I just finished my third and easiest build of a stir plate. I am following these directions.https://www.homebrewtalk.com/f51/my-stirplate-cheap-easy-build-86252/
what made this one easier is that I could not find a bit small enough to take the hard drive apart so I had to literally pry and bust em open. WALMART has this little kit that has exactly what you need to just disassemble the hard drive right down to taking the magnets out. I know every dribve is different but so far I have taken apart 4-5 of them and every one has the same size star bit that I could NOT find. Anyway the kit is less than 7 bucks.
ALSO when removing the magnet from the bracket, THEY WILL BREAK very easily. PATIENCE is key. If you do break em don't get too panicky they will still work.
