"Data" drive in Big Sur

When I upgraded from Catalina to Big Sur the other day, the "- Data" drive started showing on my desktop after I turned on "Hard Disks" in Finder preferences. (I like to be able to see the main drive.) The "Data" drive had not been displaying with Catalina.

So I've been dragging it to the trash when I launch. Is there a way to suppress that disk without me having to do that every time I launch?

Also, there's nothing in the "- Data" drive; it shows zero contents. Everything is on the main drive. is that correct?

Or did I incorrectly do an Erase and Install?

Thanks,

Nick

Not the same thing— you have two data drives showing in your screen shot.

if you have Two  Macintosh HD - Data


from Disk Utility.app you can see the mount point

One will be mounted at /System/Volumes/Data   this is the one you want to keep,


The other will be mounted at /Volumes and you can simply use the “ -“ to delete it.


here is an example of a properly formatted drive:
