Why doesn't Disk Utility remove all volumes?

I wiped out an external SSD in Disk Utility and created a APFS GUID Partition. Why is there an extra unmounted volume called APFS Physical Store disk2s2?


I thought wiping out the container removes all the volumes? IS the volume supposed to be there?

Did you follow this help article: Erase and reformat a storage device in Disk Utility on Mac - Apple Support.


Specific with step number 3 & 4 in the help article, where you need to select the device (in your case "WD My Passport 0820 Media" then proceed with Erase).


Hope it helps.

Follow the advise of @Sharhari and that should solve the issue.


Cautionary note - in supplied picture there appear to be a Volume called " CCC " - could that be short for Carbon Copy Cloners. If this drive was used with this Cloning Software - whatever is on there now will be Lost once the drive is properly reformatted.
