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