That's a silly question.

Already tried that.  Didn't work.   In fact:

   p at satan$ diff -r project2/ /dvd/
   diff: project2/Home and Small Office Networking/data/movies/chap05:
         Stale NFS file handle
   (snip)
   diff: project2/Intermediate Flash MX 2004/CD 2/Xtras: Stale NFS file handle
   diff: project2/Learning Access 2003/PC Exercise: Stale NFS file handle
   diff: project2/Learning Access 2003/readme.txt: Stale NFS file handle

   p at satan$ head -1 project2/Learning\ Access\ 2003/readme.txt 
   Lynda.com.Learning.Microsoft.Access.2003-CFE            

Any file that diff reported "Stale NFS file handle", I can cat, edit, play,
etc.  All the files are accessible from satan when I do something to them.

However, when I diff -r them, I get these Stale NFS file handle errors.

Lucifer is a very fast machine.  Satan is a relatively slow machine.  The
data is going over a LAN anyhow.   Could it be some kind of synchronization
between when data is sent by the foreign machine and when it's processed by
diff?

I don't even know how to diagnose the cause.
