Nuts, forgot to add my own prefix again.  Twice in one week.  Ouch, sorry.

	By the way, as a point of personal privilege ...

	Offline I was told people have been saying RBC came from Pat.

	Not true.

	Three points in my defence:

	1) Yes the RWFL bits came from Pat et al.  Last I
	checked, those bits never made it into any merely
	public standard.  Last I checked, this lack is still
	causing real trouble in the real world: Windows works
	best when we pretend insert & eject don't take time.

	2) Rumour - or baseless slander - says RBC suffers
	from the kind of binary incompatibilities designed
	into the SFF vs. ANSI vs. USB Boot redefinitions of
	SCSI CDB's and data.  As far as I know, I have never
	created and I have never willingly perpetuated any
	such incompatiblities.

	The fact that I don't know how binary incompatible RBC
	is or is not testifies to me not knowing it well
	enough to have invented it.

	3) Thinking that mode page 5 contained C:H:S was my
	error.

	Mode page 5 contains H:S:C instead, of course.
	"Everybody [but newbies who read nothing but merely
	public specs] knows that."  I have NO IDEA why.

	Me, when first I saw that the page did not contain
	C:H:S, I somehow got the idea it contained precisely
	the field-reversed S:H:C rather than the one-field
	left-rotation H:S:C.

	Because, back then, I had never disassembled a
	standard Microsoft Lba 0, I didn't understand why a
	SCSI device wanted a PC C:H:S geometry anyhow, so when
	I saw H:S = x20:40 for 100e+6 B, I didn't know at a
	glance how wrong that was.

	I was also innocent of the legacy that says maxH:maxS
	is xFF:3F, so again x20:40 is wrong at a glance.  As
	far as I know, that legacy has never seen the light of
	a merely public standard either.

	Happy Thursday, Pat LaVarre
