Magnetically latching multi-tool holster

Step 4 Retrieve magnets

Your drive should look similar to this, the magnets surround the base of the arm that reaches across the drive platters. Remove the magnet securing screw(s), then use your flathead screwdriver to overcome the magnetic force holding them together and pull out the upper and lower magnet plates. Again, no points for finesse, if that little arm is getting in the way, get a bigger screwdriver and snap it to bits.

You may have gotten unlucky and opened a drive (usually only a very old drive would have this) that uses a stepper motor, it will have no magnets and instead use a little spur gear to move the arm. Throw away and return to step 1.
