When I described the procedure to install Wren VI Diskdrives, I mentioned that 2 of the 3 cubes I tried that with work fine, where as the third has problems. The cause for the problems is found: NeXT's manufacturing robots most probably screwed up: on both the optical disk and the scsi connector on the main board was bent down one pin (relatively to the connectors at exactly the same position). Obviously they were some kind of drive ready signal or so. This way the harddrive was only recognized correctly if a opical disk was inserted. After bending back the pins everything worked fine (and still does). I have however still a bad feeling, since I no longer trust these pins. they have now been bent VERY far forth and back again... Changing/adding memory to the mainboard is a kind of a challenge now... I will talk with NeXT about that. At least the process of installing the drives was correct. Now if some scsi-guru would program a lowlevel formatter... :) Ronald ------------------------------------------------------------------------------ "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
