Note : I accept no responsibility for any damage that may be caused by performing the following
operation. It is not an approved Korg modification and is performed entirely at your own risk.
You will need:
• #2 crosshead (Posidriv) screwdriver
16
• 11mm ( / ) socket-spanner or point-nosed pliers, to remove ‘Value Dial’ retaining nut
7"
• small jeweler’s screwdriver or hook, to remove knobs
• hand towel (or similar), to ‘cushion’ the work surface
• grounding strap, to eliminate static electricity
• small container, to keep small parts safe whilst working
Place the hand towel on the work-top, so that the top panel of the D16 is not scratched when it is inverted.
You should take normal anti-static precautions, eg. have a grounding strap connected between your wrist
and an earthed (grounded) contact.
Ensure you will not be disturbed, especially by children or pets.
When you are ready ............
Remove the input trim and the headphone level
knobs. Theyall justpull off but you may need to prise
them withasmalljeweler’sscrewdriverorsmallhook.

The Value Dial knob is removed in the same manner as the trim knobs. Once it is removed you will see the
16
retaining nut for the Value dial encoder, this should be removed with the 11mm ( / ) socket-spanner or by
7"
careful use of point-nosed pliers.
Now turn the D16 over, being careful not to damage the finish to the top of the case, especially to the raised
display surround.
The case is held together with 5 cross-head screws, arrowed. Unscrew them and keep them safe along with
the other small parts already removed.

Lift the bottom of the case carefully. There are two wiring looms that connect the small circuit board in the
lower half of the case to the main mother-board.
The six connectors, marked ‘B’, need to be unplugged. They can be quite tight, but need to be unplugged
gently by lifting each end of the plug in turn until it is released. Fine point-nosed pliers can be useful here to
lift the plug, but make sure you do not pull on the cables themselves.
The flexible ribbon-cable, marked ‘C’, has a different type of connector. This is released by lifting the plastic
body slightlywhich locks the ribbon in place. Once unlocked,thecablecan be pulled easilyfrom the connector.
Remove the two screws A1 and A2, noting that A2 secures a ground wire in place.
You should now be able to carefully lift the motherboard out of the top half of the case. It is attached to the
display panel by a short ribbon cable, which may be unplugged, although it is not strictly necessary to do so.
Note: The cable marked ‘X’ is not a standard Korg fitting. This wire is a result of performing the ‘Aux Send
Modification’ detailed in Brian Smith’s instructions. (The documentation can be found at

On the other side of the motherboard you willfind the
four screws that hold the disc drive in place.
Remove these screws and then slide the drive out of
its connector.
The original drive in my D16 had two small pieces of
adhesive fabric wrapped at the connector end.
These form small, thin insulating shims which should
be transferred to the new drive if possible.
Re-assembly is done by careful back-tracking of the
above instructions.
There may be some grounding washers, (arrowed),
under the disc-drive, (mine had two in place). Be sure
that you do not lose them when installing the new
drive.
Do notover-tighten the screws thatholdthe disc-drive
in place as this can lead to stressing of the
motherboard.

Install the motherboard back into the top half of the case, making sure that all of the connectors are feeding
through and around the circuit board. Refer to the photograph on page 3 for details on the connectors.
Itisworth checking thattherubber button tops (SYSTEM, RECORD, TRACK, etc) are correctly located -they
can become displaced during the process.
You may need to manouevre the motherboard
slightly, to ensure that the LEDs and buttons line up
with the top panel.
Replace allof the ‘B’ connectors, and the two screws,(A1 and A2), remembering thatA2 holds the ground wire
in place. The ribbon cable ‘C’ pushes gently, but fully, into its socket and then the lock is pushed down to
secure the ribbon. Pull gently on the ribbon to check that it is locked in place.
Replace the lower half of the case, and fix in place with the five retaining screws. Turn the D16 over and
replace the Value Dial nut and knob, and finally the input trim and headphone level knobs.
When you power-up the D16 it will ask whether you would like to Initialize the new drive - answer ‘Yes’ and
the drive is configured by the D16 in a few seconds.
Some Disc-Drives that are known to be compatible with the Korg D16 DRS
Manufacturer 40Gb 60Gb Notes
Fujitsu MHT2040AT MHT2060AT All 4200rpm models with Fluid Dynamic bearings.
40 or 60 Gb would seem to be the optimum
choice, keeping in mind the 100 song limit on the
D16.
Toshiba MK4021GAS MK6021GAS
Both Fujitsu and Toshiba have 5400rpm models available, but at the time of writing I have not had any
reports as to their compatibility with the D16.
