We really do have to be specific around here.

It's just BS, Rob. The fine-wire multipin interface > of the CF cards is well known to be the part that makes them more > unreliable than SD cards in use. Topology when referring to electronic circuits generally refers to the electronic circuit design and has nothing to do with physical layout unless of course the circuit layout is intrinsic to the operation ie in the case of high power or RF circuitry, neither is the case in this situation. Mechanically SD may be more reliable but their inherent circuit design makes them less reliable than CF when it comes to interface incompatibilities as you mention below. > Incompatibility issues with different SD card readers have to do with > the implementation of the controllers.

I don't know how many friend you have or if any even use SD cards, what I do know is that a quick look here and on other digital photo forums confirms my personal experiences. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
