Fix com.apple.DiskManagement.disenter error 49223 on a Mac with 3 Ways

I have a new Mac, but after a day of use, it no longer recognizes my external hard drives. It's not a disk problem because on the old Mac it works fine. I see it on the disk utility, but if I try to activate it, it gives me this error: (com.apple.DiskManagement.disenter error 49223). Even in safe mode, it gives me the usual error. Can you help me?

Suppose your Mac shows the 'com.apple.DiskManagement.disenter error 49223' error when recognizing an external hard drive; the reason why the error 49233 occurs most likely when you mount an external hard drive formatted with NTFS or exFAT on your Mac, where you can only read the external hard drive on a Mac.

In this case, you have to utilize a third-party software to access stored data on the NTFS/exFAT hard drive. EaseUS Data Recovery Wizard for Mac can quickly scan all data on the unmountable drive and recover it in one click.

⚠️Note: You can directly format the external hard drive if it doesn't store any essential data. Formatting it and choosing a macOS-compatible file system format for the erased hard drive can fix the error code 49233 effectively.

Fix 1. Re-mount the External Hard Drive Manually

Step 1. Launch 'Terminal' from the 'Applications > Utilities' folder.

Step 2. Type the command diskutil mount /dev/(disc identifier) in the Terminal window, and hit 'Enter'.

Fix 2. Repair the Hard Drive via First Aid

Step 1. Open 'Disk Utility' and choose the external hard drive from the external disk panel.

Step 2. Click on the 'First Aid > Run' button on the top menu.

Wait for the First Aid process to complete, and check if the error 49223 is fixed. Suppose the First Aid process fails; consider reformatting the hard drive to make it work correctly.

Fix 3. Re-format the Hard Drive

Step 1. Connect the exFAT or NTFS external hard drive to your Mac, and open 'Disk Utility'.

Step 2. Click 'Erase' at the top menu, and choose a new name and file format for the formatted hard drive.

Step 3. Click 'Erase' again to confirm the formatting.
