It lenghted the UW/U2W SCSI bus beyound the three feet... And thus creating a bunch of weirdness... For some reason both HD connectiors are related... BTW: Watch it when your using the SCSI 50 connectors, for some reason mine blowned... (and it disable the entire on-board chipset) I think I was using a lower grade Centronic cable and it sparked when I connected the external... Anyway this is another story...
