Disk Management disenter error 49244

UPDATED YOUR TUXERA DISK MANAGER

I had the same error today. When I upgraded to the new macOS Catalina, Tuxera Disk Manager was outdated and needed to be manually updated (it doesn't happen automatically like most other apps). Once I updated Tuxera, I was able to mount all my external hard drives.

Tuxera didn't work for me. I used Diskwarrior instead and that worked. I've used Diskwarrior in the past to solve a different problem using a Drobo 4 bay array with 10TB drives. Until I used Diskwarrior, nothing worked on both the one 1TB drive I just fixed (that had the same error message when upgrading to Catalina) and the Drobo array that wouldn't work with Mojave. I saved a ton of data with the fix to Drobo as you can imagine.

I recommend trying Diskwarrior and maybe using it in your utility arsenal.

I got same issue while i was copying boot image suddenly remove usb from mac. thereafter mac doesn't recognise my usb even i format usb using windows machine. so I clearly read error message so then I realised partition table has issue. to fix that I used below resolution

1. plug usb and open terminal with diskutil list ( in my case it was dev/disk2
2. re-partition whole disk with "diskutil eraseDisk JHFS+ UntitledUFS diskN" (diskN is your disk number my case it was disk2)

mac Os Catalina and mac book pro 2018 version

Thanks

You need special software to be able got access and use an NTFS volume. A system upgrade will remove that software so you'll need to reinstall it.

tout fonctionne depuis la mise à jour de tuxera,

since the update of Tuxera it’s OK for me

I Updated Tuxera and it worked

I have restored some suddenly "invisible" hard drives using DiskWarrior as well. It also helps clean up the file system to run it every now and then.

For me it helps to just wait an hour while leaving the drive connected.

After a while it mounts by itself again.

I do see it greyed out in Disk Utility, but it is not mounted at first. Only after waiting and letting it spin for a bit.

Tuxera Works perfectly so far. Had bought the previous version in 2015. Bought a new license key just now.

Same issue is happening on my MacBook Air Mid-2015. But it is not mounting anything, not even update nor any other download image (DMG file). External disks nor Time Machine either.

Does any one got any answer for that? Tuxera didn't worked as well.

Workaround I am using is downloading in other machine, extract file do disk and copy using AirDrop, but is it not a solution.

Thanks.

Après la mise à jour de mon imac vers macOS Catalina, mon disque dur externe ne s'affiche pas. Le lecteur est reconnu sur l'utilitaire de disque, mais lorsque j'essaie de le monter, le message suivant "Impossible de monter" Backup". (Erreur 49244 de com.apple.DiskManagement.disenter). Comment puis-je résoudre ce problème?

My Macbook pro also got this problem when I insert my WD Mobile Hard disk.

There are so many important files

And what will happen when your free trial expires?

Hi,

In utilities, the hard drive was greyed out. I can't mount my new hard drive. I just keep getting the error.

I'll take it back to the store and see what they can do.
