I'm not sure how the user notes get attached to the various procedures here, but my comment does seem to show up properly when viewing the steps for Hard Drive Replacement. However, the number of the step may be off if viewed as part of another procedure.

Quote from Don:

I think you may have commented on the wrong page. This page only has 3 steps, and the screws are removed in step 2, not 3.

The two screws removed in step 3 should not be mixed with screws in steps 5 through 7. Though similar, they are actually slightly shorter and have a bigger head. If you put the longer screws back in here when reassembling, the button to unlatch the top will not work properly.
