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.

tout fonctionne depuis la mise à jour de tuxera,

since the update of Tuxera it’s OK for me

Oct 25, 2019 3:19 AM in response to yeison208

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

Oct 25, 2019 7:13 AM in response to luisr1031

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.

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 When I upgraded to the new macOS Catalina, Tuxera Disk Manager was outdated and needed to be manually updated (it doesn’t happen automatically like most other apps).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

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

re-partition whole disk with «diskutil eraseDisk JHFS+ UntitledUFS diskN» (diskN is your disk number my case it was disk2)

Disk Management disenter error 49244

Источник

I have a fairly new LaCie d2 4TB hard drive (roughly one year old). Some days ago it wouldn’t show up anymore and now I looked into the issue.

In disk utility the disk is unmounted. When hitting «mount» I get this error:

(com.apple.DiskManagement.disenter-error 49244.)

When trying to repair the disk I get the exit code 8 and

Invalid node structure (8, 0) Invalid B-tree node size (8, 0)

I also have Bootcamp installed and Windows can see the drive; it seems normal to me there. But it is formatted as Mac OS Extended so Windows can’t do anything with it. Do you have any idea what I can do other than reformat?

I read the in a different post that you can try the repair process in the terminal or boot into windows and eject the drive properly (yet, Windows isn’t even mounting a Mac OS Extended journaled drive, so how should I unmount it. Also a normal shutdown should do this job, too, and I have done that multiple times in both macOS and Windows). I have tried the terminal commands from the mentioned post, the only interesting part is, when using the sudo fsck_hfs -r -d /dev/disk5s2 command I get this error, where it also shows error 7.

** /dev/rdisk5s2

(The files are backed up, so it would be ok to reformat, but I would prefer being able to repair it)

What Types of Mac Errors Exist?

Just like with Windows devices, there are some general error types with Mac as well, including:

Runtime Errors – when you execute a program and it fails due to badly written code, incompatibility with the program and web servers or other problems, like malware.
Logic Errors – something in the logic makes the program fail to return results.
Arithmetic Errors – a type of logic error, which involves miscalculation due to an erroneous configuration or code that does not fit the same logic as the system reads it.

ИСПРАВЛЕНИЕ 1. Завершение процесса fsck

Одна из наиболее распространенных причин этой ошибки может быть связана с тем, что «fsck» может держать ее в заложниках. Поэтому вам придется убить этот процесс и повторить попытку монтирования диска. Вот как это можно сделать:

Для начала запустите Терминал и Дисковую утилиту.
Затем попробуйте смонтировать диск и сразу переключитесь на Терминал.
Теперь выполните следующую команду в окне терминала: sudo pkill -f fsck
Диск смонтируется в режиме только для чтения. Теперь вы можете восстановить его с помощью программы «Первая помощь» в Дисковой утилите.
Ремонт займет время. После этого это должно исправить ошибку Diskmanagement.disenter.

ИСПРАВЛЕНИЕ 2: использование терминала

Для начала загрузите Mac в режим восстановления, как указано ниже: Apple Silicon: нажмите и удерживайте кнопку питания, пока не появится «Загрузка параметров запуска». Затем выберите Функции > Продолжить. Intel: перезагрузите Mac и одновременно нажмите и удерживайте сочетание клавиш Command+R.
Затем нажмите «Утилиты» и выберите «Терминал». Теперь введите следующую команду: diskutil list
Появится список всех дисков. Запишите идентификатор тома вашего диска [such as disk3s1].
Наконец, выполните приведенную ниже команду [replace diskX with your volume identifier].diskutil repairVolume/diskX
Проверьте, исправляет ли он ошибку Diskmanagement.disenter 119930868, 119930872, 49218, 49223, 0.

ИСПРАВЛЕНИЕ 3. Изменение размера выделяемого диска

Некоторые старые Mac не смогут смонтировать диск, если размер выделения больше 1024. Поэтому, чтобы решить эту проблему, перейдите на компьютер с Windows или Linux (или используйте виртуальную машину) и переформатируйте диск в ExFAT и выберите 1024 как размер выделения. Теперь попробуйте установить его на свой Mac, и на этот раз вы не получите никаких кодов ошибок.

Вот и все. Это были три метода, которые должны помочь вам исправить ошибку Diskmanagement.disenter с кодами ошибок 119930868, 119930872, 49218, 49223, 0 и т. д. Если у вас есть какие-либо вопросы относительно вышеупомянутых шагов, сообщите нам об этом в комментариях. Мы вернемся к вам с решением в ближайшее время.

Такая ошибка может возникать при стирании данных и разбиении на разделы. Это происходит, потому что ОС пытается использовать том «Зарезервировано Microsoft» емкостью 134,2 МБ для тома EFI, минимальный размер которого — 200 МБ. Технические подробности см. в документации Apple.

