Two APFS physical store disks appear on macOS Sequoia

You do not have 2 physical disks (only 1 is shown in your screenshot).

There is 1 physical disk ("APPLE---------Media") containing 1 APFS Container ("Container disk1").

In the Container there are 3 Volumes.

• Macintosh HD & Macintosh HD - Data are the standard Volumes on a Mac. The "Macintosh HD snapshot" in one of the Volumes is normal and is actually the macOS SSV that your Mac boots from

• The Volume whose name you blanked out is one you must have added yourself but with no further information there is no way to tell you what it is, what it's potential pupose may be, or what to do with it.

Please provide more information.

Your first screenshot did not illustrate two physical drives although you claimed you had them. And just so you know the redactions were unnecessary, they don't cover any personal information and seeing the full picture & names would have helped in my original reply.

Regarding the "Creedence ...." volumes, they are macOS cryptex disk images that are normally hidden and not seen in the Finder or Disk Utility. They are part of the operating system and cannot be removed.

To date there hasn't been a definitive explanation as to why they sometimes become visible. Thought among some of the leaders in these communities is that the presence of legacy software, anti-malware apps, cleaner apps & the like somehow triggers the visibility during an update or upgrade.

I have 2 APFS Physical Store disks…pic enclosed

The encrypted disc name is redacted on previous pic. I enclosed the pic to view the "architecture" of the volume group.
