Lots of ideas. What version of the HardFrame firmware are you using, for
starters?

Second the HardFrame is terminated on the controller. Have you removed those
terminators? They are immediately adjacent to the SCSI connector pins.

If you are using the (yuck) 25 pin header for the external drive are you running
25 wire cable to the drives and expecting it to work? I can virtually guarantee
that it will not with a HardFrame. That is a fast controller coupled with a
rather demanding drive, the Maxtor. Inproper bus termination and those idiot 25
wire cables *WILL* cause the kind of errors you are seeing, inspite of what some
shrill <people> in this newsgroup might say.

Here I am speaking with direct experience with the HardFrame firmware and the
care and feeding of a pair of them in my hypertrophied A2000. (At one time I had
7 peripherals on one card. *THAT* took some doing to make it work because of
bussing problems.)

Try unterminating the hard drive.  I can only assume that the hardframe 
has SCSI terminator resistors on it.  If it does, you then have 3 sets of 
resistors.  

BTW, what software are you using?

  Rom v 1.9 I'm sorry I don't remember the version of RDPrep.

  Yes I have because the manual says that both ends of the SCSI bus must be
  terminated and nothing else.

  The Maxtor is on the 50pin cable internally the ZIP drive and the CD have
  been on the 25 pin.  I followed the instructions in the manual and used a
  26 pin header with a 25 wire cable wired to a 25 pin connector attached to
  an expansion slot.

  Should I wire things differently?  Maybe take the CDrom out of its case
  and install it internally on the 50 pin bus?
