Really? What kind of hard drive has a big flat magnet inside?
Most modern ones that use voice coil positioning for the heads.
That defies
all logic on the principals of how a hard drive works.
Cunning design (the N and S poles share the same face) and a bit of
shielding keep the magnetic field contained and the platters safe.
Any idea what that shield is made of? it looks like aluminium, but
isn't.
