Another way to fix com.apple.DiskManagement.disenter error 49153 on external drives is to log out of your Mac and then log back in. Simply go to the Apple menu and select Log out, then select your account to log in again.

Way 4: Restart your Mac

A reboot can resolve all sorts of minor issues on a Mac. If you haven't tried it already, try rebooting your Mac. Safely eject the unmountable drive and unplug it from your Mac. Then restart your Mac and reconnect the drive.

Way 5: Restart in Safe Mode

Safe Mode is a common troubleshooting mode that can help you rule out third-party software interference, clear system caches, and quickly check your internal hard drive for errors. You can boot into Safe Mode and then restart your Mac normally to see if that mounts your external drive or USB drive.

On an Intel-based Mac:

On an Apple Silicon (M1 & M2) Mac:

Once in Safe Mode, you should see the words "Safe Boot" in the menu bar. Go to Disk Utility to see if the drive is mounted. If not, click the Apple menu and select Restart to reboot your Mac.

Way 6: Quit the fsck process

If you have unplugged the drive before ejecting it from your Mac, the fsck process may be checking and repairing your drive, rendering it unmountable.

To verify whether the process is running, you can open Activity Monitor and search for it in the search bar. If it is working, you can either wait until it finishes its job (left the drive connected overnight) or quit the process by selecting it, clicking the x button, and selecting Quit.

Way 7: Turn off Time Machine automatic backup

If you receive com.apple.DiskManagement.disenter error 49153 when trying to mount a Time Machine disk, you can turn off Time Machine to fix the problem. Here's how to do it:

Way 8: Try it on another computer

If you can't mount an Apple SuperDrive or a generic external CD or DVD drive formatted with an old file system like HFS, try it on a computer with an older operating system. It seems that HFS is no longer supported since macOS Catalina. If you don't have another Mac available, you need to reformat it with a more advanced file system.

Way 9: Reformat the unmountable drive

If you still can't mount the drive on Mac, consider reformatting it in Disk Utility. This erases all content on it and gives it a working file system, which is often the most efficient solution to mounting issues on external drives. If you haven't restored data from the unmountable drive, use iBoysoft Data Recovery for Mac to get it back first.

Seeing that your data is secured, you can use the steps below to erase the drive:

Wait for the erase process to complete. After that, your drive should be automatically mounted in Disk Utility. If the erase process failed, read this guide to fix it: [Complete Guide] Disk Utility Won't Let You Erase Hard Drive
