Yes, put this in a file, put the file in, say, /usr/local/bin, and then
call it 
via root's crontab.  BTW, after looking at the script I suggested, it
occurs to 
me that this would be better:

#!/bin/bash
for file in /home/Drop/*
do
owner=$(ls -ld $file|awk '{print $3}')
chown -R $owner $file
done

The problem with my first draft is if there is a directory in which the
owner is 
not the same name as the directory itself.  For example:

drwx------    4 jwilliams user2        4096 Aug 21  2003 /home/user2/

Here jwilliams is the owner but the directory is named user2; my first
draft 
would fail on this one.  This may not be an issue for you, but the
revised 
version is more precise, so use that one.  I also changed the variable
name from 
x to file to make it easier to read.
