tout fonctionne depuis la mise à jour de tuxera,
since the update of Tuxera it’s OK for me
Oct 22, 2019 12:13 AM
Tuxera Works perfectly so far. Had bought the previous version in 2015. Bought a new license key just now.
Oct 25, 2019 3:19 AM
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.

I am having major issues with spinning external hard drives after installing Catalina. I’ve had 2 hard drives die and a 3rd is now failing to mount.

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.

(com.apple.DiskManagement.disenter error 0.) In my case.
Is there a way to make my WD Mybook work again also on Catalina MBPro 2019? Strangest thing is that i have same model Mybook at office and it works fine with Catalina on Imac (27 late 2013) Both hdd’s are xFat and was working perfect before catalina update.

Have similar error after updating macOS Catalonia. What should I do to rectify it. Have 4Tb of files in my external hard disk and it is not mounting.

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 When I upgraded to the new macOS Catalina, Tuxera Disk Manager was outdated and needed to be manually updated (it doesn’t happen automatically like most other apps).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.

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?

I have the exact same issue. except its with my Macbook’s internal SSD. yeah.
Happened sometime roughly after I upgraded my mac to MacOS Catalina. One day, I decide to restart my mac, and then next thing you know it can’t find it’s boot drive. Question mark icon on a blinking folder when I try to boot up.
I would really like to just be able to mount my internal SSD again so I can access my data normally, but for now I am stuck booting off of an external drive with MacOS Catalina installed, using 3rd party data recovery software to try and save some of my data before I will probably inevitably have to format the SSD and start over again.
Any known fixes to mount my internal APFS drive? Its not even recognized as a boot drive when in recovery mode. Thinking this is more serious than I’m making it out to be!

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
- plug usb and open terminal with diskutil list ( in my case it was dev/disk2
- 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

How did you reinstall this? Did you buy the Tuxera software?

I have an iMAC, and after updating to Catalina I have a similar problem. I have a two partition external HD. It mounts de Time Machine partition, but not the NTFS one. I use Tuxera NTFS to read and write on it. The question is that the iMAC does not mount the partition even for reading.

On ,the , Disc Utillity you can see your Harddrive?
I can not see why, this, issue is any,problem?
The Toshiba EXT is your Harddrive Backup.
«Count not Mount»? Purchase a new Time machine Back-up?
Run a new Back—up ,if this is the problem?
Oct 18, 2019 5:44 PM
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.

I also have this problem after upgrade from Mojavie to Catalina. MacBook pro 13 2017
Oct 19, 2019 4:42 AM
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.

Ok so its been a week since i pressed the «i have this problem too button»
i spent most of my days not being able to write on the disk only read it and last night i tried to repair the disk again in disk utility. it didnt seem to do anything but this morning i noticed it finished the process and i pressed mount and it worked.
Sharing & permissions changed to » you have custom access». what i want to say is ease us and tuxera didnt do anything or the western digital discovery. The only thing that worked was my patience.

Open Activity monitor and forse quit there fsck_ext. Will solve issuer.
Oct 29, 2019 7:03 PM
This doesn’t really help. I don’t want to lose all the info I have on my external drive. You’ve made it sound like it’s the drive issue but it’s really with how the new Catalina update is working to read these drives. Please provide a better fix. I need drive access without reformatting & it’s worked fine up till the latest update.
Oct 19, 2019 6:53 AM
On my system, I just have to wait for some time till I can mount my external drive (SD, for example).
Seems like Catalina runs fsck on them if they were not safely removed last time.
Drive mounts itself after it’s checked for errors. It just takes time.
Oct 23, 2019 11:36 AM
I’m having a similar issue — «com.apple.DiskManagement.disenter error 0.» since the Catalina upgrade.
I’ve a partitioned 2Tb drive — half I drag & drop files to, the other half is for Time Machine. I have another disc that I use as a backup for the files/data but not as Time Machine.
My partition for dragging files into mounts but the Time Machine partition won’t. It wt was last seen in action trying to backup a few days ago but announced it had insufficient space.
I’ll also post on a Time Machine forum

I recently purchased a new IMac and upgraded it to Catalina. BIG mistake!! I have this same problem and it will not mount any external hard drives. These drives all still work fine on my old macBook running Mojave 10.14.1. This problem started when I Accidentally unplugged a drive and didn’t trash the icon first. Another problem is Disk Utility and some other programs will not respond to a QUIT command. The only way to get them to quit is to force quit them. I assume you will have a fix soon.

