183 * Several HP drives have an odd number of 256 byte sectors per track.
184 * This makes it rather difficult to break them into 512 and 1024 byte blocks.
185 * So...we just do like HPUX and don't bother to respect hardware track/head
186 * boundries -- we just mold the disk so that we use the entire capacity.
187 * HPUX also sometimes doesn't abide by cylinder boundries, we attempt to
188 * whenever possible.
