The WD7000 controller is a multifunction controller. If you take a good look
at it, you'll see an external SCSI connector, an internal SCSI connector, a
floppy disk connector, a Winchester disk control connector, and two Winchester
disk data connectors. My internal 697MB disks are connected to the disk-control
and to the disk-data connectors. If they were SCSI disks, they would be connected
(ie. daisy chained) to the internal SCSI connector along with the internal ctape
units. I just opened up the DN3500 and checked the disks. They are Maxtor
XT-8760-E disks. It's my impression that these are ESDI drives. Running
/systest/size_scsi on my system returns the following:

Testing for 0:0  
    SCSI controller 0 present
          Attempting to aquire device #0, on controller 0
          Target 0:    Removable    Sequential (tape)     ARCHIVE VIPER 60 21116-007 VP60S-07

Note that this sees the ctape, but no disks, on the SCSI bus of the WD7000.
Check your disk's model number. If it's not a Maxtor XT-8760-E, I'd be
interested in knowing what model you have.
