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.
The only solution I could find was to install Tuxera. This suggestion was posted on a similar Q as the solution & it worked for me. Microsoft NTFS for Mac by Tuxera 2019
Well, you don't have to. Most probably last time you disconnected your drive unsafely and now system check it for errors, thus preventing it from instant mount.
Could not mount disk
(com.apple.diskmanagement.disenter error -119930868) What do I do?
There is no process "fsck_ext" running on my machine
Solution for my disk not mounting is to format it? lol
This worked perfectly.
First, thank you for the response. Ok, did that and now I get the message:
I checked the external drive and now I cannot save to it. Any suggestions instead of backing up and reformatting?
How are/were the drives formatted? If they were NTFS then the upgrade removed the software required for that format and will have to be reinstalled.
Top right hand corner...... in Disk Utility.
I see Media Type: Generic. I don't see "Format"
I had the same issue and I had to shutdown the machine, power on again and the issue was fixed.
I dont want to pay another app. Thanks!
My drive is also Seagate! Probably it's a Seagate thing? I tried to leave it over night- it didn't mount ( other drives I have are WDs and they mount ok.
The only solution I could find after much research was to download Tuxera. Now I can access my external drive quickly like before.
An external disk refuses to mount, com.apple.DiskManagement.disenter error -119930868.
