heard from some sources that nothing is ever completely gone and No Such

I have a hard time believing that one.
I can believe that the data can still be recovered, but I would guess
that it would take some pretty specialized equipment to measure the
magnetic field accurately enough to recover data from a formatted disk.
I would guess that the hysterisis in writing to the disk would leave
some tell tale signs of the data that was erased.
