at least, if you are really sure, you made the right connections, test &
check it again. the sdi cables are very picky, if you "made" a connection,
be sure to fasten the screws also. sometimes it doesn't work without fasten

the ra81 & ra82 have in diagnostic port on the disks. you can get more
information about the disks, if you put a terminal at it. But don't ask, i
never done it, (i got my disks to run without it) try DejaNews.


hope it helps a little,
