Warning: Sometimes, the verification can take a very long time with Mojave (sometimes more than an hour)!
Some antivirus software or processes that are running in the background may prevent verification.

The disk needs to be repaired but Disk Utility finds no problem
Sometimes, the disk needs to be repaired, but when attempting to repair it, the Disk Utility application finds no problem. It is a Disk Utility issue that does not visibly recognize all errors.
Then, you will need to repair the disk using the fsck command in single-user mode.
