Using the work-around I mentioned earlier (delete the ZeoServer1 folder, 
pack > 1 day, after pack undo ZeoServer1 deletion) seems to have resolved 
the issue.  I tried packing the Data.fs again and the ZeoServer1 folder did 
not disappear this time!

The only thing I can think of this that there must have been some entry in 
the original Data.fs file that was causing the problem, and the pack removed 
that problem entry, but everything 'appears' to be ok now.

Thanks again for all the help!
