This is pointless, anyone can look on the bottom of their
drive and a large percentage will see there is no tab. They
aren't even sunk on the underside to the copper either, at
least none that I've aware of and I ALWAYS examine drives.

This proves that you know little or nothing about how transistor and
FET packages are made. It also shows that you are a mere observer, not
an engineer. "I ALWAYS examine my drives." Whoopie doo, little boy.

You have proven that you know nothing about how dissipative devices
are made, let alone how the die is thermally coupled to the
packaging... ALL of the packaging.

And yes, a hard drive's PCB assembly uses conduction cooling
methodologies to manage thermals generated by driver devices.

Both those for the spindle as well as those for the head actuator,
and read/write head(s).

You truly are clueless.
