It depends on the disk. There are 2 bits in indentification data
which tell how it behaves: read zeroes, undefined or undefined-
but-consistent. (The difference between the latter two is whether
one gets the same result if one reads the block twice.)
I didn't bother yet to check what my two disks do.
