That explains why I had so much less disk space available after the hard
disk switch than before. On the old disk there were 31 files taking up the
space of one, now the files are separate, taking up 31x as much disk space
as before. I guess this is bad.
So, any idea how to undo this? I could probably rm -R /stand on the machine
and then tar /stand on another and untar it again on the first one.
However, is there probably another way? I guess I could leave one file in
/stand around and hard link the others to it manually. If this works, is it
of any importance which file I keep around? Or can I simply delete
everything but one random file in /stand and then re-link the others to the
one remaining file? Of course, a suggestion about better method would also
be nice ;-)

Nils
