NO NO NO!  If there are only two drives in the chain, they are _both_ supposed
to be terminated.  Some people claim to have luck with SCSI chains which are
not 'properly' terminated, but you should really try to stick with the way
things are supposed to be if at all possible - I can almost guarantee it'll
save you headaches some day.  

Please check into things before you post.