Эту проблему можно решить разными способами, но проще всего отформатировать накопитель с использованием схемы разделов GUID. Тогда Дисковая утилита сможет создать на нем собственные тома. Если этот вариант недоступен, включите режим просмотра Показывать все устройства вверху слева (см. начало этой статьи).

Если накопитель будет использоваться и с macOS, и с Windows, сделайте резервную копию всех важных данных с него и отформатируйте его в exFAT под macOS. Как отформатировать накопитель в exFAT…

Если вы планируете использовать накопитель только в macOS, отформатируйте его в Mac OS Extended (журналируемая). Этот формат оптимизирован специально для устройств Apple. По-другому он называется HFS+. Как отформатировать накопитель в HFS+…

Такая ошибка может возникать по ряду причин. Это происходит, если накопитель занят — например, когда на нем открыт образ диска. В таком случае извлеките образ и еще раз попробуйте отформатировать диск.

Если вы считаете, что диск не занят никаким процессом, просто запустите форматирование еще раз. Если это не поможет, выделите том и нажмите «Отключить». После этого мешающий процесс должен завершиться.

Если и это не поможет, выключите компьютер, отключите накопитель и перезагрузите компьютер. Когда ОС загрузится, подключите накопитель и вновь попробуйте его отформатировать.

Ошибка: ошибка com.apple.DiskManagement.disenter 49223

Такая ошибка случается с накопителями, отформатированными в exFAT. Если накопитель используется и с macOS, и с ОС Windows, его нужно форматировать только на компьютере с macOS. Дело в том, что она не поддерживает некоторые размеры кластеров (блоков), создаваемые при форматировании в ОС Windows. Из-за этого накопитель может не подключаться. Это сообщение об ошибке выводится, если попытаться вручную подключить накопитель в Дисковой утилите.

Ошибка: ошибка com.apple.DiskManagement.disenter 49153

Такая ошибка характерна для внешних жестких дисков и некоторых других накопителей. Она возникает, если диск отформатирован в NTFS и для него используется драйвер Paragon. Обычно причина проблемы заключается именно в драйвере.

Чтобы решить проблему, удалите и заново установите драйвер Paragon. Как удалить драйвер Paragon… Если у вас macOS 10.13 (High Sierra) или более поздней версии, при установке обязательно выберите для расширения ядра опцию «Разрешить». Если кнопка «Разрешить» отсутствует, попробуйте смонтировать накопитель с помощью программного обеспечения Paragon и проверить, не выдается ли сообщение об ошибке. После этого кнопка «Разрешить» может появиться на панели «Защита и безопасность».

ПРИМЕЧАНИЕ. Версия Paragon для дисков Seagate несовместима с накопителями LaCie. Если вы используете полную версию Paragon, удалите и вновь установите ее, следуя инструкциям в Paragon.

Что делать, если решить проблему не удалось?

Если у вас есть доступ к другому компьютеру Mac, попробуйте подключить накопитель к нему и вновь запустить стирание данных.

Если у вас есть возможность воспользоваться другим компьютером с ОС Windows, подключите накопитель к этому компьютеру и отформатируйте его с помощью утилиты diskpart. Как пользоваться diskpart… Затем вновь подключите накопитель к компьютеру Mac и попробуйте стереть данные.

What to Do If You’d Lost Data After DiskManagement Disenter Error?
Conclusion

When you plug in your external hard drive, the system mounts it and makes its contents viewable in Finder. If it doesn’t show up there, you should still see it in Disk Utility (Finder > Applications > Utilities) where you can also attempt to mount it.

But there are cases when your external hard drive won’t mount, even using Disk Utility. In this scenario, you’ll probably encounter an error that says “Could not mount *name of the drive*”(com.apple.DiskManagement.disenter error 49513).

Several factors could lead to this problem. You may have an incompatible file system. Or, you may be using a Mac Superdrive while running macOS Catalina. Beyond those common reasons, error 49153 may occur simply due to malware, bugs, issues while resizing partitions and interference from local Time Machine backups.

Don’t worry – we’ll show you how to get rid of this pesky error in the next section.

How to Fix com.apple.diskmanagement.disenter error 49153?

There are several ways to address this specific error code, but most fixes can potentially harm your data. We suggest opening your external hard drive in read only mode and copying your files to a separate storage device or to the cloud.

To set your drive to read only mode, right-click your drive > Get Info and scroll down to Sharing and Permissions. Set your user’s privilege to Read only.

Method #1: Connect Your Drive to Another Mac

Disk Utility errors can be caused by either your drive or your Mac. To figure out which methods to try first, connect your drive to another Mac or even a PC. If your drive doesn’t work on other machines, then the problem likely lies with your drive.

If it works on another Mac, then your Mac might be experiencing glitches due to a faulty update or other issue. If it works on a PC, then it’s likely a formatting problem – we wrote more about that in the section of this article that covers other common DiskManagement Disenter errors.

