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