Hello Moritz,

thank you for the tip.
I mount with the following line in fstab:
/dev/sda3            /media/daten         vfat      
users,gid=users,umask=0002,utf8=true,quiet 0 0
So I have read and write permission to the directory (I am member of the
group 'users').

But it is indeed a problem of permission, but I don't know what's the
problem:
If I start GRASS in text-mode within OpenSuse, I can create a new mapset
(e.g. mapset1) within the location 'loc1' which I have created within
Windows and mounted as described. GRASS saves a new folder 'mapset1' in
the folder 'loc1'. Within the folder 'mapset1' there are two files: var
and wind and a folder named dbf.
After that a error message appears:

Sorry, no access to <<mapset1>>.

Mapsets in location <loc1>
----------------------
   PERMANENT              test.grc              mapset1

note: you do not have access to any of these mapsets

Then GRASS closes down. But GRASS has just created the mapset1 folder,
so I should have write permission, or not?
