(com.apple.DiskManagement.dis enter error 49153 Disk failed to mount on MacBook Pro running Ventura 13.4

Hello Frustratutorial,

If an external hard drive is not working with your computer, you can try running First Aid on it to correct the problem.

1. Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

• Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

• Intel processor: Turn on your Mac, then immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R.

2. You may be asked to select a user you know the password for. Select the user, then click Next and enter their administrator password.

3. From the utilities window in macOS Recovery, select Disk Utility and click Continue.

Once you're in the Disk Utility menu, select the drive name in the sidebar, then select the First Aid option at the top of the window. If First Aid is able to complete successfully without any errors, restart the computer then see if you're able to access the drive.

How to repair a Mac disk with Disk Utility

Cheers!

This is a user-to-user technical support forum. We do not have the power to change macOS, so we cannot do as you request.

Your best approach to have Apple change macOS is to contact Apple Support, or send Feedback - macOS - Apple

or obtain a free Apple developer account and file a bug report.

But telling the users in this forum to fix it is just going to add to your frustration, because nothing said here will affect macOS.

The disk is a WD My Passport Ultra 4TB drive. Got popup error message "NTFS for Mac

Failed to mount volume /Volumes/4TB for

I've put in bold the source of the problem. That appears to be some third party software you are using to manage the external drive on this Mac. Make sure that third party software (probably a part the WD software you installed) is completely up to date.

If the WD software is up to date, then I would suggest uninstalling the WD software by following WD's instructions, making sure to reboot the Mac afterwards. Then see whether you can read the data on that drive. FYI, you will not be able to write to the NTFS volume, but at least you can access the data on it. Otherwise you will need to contact WD technical support for assistance.

FYI, there is no need to install any third party software to manage an external drive. Most of the respected regular contributors on this forum recommend allowing macOS to manage external drives. You do this by making sure to use Disk Utility to erase the external drive so the external drive is using a file system which macOS supports. Which file system you choose depends on how you will use the drive.

For external data drives the options are:

• MacOS Extended (Journaled) --- needed if using the drive with older Macs running macOS 10.12 or earlier. Plus it is best to use it on hard drives.
• APFS --- newer file system only accessible on Macs running macOS 10.13+. Ok to use on SSDs, but should be avoided on hard drives because it may make the hard drive work much harder & cause extra wear. Necessary for Time Machine backups with macOS 12.x+
• exFAT --- best option if you want to share the drive with a Windows computer, just make sure to use Disk Utility on macOS to erase the drive. If you use Windows to erase the drive, then macOS may not be able to mount the drive since Windows may use a file allocation size which is incompatible with macOS.

Erasing a drive will destroy all data on the drive so make sure to have a good backup of the existing data before erasing a drive. Technically a simple erase of a hard drive will leave traces of data behind, but a simple erase on an SSD destroys all data.

I don't know why this disk decided to use NTFS all its life.

Many external drives come pre-formatted as NTFS from the factory since it is a Windows focused world.

So now, I can see WD Discovery and I can uninstall that. But frankly I'm scared to do it!!!

I can still read all the data on the 4TB hard drive using my older computer. But, will I be able to read it on my newer computer? Will I even be able to mount it if I uninstall WD Discovery (which incidentally makes no mention of NTFS)? Will I really be able to read the files if I uninstall WD Discovery, which, I assume, includes NTFS? Please correct me if I am wrong.

Make sure the WD drive is disconnected before uninstalling the WD software just to be safe. This will only affect this Mac. You already are unable to mount this drive on this Mac, so I don't see a problem with uninstall the WD software. I have no idea whether you will be able to read the drive on this Mac after uninstalling the software.

macOS has the ability to read an NTFS volume, but is unable to write to an NTFS volume without third party NTFS drivers.

I would like to have some reassurance. e.g. why am I able to mount and read and write with an older 2TB HDD on both computers?

There could be any number of reasons such as an issue with a cable, adapter, dock/hub, or the port on the Mac. Maybe another external device is interfering with it. Maybe the file system on the 4TB WD is damaged. Maybe there is a hardware issue or even a compatibility issue with the 4TB drive. Different computers and different operating systems may behave differently when something unexpected occurs with a drive.

Maybe you have some other third party software installed which is interfering with the normal operation of macOS. Usual culprits are anti-virus apps, cleaning/optimizer apps, and third party security software. If you have any of these types of apps installed, then uninstall them by following the developer's instructions since these types of apps are not needed on a Mac, plus these types of apps usually cause more problems than they solve. If you have any of these types of apps installed, then you should uninstall them first before uninstalling the WD software.

You can run EtreCheck and post the report here if you want us to see whether any other third party apps may be the cause of the problem with being able to mount this 4TB WD drive on this particular Mac. This report will also give us the summaries of some system logs which may also possibly provide some clues.

Uninstall both CleanMyMac and ESET by following the developers' instructions as neither app is needed on a Mac. These types of apps interfere with the normal operation of the OS with CMM being notorious on these forums just by itself.
