The compact flash cards we use have an interface that conforms to some 
sort of version of the IDE 'standard' so they plug directly into an IDE 
interface (with the relevant pin adaptor) - so yes I think it's a fairly 
simple adaptor but I've never opened one up to be sure. Linux treats them 
as IDE hard disks but their hot-pluggability is a bit suspect (we weren't 
able to shut down the IDE interface prior to removal even with hdparm so 
it's probably not even meant to work) and we've killed one or two.
