This is true. The icon will almost always be located within the drive's
driver software. This can be located from the drive's zero block.
In fact, since the Control() call to the driver to get the icon's
pointer should return the location relative to the driver's beginning,
you could easily compute it's offset, and then probably point right
at it on the disk!
