SCSI error

I've trying to install OpenBSD 3.3 on a quadra 800. 
The installer constantly hangs about halfway through
the base system or installing the etc files, or
anything else that is roughly the same size.  Error is
can't find blk in cyl or a scsi read/write error.  I
have tried multiple hard drives and even muliple
computers--the same issue always happens.  Whats the
story?
