However, some users find that when they insert an NTFS or exFAT drive into a Mac, this error also appears. That's because they format the drive on Windows but for cross-platform use. Not all Windows allocation unit sizes (block sizes) are supported by macOS.

You can try to update your macOS to fix this issue or reformat the drive on Mac. Recover data from the unmountable drive with iBoysoft Data Recovery for Mac before formatting to avoid permanent data loss.

Uninstall Paragon/Tuxera NTFS for Mac application

Fix the com.apple.DiskManagement.disenter error 0 (or other codes)

If the hard drive still cannot be mounted on your Mac after trying the above priority measures, it shows that the com.apple.DiskManagement.disenter error 0 is caused by more complex issues.

Commonly, the corrupted format of the hard drive is the primary culprit. Under this circumstance, you can recover data from the drive with iBoysoft Data Recovery for Mac to avoid data loss and then reformat the disk.

Also, you can follow the ways listed below to troubleshoot the com.apple.DiskManagement.disenter error with different codes.

Check the connections

External hard drive mounting is an automatic communication process between the OS and the file system of the drive via the USB port. If there's a bug in the plugging process, something wrong with the cable, or the USB port not working, the external hard drive will fail to be connected or mounted.

You can try to eject and unplug the external hard drive and then replug it to another USB port on the Mac. Or replug the hard drive with a new matchable cable. If the external hard drive still doesn't mount automatically, mount it through the Mount feature in Disk Utility again.

Run the First Aid feature in Disk Utility

First Aid is a disk-checking tool on Mac. It can detect and repair errors related to the formatting and directory structure of a disk.  If there's a file system error caused by incorrect ejecting at the last time, a sudden power off, formatting, or other reasons, First Aid may solve it, and then the drive may be mounted.

After running First Aid, if the hard drive still cannot be mounted automatically, manually mount it via the Mount feature once again.

Using Terminal to mount the disk

As a command-line interface on Mac, Terminal allows you to control your operating system and make some changes. When there's a logical error in the process of mounting, the hard drive refuses to be mounted. But the Terminal can work as a bridge to let you take control of the core of the system and then mount the hard drive via command lines.

Force quit fsck_ext from the Activity Monitor

If you have used fsck to check the unmountable hard drive, this error may happen when the fsck is stuck in the checking process. Using Activity Monitor (the Mac Task Manager) can quit a process, even if it's in a loop or not responding. Thus, you can try to force quit the fsck in Activity Monitor.

Reformat the hard drive

If the mentioned ways still can't work on fixing the com.apple.DiskManagement.disenter error 0, it shows that the file system of the drive is probably severely corrupted. You have no choice but to reformat it.
