Sometimes my unit will not work correctly and would like to know how to get into the diagnostic mode to make sure...

Another reason that a drive will make a "clicking sound" is that the battery is depleted and may have to be charged. This happens when my ipod 5th generation has no battery resources left. Just a thought that may be helpful.

Before reassembly, make sure no wires are sticking out.

Line up top cover carefully. Gently press down on top cover until top and bottom fully seated.

CAUTION! DO NOT PRESS TOO HARD ON THE COVER TO PREVENT CRACKING THE PLASTIC TOP.

GO EASY.

Patience is your best friend.

Do not insert “jimmy in too far. Marking a line from tip upwards on the tool will prevent too far insertion, possibly breaking tabs or damaging internal components.

To prevent the cover closing back up, small strips of matchbook cover (os equivalent) can be inserted about half inch hold prevent closure.

A double sided letter opener or a thin non-serrated butter knife will suffice.

To prenent cosmetic blemishes, place a matchbook cover or similar thin cardboard on the outer perimeter under the “jimmy”.
