	The routines commonly used to produce '''bootable''' SD cards (mostly for Linux but also DOS systems for Firmware upgrades) might overwrite these areas. Experience has shown that:
	*bootable SD media perform the intended task well (although speed would depend on class of card)
	*SD cards that are to then be used for second or subsequent bootable images require special pre-treatment - See "Strictly for Geeks" below

	SD cards that are later reverted from use as bootable media to use for general storage might perform poorly in the latter application
