I was just reading about low level formatting in a book on PC Hardware
Upgrade and Repair. At least some modern drives have lost the ability to
do low level formatting reliably. There is a cost associated with having
precise enough writing mechanism to do the low level format and some
manufactures reduce cost by skipping that step... just allowing the low
level format commands but not actually doing anything. Other manufactures
have cheap write mechanisms which can write to known places but not
provide the precise placement needed for an actual low level format.

The bottom line was that on modern drives a low level format might 1) do
nothing or 2) damage the drive so seriously a factory reformat would be
