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