Make sure your Xbox is safely unplugged and is laying on a flat, stable surface.

Turn the Xbox over to reveal the four rubber feet.

Use a metal spudger to pry off the four rubber feet.

There are 2 more screws hidden under the two labels on the bottom of the case.

You can either remove the labels or simply feel for the screw holes through the labels and then cut or punch a hole through them.

These labels are "Tamper Resistant" and will usually reveal a checkerboard pattern when removed. To reduce the likelihood of this happening, use a hair dryer or heat gun to warm the labels and soften the adhesive first. The pattern may still appear, however it won't be as bad.

Remove the six T20 Torx screws securing the top cover to the bottom cover.

Wedge a metal spudger and carefully pry upwards to slightly separate the top and bottom covers.

Flip the Xbox right side up.

Hold the sides and lift the Xbox slightly off the bench. A gentle shake of the unit should see the top cover separate from the rest of the unit quite easily.

Placing the Xbox on your lap while separating the top and bottom covers may make the process easier.

Once the bottom and top shells are no longer attached, carefully turn the Xbox right-side-up, lift and remove the top cover.

Remove the three 3 mm T10 screws securing the hard drive to the Xbox.

There is one screw on the rear left side of the hard drive that is only visible when the IDE ribbon cable is lifted up. The other two are at the front right and left sides of the hard drive.

The screw on the lower left corner of the disk drive is not in the hole that it appears to be in, but rather just closer to the corner.

Free the hard drive power cable from the carrier for sufficient slack to lift the hard drive out.

Lift the plastic hard drive carrier out of the Xbox case.
