While a problem that is causing an issue with a volume can be caused by a problem at any of the levels, starting at the volume level ensures the least risk. And repairing a Physical drive can affect all partitions, containers, and volumes housed on the drive. Repairing a Container can affect all volumes within the container.

My reasoning for this order is to limit potential data loss when repairing. You can actually repair the devices in any order, but IвЂ™ve been using the following order successfully for a while: Volume, Container (if applicable), Physical drive. If this is an HFS-formatted drive, there wonвЂ™t be any containers under the drive level, just volumes.Д®ach item can be selected and repaired using the First Aid tool. At the next level under the physical drive is the Container (APFS file system), followed by the volumes. The organization of the devices is hierarchical, with the physical drive listed first, using the manufacturerвЂ™s name, or the model name or number, or both. The sidebar will now display all devices, including the physical drive and any APFS containers it may have, as well as any APFS or HFS volumes associated with the physical drive. (The View button in Disk UtilityвЂ™s toolbar will expand the sidebar to show all devices.)Д¬lick the View button in the Disk Utility toolbar and select Show All Devices from the popup menu, or select Show All Devices from the View menu. Since you may need to use the First Aid tool on volumes as well as partitions, catalogs, and physical devices, itвЂ™s a good idea to change the sidebar settings to display all devices. Launch Disk Utility, located at /Applications/Utilities.Дisk UtilityвЂ™s default settings use a sidebar that only displays storage volumes.

That is free and Apple tools will test if the drive is functioning as part of the erase operation.Disk First Aid, currently part of Disk Utility, has long been the go-to utility for verifying and repairing a MacвЂ™s storage system.
