Would that be any different than just setting
them afterwards?

Anyway, I tried the mount as:

mount -t ext3 -o owner,group /dev/sdb7 /disk2

I see the same behavior as before:  I can view
items within /disk2, but not the contents of /disk2.

And of course the contents of any directory on
the primary drive.
