I'm well aware of what a hard drive contains and how it works.
Magnets can still damage them though and its quite unlikely people will have a large enough one or have one
on it while hitting it causing the metal to polarize but damage can still occur with magnets hence my statement.

/edit
Hard drives contain a magnet, aluminum case and stainless steel cover and other parts.
The magnets are made of a standard neodymium iron boron composite (NdFeB).
Neodymium corrodes quickly. To prevent this the magnets are plated with nickel.

Nickel is electroplated onto the magnet, seeing as most data is magnetically sensitive to some degree.
The magnet’s brackets made out of an IRON, NICKEL and MOLYBDENUM based alloy called a permalloy.
Permalloy has a high magnetic permittivity, meaning it will stop most magnetic fields.

The steel casing can be magnetized causing an array of issues.

Not going any further as this was mainly about the Magnet

Been building 20ish yrs always used magnetic screwdriver and never grounded myself really

This minus the 20 years part lol

I would hate to assemble PC's without a magnetized screwdriver.

And never grounded myself either, I do build PC's on wood floor.
