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