An external disk refuses to mount, com.apple.DiskManagement.disenter error -119930868.

Your problem is related to a previously disk ejection not done properly. The disk does not mount because Disk Check is in progress, you should see fsck process in the Activity Monitor app. Unfortunately MacOS does not tell you about any progress so you try many times to plugin / out your disk.

Unfortunately my problem above is different (left the whole night and there is no disk check in background), but found software that should recover files. Its a shame that third party sw can fix this and Apple does not help in fixing APFS issue.

After trying many of these possible solutions to the following error:

Could not mount (com.apple.DiskManagement.disenter error 49153)

This https://forums.macrumors.com/threads/invalid-content-in-journal.1941721/ worked for me! I finally gained access to a 2 TB San Disk thumb drive with an HFS file system.

My 2012 Macbook Pro Retina with Mac OS Catalina was not running the FCSK process either, so that possible resolution was N/A for me.

I'm having the same issue. I am upgrading to MacOS Bigsur as soon as possible. It seems like it is only happening to users using Catalina. Someone even said that their iMac Pro running Catalina has this issue but not their MacBook running Mojave. I also didn't have this issue at all until I upgraded from High Sierra to Catalina. Either I wait a billion years for Bigsur to release, or I get support and downgrade to Mojave.

ABSOLOTELY.

Tuxera is the way to go.

If the issue is exactly as is being discussed out here - then this is the one stop solution.

Just a few minutes and it has resolved it - in a snap!

Thanks guys. Ever so grateful.

Had lost sleep over it last night .... !!!

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.

Or "fsck_hfs" on macOS Catalina

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

What helps me was reinstall Mac OS.

Hope, that will helps somebody else.

Open Activity monitor and forse quit there fsck_ext. Will solve issuer.

I had the same problem with a Seagate 6Tb drive - partitioning worked for me too. Cheers!

Worked for me, but it wasn't called fsck_ext, it was fsck_something else. Quit the process and the drive mounted.

Hi, what do the commands below mean or do?

$ ps -ef | grep fsck

$ sudo kill [pid from above]

im having trouble with my external hard drive as I won't mount. I was going to try this but don't have a clue what it would even do! im not too good with computers (sorry if this is a stupid question)

I have a 5T WD drive that's already been formatted for a Mac, therefore EX-NTFS. Did you have any issues after downloading Tuxera? I'm having the same problems everyone else is with mounting. I get com.apple.DiskManagement.disenter error 0

Thanks for your help.
