On my 3878, to remove the panel that covers the hard drive, one simply needs to slide the panel towards the front of the laptop. Lay both hands across the panel with your thumbs on the front of the computer, press down a bit for plenty of friction, then push with your thumbs.

A crevice/pry tool is not necessary.

Thanks for the guide!
