RAID System Not Mounting - Error (com.apple.DiskManagement.disenter error 49244)

So I recently purchased a brand new MacBook Pro (M3 Max) because my previous MacBook died on me due to old age. I went to access my external hard drives which work fine, but my RAID system doesn't want to mount for some reason. It's greyed out, but unmountable nor does Disk Utility First Aid work on it either. Here's the thing- it was working fine last night, but when I did a system update overnight it suddenly stopped working properly (I'm currently running Sonoma 14.2.1) and is now no longer mountable. I have NTFS Paragon installed, but I'm not sure if that's the issue as I've not had a problem with it before but it did have me change some security features so it could access my external hard drives.


I thought that perhaps my disk was corrupted in my RAID system, so I unplugged it and loaded it up on a friend's PC to see if I could access the files through a different OS. Sure enough, worked perfectly. All the data is intact and ready to be accessed. So why can't my Mac access the RAID system? I have a TON of data on there that I need access too, so wiping it and starting fresh isn't really an option right now. Plus, the data isn't the issue anyways as it's easily accessed through a Windows OS.


I'm not a super tech savvy person, but any help would be most appreciated. This is a brand new computer (literally just got it yesterday) and it's frustrating that I can't access the files that I need.

Thank you for the reply and suggestions. I actually did end up finding a work around/solution and I'll post it below for anyone else who might be having similar issues. To your points though-


1) The cables are in good shape, so it wasn't them.


2) I tried a few different ports, no issues there (there better not be since this is a brand new computer lol).


3) I actually ended up rebooting my computer multiple times during the trouble shooting process and even went so far as to boot it in safe mode, reinstall the Sonoma OS, and do a complete factory reset which wasn't a big deal since it's practically out of the box brand new. None of these things seemed to make any difference in the long run though.


4) I did consider that the third party software might be an issue. However, when I factory reset my computer it completely removed the NTFS Paragon software and the problem remained, so it wasn't Paragon.


After doing a ton of research and reading through many blogs and community forums, it's pretty clear that this is a software issue with the Sonoma OS. I also came to this conclusion because my MacBook was able to mount and read the data on my RAID system yesterday but it wasn't until the system update last night that my Mac suddenly couldn't access the drive. Literally the only thing that changed from yesterday to today was the system update so that makes it pretty easy to deduce where the problem originated from. It seems a lot of people have been complaining about external hard drives and RAID systems not mounting ever since the Sonoma update, and a common fix (bandaid) for many seems to be to reinstall the Ventura OS which works fine and can read and mount the disks without issue. Before going that route, I decided to try a few more things first. Here's what finally worked for me;


I knew that the disk wasn't corrupted because I had plugged my RAID system into my buddy's Windows OS and it worked perfectly as intended, the data was all there and easily accessible. While scouring the internet for possible fixes someone, on some random Apple thread, had mentioned that they repaired the disk in Windows and then mounted it again on the Mac OS. I decided to give it a try, and it worked! I plugged the RAID system into my buddy's PC again and "repaired" or "fixed" the disk in question (there was nothing wrong with it), and then plugged it back into my Mac which read and mounted it almost immediately.


I have no idea why that worked, or if the solution is only temporary or permanent, but after literally a full day of trouble shooting and worrying that I was going to have to wipe the drive and lose access to literally terabytes of data I'm gonna take the win and breath a huge sigh of relief. Hopefully, Apple will be able to fix whatever is going on with the Sonoma OS in future updates.


I hope this information is helpful to someone in a similar predicament. Thank you @SravanKrA for your helpful suggestions and for your prompt reply!

Here are the steps you can try, working from the most common solutions to more advanced ones:


Basic Checks and Restarts:


  1. Ensure that all cables are securely connected to both the RAID system and your MacBook. Disconnect and reconnect them firmly.
  2. If possible, try using different USB ports or Thunderbolt ports on your MacBook, as well as different cables, to rule out hardware issues.
  3. Power off both the RAID system and your MacBook, wait for a few minutes, and then power them back on. This can often resolve temporary glitches.
  4. Temporarily disable NTFS Paragon or other third-party drivers that might interfere with disk mounting. You can do this in System Preferences > Security & Privacy > Privacy > Full Disk Access.
