I imagine page x3F is an sd issue only?

I remember Ansi says the mode sense header reports writability only for
pdt x00 hdd.

I remember pdt x05 dvd/cd devices misbehaving when their available x3f
AllPages data exceeded the xFF bytes that x1A MODE_SENSE can copy,
though x5A MODE_SENSE_10 worked fine.

And I often repeat, I remember clearly that the popular OS doesn't often
ask only for a four-byte x1A MODE_SENSE header, because I saw that
actually doing that crashes Win 2K kernels up thru SP3, if Windows has
concluded the device needs the host to translate to x5A MODE_SENSE_10.
