I have two hard drives mounted under /data

One is /data/Files and the other is /data/Backup

I want to use a group ourgroup to allow five users user1, user2, etc. to all have read-write access.

I made a group and added the users.

I did: sudo chown -R :ourgroup /data
I did: sudo chmod g+s /data

I could not create subfolders in /data/Files

So I did: sudo chmod g+w /data

Still can't make folders. It says permission is denied.

via CLI:
mkdir: cannot create directory ‘/data/Files/NewFolder’: Permission denied

via KDE GUI:

Could not make folder /data/Files/NewFolder.

Any guesses what I'm not understanding or what I'm missing?

I did see something about ACLs, but I would prefer to try it this way first.

~$ ls -ld /data returns drwxrwsr-x 4 root ourgroup

Is the problem that these are mounted drives? Do the drives not inherit like regular folders would? It I set the same settings on /data/Files then would everything below it work how I’m expecting?

If that’s why, why does it behave like this?