Method #2: Restart your Mac

A temporary bug or glitch may have simply gotten macOS stuck while it attempted to recognize your drive. You may also have a lot of apps running in the background using up the resources macOS needs to properly recognize and mount your drive.

To get your system going, a simple restart might solve the problem. This will automatically close all running apps and reboot the operating system.

Method #3: Use First Aid in Disk Utility

First Aid is a useful tool that finds and repairs disk errors – specifically, it scans the drive and its partitions for issues related to its structure and formatting. These may prevent your drive from properly mounting.

Fortunately, First Aid is a feature of the Disk Utility app, which can recognize unmountable drives or partitions. To repair your drive using First Aid:

Step 1.Launch Disk Utility (Finder > Applications > Utilities).

Step 2.Select your drive from the left sidebar, then click the First Aid button at the top of the window.

Step 3.In the dialogue box that appears, click Run.

Step 4.Wait for the process to finish. Then, manually mount your hard drive in Disk Utility by selecting your drive or volume in the left sidebar and clicking the Mount button.

Method #4: Use the fsck Command in Single User Mode

Your external hard drive may not be mounting because of a file system issue. To resolve this problem, you can use Mac’s File System Check command or FSCK through Single User Mode. Here’s how:

Step 1.Enter Single User Mode. To do so, restart your Mac. As soon as it starts to reboot, press and hold the Power button and the CMD + S keys at the same time.

Step 2.You’ll know that you’ve successfully booted into Single User Mode when you see a window that looks like the Terminal app. Once the white text stops appearing, type the following command and hit Return.

/sbin/fsck -fy

Step 3.Once the process is complete, type reboot. This will command your Mac to restart itself.

If you remove your hard drive before ejecting it from Mac, fsck will automatically scan and repair it the next time you use it. This could potentially take a long time, which makes your drive unmountable. To deal with this, force quit the fsck command (Open the Activity Monitor > search fsck > click the x button).

Method #5: Disable Time Machine

Time Machine is a Mac built-in tool that regularly backs up your data, usually automatically. It works well, but on bad days, it can cause the operating system to get stuck while preparing your backup drive. Try disabling Time Machine to free your drive from this process and hopefully allow it to get mounted.

To disable Time Machine, open its settings window by launching System Preferences > Time Machine.

Then, untick the box beside the Back Up Automatically setting.

Method #6: Delete Time Machine snapshots using Terminal

Deleting Time Machine snapshots from your Mac may also resolve this disk utility error. Learn how to do it using the Terminal app by following the steps below:

Step 1.Launch Terminal (Finder > Applications > Utilities > Terminal).

Step 2.The first command we’ll execute will list all locally stored Time Machine snapshots. Type the following command and hit Return:

Tmutil listlocalsnapshots /

Step 3.Type the following command and hit Return:

Tmutil thinlocalsnapshots /99999999999999

Step 4.Keep using the tmutil listlocalsnaphots and tmutil thinlocalsnapshots commands to make sure you delete all your snapshots.

Method #7: Format Your Drive

If all the above methods failed to get rid of the disk errors, your last resort is to format the drive. As we’ve already discussed earlier, formatting your drive will wipe the disk – including errors, viruses, corruption, and unfortunately, your data. We suggest copying your files to a secure location first.

To transfer your files safely, set your drive to read only mode first. To do this, read our pro tip in the introduction of this section.

Fortunately, formatting your drive on Mac is very easy thanks to the Disk Utility app. First, launch Disk Utility (Finder > Applications) and select your drive from the left sidebar. Then, click the Erase button on the top of the window.

In the dialogue box that appears, name your drive and select a format. If you will only be using your drive with Mac computers, choose APFS. Otherwise, we suggest exFAT for maximum compatibility. Select GUID Partition Map for its scheme, then click Erase to proceed with the format.

Other Types of DiskManagement Disenter Error

Aside from DiskManagement Disenter Error 49153, there are other DiskManagement Disenter errors that you may encounter that are represented by different codes. Below, we’ve listed the most common ones along with their solutions:

DiskManagement Disenter Error 49223. An exFAT hard drive that’s been formatted using Windows can cause this error when connected to a Mac, as macOS doesn’t support all the storage block sizes available on Windows. This incompatibility makes MacOS unable to recognize and mount the drive.If you want to use this drive on both Mac and Windows, you need to format it using Mac (but first, back up your data!). If you intend to use it solely on Mac, we suggest formatting it to Apple-based APFS.
DiskManagement Disenter Error 49221.This error is caused by a glitch in the security updates 2021-003 and 2022-003. After the update, you’ve probably tried to mount a NTFS hard drive in Disk Utility when you got this error. To fix this, reinstall macOS or use a third-party software to mount your NTFS drive.
DiskManagement Disenter Error 49244. This error often appears when you try to mount your hard drive in Disk Utility while running macOS Catalina. You can use third-party software to mount your drive. If that doesn’t work, you need to format your drive to APFS (again, don’t forget to create a backup!).
DiskManagement Disenter Error 49218. You might get this error when you remove a hard drive without proper ejection while using macOS Monterey. This error may also be caused by bugs from macOS Monterey itself.To fix it, (1) execute the sudo pkill -f command in the Terminal app, (2) execute the fsck /dev/disk_user_id/ command in single user mode, and finally (3) execute the mount -f /dev/disk_user_id/ command. Remember to replace “disk_user_id” with your disk’s identifier (diskutil list). To boot into single user mode, follow the first instruction in Method #4. If your drive still fails to work after this fix, you may need to format it.
DiskManagement Disenter Error 49180. This error occurs when there’s a raw partition on the drive, which can happen if you connect an APFS drive to an old Mac or if something went wrong while you were shrinking your partition. You have two ways to address this error: (1) resize the external hard drive using Terminal or (2) format the hard drive altogether.

What to Do If You’d Lost Data After DiskManagement Disenter Error?

Disk Utility errors always have the potential to cause data loss and there’s no guarantee that your files will remain intact after fixing them. The safest and most efficient way to restore data caused by disk errors is to use data recovery software.

Data recovery software can restore files regardless of format – it will even work if you decided to format your drive due to the errors. For this article, we’ll be using a tool called Disk Drill. It’s easy to use and works with most disk formats, and it can restore data even from non-mounting drives. Here’s how to use it:

Disk Drill Basic for Mac does not offer free recovery. However, you can back up and preview your files for free. There are free data recovery solutions available on the internet, but they each have their own limitations – your mileage may vary.

Step 1.Download and install Disk Drill for Mac.

Step 2.Launch Disk Drill (Finder > Applications > Disk Drill).

Step 3.Select your drive from the middle pane and click Search for lost data.

Step 4.Wait for the scan to finish, then click Review found items.

Step 5.Use the search bar to filter the results by name or by file extension, or use the left sidebar. You can also hover your mouse pointer beside any file to enable preview.

Step 6.Use the boxes in the left-most column to select the files you want to restore, then click Recover.

Step 7.Select a location on your non-malfunctioning drive to save the recovered files. Then, click OK.

Conclusion

Bluntly, disk utility errors are inevitable. Buggy system updates, improper ejection, power surges, and other factors beyond the user’s control can cause one or multiple disk errors. Not only can these errors cause data loss by themselves, but the process of actually fixing them can also harm your files. The best you can do is to routinely back up your files to avoid the worst consequences of these errors.

Help! one of my most important hard drives refuses to mount! (no, I wasn’t smart enough to make a back-up)

I try to mount it in disk utility and I keep getting this message :

Could not mount “5V”. (com.apple.DiskManagement.disenter error 49244.)

can anyone help? I have tried using a different USB connecting device, and also tried mounting in different computers.

as you can see, the drive appears in Disk Util, but it is grayed out, and that is the error message I get when I try to mount it.

failing all else, can anyone recommend a good hard drive recovery service in Manhattan?

thanks!

if it is important I would suggest getting a proper data recovery specialist to look at it for you, as screwing around with random ideas from the internet (which is what you will get here) if you don’t know what you’re doing is likely to do more harm than good.

live and learn, take backups next time.

thanks. have you ever worked with a data recovery specialist? Can you recommend one?

Not sure if any of this will help, but might be worth a read.

I’m not sure where this question should be posted. I’ve got a 3 tb Western Digital My Book Studio external drive that I use for backups. I bought it in July. I’ve got a 2 tb partition that I use for Time Machine and a 1 tb partition that holds old photos/music files. Last night, I started…

If the drive is formatted in HFS+, a product like DiskWarrior can more then likely correct the issue. DiskWarrior has been a staple for me for years. It works great on HFS+ formatted drives. It is not free though.

ALSOFT — Makers of DiskWarrior.

DiskWarrior is a utility program designed from the ground up with a totally different approach to preventing and resolving directory damage.

update: yes, I tried DISKWARRIOR — and yes, it seems to have worked! so far, so good. Totally worth the $130 it cost.

thanks for all suggestions!

HELP! Could not mount (com.apple.DiskManagement.dis enter error 49244.)

Hey there,

Been having a problem on trying to open my Seagate Expansion 8TB HDD to my Macbook M1 Pro Max, doesn’t pop up on finder and when I try to manually mount it on Disk Utility it shows Could not mount «PPSC». (com.apple.DiskManagement.dis enter error 49244.).

What I’ve found online didn’t help me, does anyone have any clue how can I solve this problem?

PS. The disk is formated exFAT and it works fine on a Windows computer.
