You mean the platter? It's a kind of metal 'thing' (how technical) that
spans the width of the machine.

If so, then yes. You need to remove it to fit the HD and then put it back
afterwards. I /did/ say it was fiddly.

If you have Ovation, download the appropriate Frobnicate. Pictures included
in that text. Otherwise:

1. Switch off everything, remove the lid.
2. Unscrew and remove all podules.
3. Unscrew the backplane (4 screws) and gently ease it out.
4. Disconnect the floppy disc and harddisc power and data leads.
5. There should be a screw in the middle of the platter, towards the front
   of the machine. Remove it.
6. The platter tilts up at the back, and slides out at an angle. When you
   are holding the platter in your hands, place it back loosely in place and
   figure out where the cables should go for best effect.

The rest is simply fiddling around with the hardware. You'll find getting
the screws into the 2nd harddisc to be, erm, interesting... :-)


My advice to you:
  Once the disc is fitted, put the platter back in place, place the
  backplane into it's socket. Hook up keyboard and monitor and give it a
  whirl. I had to try several times before I got the links sorted (didn't
  have much in the way of paperwork!). As long as the leads are all hooked
  up correctly, you shouldn't break anything by having the drives configured
  wrongly. The computer will pass self-test and freeze (expecting an ACK
  from the harddiscs). Again, the Frobnicate article described my links.

  Once it boots, switch off and screw everything into place.


Good luck. Fiddly but worthwhile.


If you have a drive that runs hot (unusual for IDE) then be aware that the
space between the drive and the floppy is next to nothing. However a well
maintained system will provide airflow across it. Pop out the cover over the
2nd floppy slot and wiggle your fingers in the hole. Feel the air? It's
quite an impressive design in this respect. You may like to give your
computer a clean-out whilst it is open. :-)

Oh, and don't be surprised if it is noisy. The platter tends to act as an
amplifier. I've used some carefully placed bits of window sealing strip. :-)

Maybe you were short on memory?

Depends upon what you need really. :-)
