Okie dokie - in that case, you could probably expand your script to 
re-download the files via ftp once they had been uploaded. Then do the 
checks against the original (download them as a different filename or to a 
temp directory)

Basically, you have file integrity issues, the only real way to solve 
these if to verify the integrity of the files when you upload/download 
them.

Out of curiosity, where did you try to gunzip/gzip -t the files ? and if 
they were on a windows box, how did you get them back to the unix box ?
