Changing out the 100MB Zip drive for a 250MB Zip drive
Obviously: Disconnect the power supply and all other cables from the SP. Observe the usual
precautions about electrostatic etc. As you disassemble the SP, keep the screws in three separate
piles as you remove them. Prepare places beforehand for all three sets so you don't lose them or
get them mixed up. Turn the SP over and rest it on something soft and pliable, like several towels,
so that the knobs on the panel are not subject to unnecessary pressure.
(1) Remove all the screws in this order:
a) Removing the SP's bottom plate: Remove the 13 screws on the bottom of the SP. Do not remove
the two screws in recessed holes at the top; these can stay put.
Don't forget the interior screw just above the middle rubber foot at the bottom. Note that not all
holes have screws in them (at least on my unit).Lift off the bottom plate; it should slip off easily.
Put it aside in a position allowing you to remember which way it fits.
b) Removing the Zip drive housing/frame from the inside of the SP: [I found it easier to remove the
power cable and ribbon cable from the old Zip drive itself if I first removed the screws holding the
Zip drive housing/frame to the inside of the SP, it's just easier to get a grip on the cables.] Remove
the 5 screws attaching the drive housing/frame to the inside of the SP (2 on the right, 3 on the left)
the screw on the upper left is a little hard to get to if you don't have small fingers. When you've
removed these screws, the housing/frame still won't come out all the way because the cables are
still attached to the Zip drive inside it.
c) Removing the Zip drive itself from the drive housing/frame: The Zip drive itself is attached to the
drive housing/frame with 4 screws, all on the top of the housing. Remove these screws and put
them aside. The Zip drive will now be loose, but because it still has its two cables attached, you
can't lift the Zip drive all the way out.
(2) Remove the two cables connecting the old 100 drive with the SP innards:
a) the power cable (You will want to reattach it to the 250 drive the same way it was attached to
the 100, so leave it in a position that makes that easy to remember.)
b) the ribbon connector (Same as above, though the fit inside the SP is so tight, this connector will
remain pretty much in the same position.)
(3) Remove the old 100 drive from the drive housing.
(4) Put the two drives side-by-side for comparison and install the jumper into the 250 drive to set it
to Master just the way it is already installed in the 100 drive. The drive comes from the factory set
to slave. On the back of the Zip drive, between the ribbon cable port and the power-cable port,
there are three rows of two pins each. If the Zip drive is lying on its back, the power cable port will
be on your left, and the ribbon-cable port will be on your right. The three rows of two pins each will
be between those two ports. You'll see that the first row of two pins on the left is covered by a little
jumper. This jumper should have come with your 250 Zip IDE drive (mine came in a little zip lock
plastic bag). If you're unsure, you can hold the jumper up to the one on the back of the 100 drive
you just removed to see how it will fit onto the two left-hand pins on the back of the 250. Slip it
onto the two left hand pins on the back of the 250 to cover them. Press firmly till it is seated. This
sets the Zip drive to Master. The backs of the two drives should now look the same. Now the whole
process is exactly reversed: slip the new 250 drive into the drive housing/frame with the cable ports
to the back.
(5) Reconnect the two cables to connect the new 250 drive with the SP innards (a bit easier in the
following order):
a) the ribbon connector
b) the power cable
