+ * 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
+ * boundries -- we just mold the disk so that we use the entire capacity.
+ * HPUX also sometimes doen't abide by cylinder boundries, we attempt to
+ * whenever possible.
