[comp.sys.next] Problems with Wren VI...

rca@cs.brown.edu (Ronald C.F. Antony) (02/26/90)

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... :)
