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