Not every scsi disk does support this at all nowadays - remember, you need
a couple levels of forward error correction and n-out-of-m-bit encodings to
see any meaningful data with modern bit densities, so the user-visible block
size is probably fixed.
But some media are !=3D 512 - some MO use 1024 bytes, some 2048 bytes.
CD in data mode also uses 2048 bytes.
