Use the Chelton Display to format your smart media cards and I will bet they work.

With the IDU-III's, I plugged in a keyboard and kit the escape key. That sent me to a "DOS" prompt. From there you just have to remember your old DOS commands. The XD chip was "E" drive. So type "E:" Then "format e:" Before I formated the XD chip, I typed "dir" and the Chelton read the chip but it was in Arabic or at least that is what it looked like to me. After formatting and reloading the files from my laptop, all was perfect!

I bought two of the adapters as described on the chelton efis pilots web site.  Neither one of them worked.
I bought new smart media cards on ebay, smallest I could find was 128 mb and so far so good.
