http://www.compactflash.org/faqs/faq.htm You can register for free and
download the CF3 spec from there.
If you are just using the CF for mass storage that does not have to be
read by a PC, then you needn't format it with a PC file structure. In
that case it is simply a matter of converting your address to a sector
and offset into the sector. There is a bit less bookkeeping if you use
LBA, but either one is relatively easy.
