Have tried using the strongest cuboard magnet I can find (In north
London u.k.), but if the wind picks up surprisingly it will just not
hold. Also

The magnet out of a hard drive is flat and very strong.

Really? What kind of hard drive has a big flat magnet inside? That defies
all logic on the principals of how a hard drive works.

All hard drives, the head arm solenoid uses them. My shed's full of
magnets from HDDs. For example I use them to store sash clamps out of the
way on the ceiling. I've used one from a larger mainframe disk drive to
fish 37lb sash weights from a skip, you've just got to make sure it
doesn't touch the side of the skip.

Sounds like trying to get a prize out of one of those crane machines! )
