In raw writing, we write the leadin just like any other track, so..

the disc leadin starts at "d->start_lba", which will be a negative
number and vary from disc to disc.  that leadin runs until lba reaches
-150

every other leadin is 4500 sectors long.

the first leadout on the disc is 6750 sectors long, every other leadout is
2250.

I have no idea whether we can get any status reporting at all while a
drive is writing a lead in SAO or TAO.  (AFAICT, in SAO, we can write our
own leadin, but not lead-out.)
