Run First Aid on everything and you should get an "Operation Successful," message for all. Once Disk Utility is open, turn on the drive. Once you get to your normal desktop, keep the drive off and open Disk Utility. Go to the Apple icon in the left uppermost corner and select restart. Now, unmount all volumes and then turn off the drive. You should get an "Operation Successful," return. Once again, run First Aid on the disk and each partition. Now that all volumes are approved by First Aid, you can partition the drive into whatever partitions you want. This should lead you to "Operation Successful," on both the disk and each volume. Run First Aid on the main one and then on the volume(s). Once Disk Utility appears on the screen, turn on the drive and make sure all volumes are mounted. Once you reach Recovery Mode, select Disk Utility. Go into Recovery Mode by restarting your computer and pressing command + R simultaneously. What you need to do is eject/unmount each volume and then turn off the external hard drive (you can leave the external hard drive plugged in, just turn it off.)

I'm posting the solution just in case anyone ever has the same problem and errors because the people at Apple Support will not help you since they don't know how to fix this issue and will just wash their hands off the problem by telling you to contacting Customer Support for your drive's manufacturer. What must I do for this external hard drive to start cooperating with me again?Īlright. I want to run First Aid successfully on all partitions and for Disk Utility to let me make the two partitions mentioned above, without having the dreadful "Uninitialized," partition reappear. What's most curious about this is that even though I get an error at the end, First Aid tells me that, " File system check exit code is 0." However, when I run First Aid on the "Untitled," partition, I get this error: An internal error has occurred. When I run First Aid on the disk as a whole, the operation is successful. I am left with one 3TB partition labeled "Untitled." Please verify and repair each volume individually and then try again.

This time, though, I can delete the Uninitialized partition, but the same error ( Couldn’t modify partition map because file system verification failed. When I try to make three partitions so that I can manually delete the "Untitled," partition by reducing its size (since I can't just (-) this partition once it is selected), the horrible Zero KB * Uninitialized partition reappears in its place. I finally have only one 3TB partition labeled "Untitled." My woes did not end here, however.Īs I tried to partition the drive into (1) a 2TB partition for Time Machine and (2) a 1TB partition for specific files backup, I get this error: Couldn’t modify partition map because file system verification failed.

I finally managed to get rid of the Zero KB * partition formatted as "Uninitialized," by formatting the entire drive to APFS and then back to Mac OS Extended (Journaled).
