   I'm trying to hook up a second hard drive to my IIcx and I can't get the finder
   to recognize it.

   Here's what I did.  I bought a used Qunatun 40 meg HD and an external case and
   power supply to hold it.  Now, I know it works, because I can substitute it for
   my internal HD and get it to boot up and all.  So what I did to hook them both 
   up, was to hook the drives up in serial fashion using a SCSI cable that has
   connectors every couple of inches.  I took the original SCSI cable out, hooked
   one end of the new cable to the original connector, one of the middle connectors
   to my internal drive, and finally the other end to the new drive.  Now, when I
   boot up, the internal works fine, but I can't get the mac to recognize the
   external.

It sounds to me like both drives are trying to use the same SCSI ID
number...
