It's *supposed* to do a true LLF on a Classic HDD, but I very strongly
suspect (close to certainty) that on modern drives it's a dummy, something
like "write zeros to all logical blocks" as if by ordinary writes.
They probably have stuff like embedded servo (a la RL02) and cannot
be LLFed "from scratch", i.e., from a totally degaussed or misaligned
state.
