Silverlining 6.5.8 is indeed a useful utility (tautologically speaking), with which I format even drives for use under OS X (up to 10.4.11) if I intend to be able to boot into OS 9.2.2. However, that version of Silverlining will complain if you use it in a 9.1 or lesser environment, for which Silverlining 6.5.1 is much more suitable.
