Generally speaking:

Erasing your disk: For most reasons to erase, including when reformatting a disk

Instructions for 'erasing entire disk' would include all partitions on the drive.

Select the main name of the SSD or HDD, when choosing what to erase.

The disk utility will reformat an erased drive, if you follow the directions.

If you only select to 'erase a volume' on the disk, that's only a portion of disk;

so that'd not be correct. ~ You want it all gone, so use tool for that job.

Take care & good luck!🌞🐝