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

Have the same issue with my external drive on my MacBook Pro
com.apple.DiskManagement.disenter error -119930868
The drive cannot be mounted in OS Catalina (10.15.1), drive is APFS 3TB HDD. Disk Utility shows it greyed out and if I try to mount it I get that error.
I tried to plug this drive in my friend’s iMac with Mojave 10.14.6- it works just fine! Does anyone know how to make it work with Catalina?
Nov 12, 2019 9:29 AM
This is really interesting..I did a bit of investigating myself. Seems like while Catalina starts, codes like «fsck -fy» would be running in the background to determine if a drive is mounting or not. I wonder if something is missing in those codes that disallowing some external disks be read (My HD is Seagate — 3TB — NTFS) or there is a link between Catalina’s security code that sends a signal to your antivirus software saying that, the drive is a virus and should not be mounted. I suspects that because I formatted my Mac and it was under OS X Lion, whenever I plugged my HD in, a window of my antivirus popped up and said «blocked autorun.inf because it was infected with INF: Autorun-BH(Wm)» and I am back to Catalina with the same computer, there is no message when I plug in my HD. Yet, my drive is grey out from the list. All of my other WD drives are ok in Catalina.

My Lacie 2TB portable hard drive suddenly couldn’t be mounted on my Macbook Pro (Running Catalina) after it shut down because of low battery power. When I restarted. nothing. I tried to mount it on my MacPro, (High Sierra), same thing and I freaked.
After reading here that all I had to do to restore it, is wait, I didn’t think it could be that easy. but it was. It took about an hour, leaving the drive connected before the computer could mount the drive. All is good.
Nov 15, 2019 8:39 AM
Now I wonder what affected that @dhbaker. I mean, one second it is working and after the update, it has to take an hour to recover the drive. I have a few 3TB drives and they are all mounted quickly (all WDs). I found out that Lacie is owned by Seagate and so they use Seagate’s drive. The drive I could not mount is a Seagate! coincident?
Nov 15, 2019 9:33 AM
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.
Nov 15, 2019 9:51 AM
@roman127 right. even though I called the apple support and they claimed it is something to do with my drive. They said they could send me to Seagate support. I didnt think it was anything to do with Seagate but I tried going through Seagate’s website. It looks like they have a data recovery app called pixel8 and it could read my drive, just wouldnt mount but it discovers the files I have in the drive. It will cost $99US for a year of subscription to recover my HD. I wonder why they came up with this software pixel8. I also found out that Seagate does not have a lot of support on Mac side. On PC side they have firmwares and softwares. So I am not sure what the problem between Seagate and Apple is, not supporting each other. For customers, we are in the middle and cant get our problems solved.
Nov 15, 2019 10:07 AM
So I think I will also contact Apple Support regarding this issue. But I have really strong argument here- my Seagate drive mounts and works ok with Mojave, so they won’t be able to tell me that this is the problem with my drive.
Nov 15, 2019 10:23 AM
Excellent. Great idea @roman127. I need to reverse back to Mojave and see if it would work. It is a pain because I just got back to Catalina from X Lion. I think I will try a time machine method to backup this computer.
Nov 15, 2019 5:01 PM
The only solution I could find after much research was to download Tuxera. Now I can access my external drive quickly like before.
Nov 16, 2019 5:51 AM
As unsettling as this is, it’s good to know it’s not just me having this issue.. hopefully at some point a fix can be found!
Nov 16, 2019 6:13 PM
Apple must fix this and soon or the future of OSX will be compromised.
Nov 16, 2019 9:04 PM
OK, first off I’m quite a junior when it comes to Mac’s. However I got this issue resolved. I did the the convert to APFS system as it seemed to be the «smart» thing to do. However the drive showed out grey. I couldn’t mount or erase or restore, just nothing. I believed that in the conversion the drive would be partitioned. It was not. After a call to Apple Care they determined they didn’t know what the problem was either. After the call I tried the partition option. Problem fixed in 10 seconds. I don’t know if that’s the issue but it worked for me. Good luck!
Nov 20, 2019 2:44 PM
That saved my bacon!! Thanks very much, worked like a charm
Nov 22, 2019 4:25 AM
Running OS Catalina on a new MacBook Pro. I just had a drive fail on me (WD 2TB) after mounting quickly for the past 24 hrs. Did not eject it manually — literally the drive unmounted itself while I was adding a Word document to it for backup. Other drives I own work fine (WD and Seagate), I could open the drive great on a windows PC, and a recovery app found the documents while loaded onto the problem Mac. The fsck command was not running in background, per activity monitor. So now I’m recovering my recovery drive on a second backup until this temper tantrum fixes itself.
I don’t think it’s just a Seagate thing, this definitely seems like a Catalina thing.
