Well, according to scsiformat, the sector size *is* changeable.  I've
gone through all four -P values, and discovered that the default value
is, in fact, 512.  Obviously one alternative would be to reset the disk
to its default value.  Does anybody have any ideas on that?

-P 1 (changeable values) lists all the fields, but all are set to 0.
Does this mean anything?
