window.
Control (right) - click on the drive's icon on the Desktop and select "Get Info" from the contextual menu. The Info window will show the format.
Yup, that showed me that it's a Mac OS Extended (Journaled) format.
An external disk refuses to mount, com.apple.DiskManagement.disenter error -119930868.
