Yes and no. From the SCSI FAQ: "[ANSI] specified that if an LVD device is designed properly, it can switch to S.E. [single-ended, i.e. "normal", SCSI] mode and operate with S.E. devices on the same bus segment." - http://h000625f788f5.ne.client2.attbi.com/scsi_faq/scsifaq.html#Generic099 So if you mix it with S.E., you lose its LVDness, e.g. you have to stick to a S.E. bus length; but you shouldn't fry any hardware. HVD (high-voltage differential, i.e. the original differential variant of SCSI) is another story completely! That is indeed flat-out incompatible with S.E. (and presumably with LVD too...) -- | | /\ |-_|/ > Eric Siegerman, Toronto, Ont.
