NTFS external drives won't mount after security update 2021-003 (com.apple.DiskManagement.disenter error 49221.)

The best solution is to temporarily transfer the data from the NTFS volume to another location…

That could be difficult to do if the drive won't mount.

I have had the same issue. I can read my NTFS drives but cannot write to them using Paragon and tried EaseUS as well. Apple needs to repair this issue. It is not the NTFS software causing the issue.

I have got a same problem. I am using Paragon NTFS for my external NTFS drives. Before the 17th March Catalina update, everything was OK. Now, I cannot mount any external NTFS drive with the error com.apple.DiskManagement.disenter error 49221

. It is very important issue, cause I need to work with my data and no, I really do not want to re-format file system to exFAT, it is about 6TB of data.

I had to transfer files on another computer to spare media. Several times I tried to reformat with various applications, but alas, Catalina does not know how to mount an NTFS disk and it remains invisible.

I got the same d... problem in here too... would like to know what i could do to resolve this situation...

I can see the external 3tera hd in both NTFS for Mac and Disk Utility but no clue to mount this on my desktop...

Well, the only thing I have to add is that, unfortunatly the reason I've been using this type of software is because it permitted me to transfer files on both Mac and Pc. I don't know what will hapen when I reformat the drive again.

After reading this I realised your correct, so I emailed Paragon about this and they told me they are waiting for a fix from Apple so I emailed them back saying its most likely a problem with Paragon software and to fix it soon and I said people on Apple Discussion thinks the same. And they send me a reply mentioning this "as the Development team usually know better than people on the forum".

What great customer service, Now I'm truly worried wether we will ever get a fix from Paragon !

Bellow is the email reply.

Some of us live in the real world where not everyone is enlightened and have to juggle Windows / Linux and Mac computers and data. Given the history of Paragon and how key they are in providing services to allow Macs to interact with the majority of computers outside of Cupertino this 'native only' attitude should have gone down with the Titanic and it is really disappointing to see in 2022.

This is an update on my previous post.

Using the terminal to mount the disk, didn't last enough. After I shut down my laptop and I turned it back on the disk didn't mount. Also, the only time it mounted it was only "read".

How did you make work r/w/e?

I agree with you HWTech!

Third party compagnies have to be pro-active with Apple's updates but some just don't or are too slow to react quickly to those changes... maybe there a gap in communications between them and Apple... who knows!

In the early years, Apple reacted to user's need with the integration of tools that we'd to use in this «Windoze» world... remember Adobe Type Manager, MacLink etc... There are needs to integrate NFS, NTFS in the OS 'cause sometimes we should work and move HDD between Mac and PC... All this crap because PC's can't handle our format...

THe bottomline of all this is it shows how poorly Apple has become at testing their software. Every release is followed up with another release to fix the issues created by the last release.

There is no way that I am going to uninstall Catalina and then reinstall an earlier version. The risks associated with that are worse than the current issue. Apple is well aware if the problem but has a don't give a crap attitude about fixing ASAP. rather they say that the "fix" will be implemented in the next update, when ever that might be.

This level of poor code performance and poor support for a 3T company is really unacceptable. We shouldn't have to look for more software to buy to fix a problem they created causing our current NTFS software to fail. Suggesting a long terminal session that you have to do for every drive everytime you power up the MAC is frankly embarrassing.

"THe bottomline of all this is it shows how poorly Apple has become at testing their software. "

Nope. Apple is under no obligation to ensure its updates continue to work with third party add-ons. It’s just the opposite. Third party developers are obligated to make sure their products work with any changes Apple makes to its operating system, including security patches. If Apple had to wait for developers to get their acts together before making changes nothing would ever get updated. Furthermore it appears some of those third party developers are already coming out with fixes to their software. Closing security holes trumps keeping third party software working every time.

Bottom line, you are just plain wrong my friend.

Sorry I don't agree, Apple has a very poor record for quality. Every release is immediately followed with a string of fix releases. Apple software in more an more buggy. The prior CEO never let products out the door with such poor testing. You can argue about 3rd party support BUT there is really no reason for them to begin with in this case. APPLE is the one that decided to no longer support reading other filesystems. A tragic flaw on their part. This problem wouldn't even exist if they has simply kept their system an open platform able to read other file systems. With the annual march of apple touting updates that are more fluff than substance, I for one am about done with the apple universe. We all migrated to apple because it just worked. Now that is not the case. No reply required.

@Starbuck II

macOs still supports other filesystems and among them Microsoft's exFat. They rely on licence-free fs. One could surely argue that Apple could afford the licence-fee for NTFS. But: if it weren't for Windows' 4GB+-filesize and file-forks one wouldn't really need it. File-exchange with exFat works fine
