(Explanation of Passport log: T00,S00
has a non-standard epilogue -- the one
sector where it's ignored anyway, since
it's read by the disk controller ROM
routine which doesn't verify epilogue
bytes. So they didn't need to make any
changes to the rest of the disk. It's
literally the least they could do.)

Quod erat liberandum.
