Wall CLOCK from Old Hard Drives

Step 2 Disassembling Hard Drives

First of all you have to undo screws as shown in picture below, after that you'll be able to remove one or two shiny disks (platters) and some thick aluminum washers.

Underneath you'll find Hard Drive Motor, this usually attached to HDD case using 3 screws.
You can also disassemble Actuator Mechanism, there are 2 very powerful magnets for your future projects.
