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.
I’ve since allowed the disk check to run its course (took about 30 mins for 1TB disk) now works without issues.
This worked for me also, I found I had to do this every time I used the drive.
I left the fsck to run its course (about 30 minutes for 1TB) and the disk works correctly every time now.
Thanks. This works. Good job. How did you find it out?
Did this and the disc is back! Thank you!!
I checked the list of services but I did not find the "fsk" process in the disk window of the , even when performing a search.
Name changed ?
It does resolve the issue with the right extension e.g. fsck_hfs. Double click on process listed in Activity Monitor and choose quit.
Thanks for this, you saved my ***.
this worked for me
Same issue, saw this post about Tuxera, and it was the only thing that worked. And it worked straight away! Thank you.
That worked for me. Opened Activity monitor and force quit fsck_ext. Thank you so much!!
Thank you @ph290! This worked like a charm :-)
I remove my external drive (ExFAT) without properly ejecting it and faced similar issue. Could not mount it in OSX. I had to scan and fix it from a windows machine then it got fixed.
Hey all,
I found a fix for this.
update dyld shared cache -force
reboot in safe mode
reboot again normally
It worked of 4 computers for me so far
Let me know if it works for you
I am not agreeing with wrongly ejected position. This clearly a kext file disrupting the usb mount. If you boot in safe boots it will mount. The big question is why and which I extension is it.
I need to access my to my external hard drive.
An external disk refuses to mount, com.apple.DiskManagement.disenter error -119930868.
