"Well, since this is a tool for experienced users there is not much to say here.\
Most things should explain themself. This page is most useful for notched disk drives.\
Then it will show a few things from several notches at one glance and allow to select the\
notched pages immediately for each notch. The middle button in the top row gives access\
to all pages. Notched pages are marked with a SlateGrey background. All pages are accessed\
with active notch 0.
The numbers on the notch buttons correspond to the alternating sectors for this notch.\
These are sectors that are used for automatic reallocation of bad sectors. The first number\
is the number of tracks that define a zone (0 if there is only one zone) and then the number\
of alternate sectors per zone, of alternate tracks per zone, and alternate tracks per lun\
each seperated by dashes.
Note that none of values shown is reread when you change something\
from this window.
If needed scrollbars will appear to show the whole drawing."
