suddenly a POwerMac 7600 with G4 Sonnet Crescendo and a bige G3 desktop stopped recognizing external FW hard drives. I do not recall if I ever connected an external FW HD after upgrading to Mac OS 9.2.2 (it requires a specifc strategy as the installer does not allow to instal 9.2.2 on these machines.

By the way can it be that Os 9.2.2 chenged something?

A b & w G3 can read those HDs.
