Judi, The MPower line of notetakers currently do not support the SDHC (high-capacity) standard. The largest SD card available for the BN is 4GB, although those cards have been reportedly unreliable. CF cards, on the other hand, are not limited in this regard, and a 16GB card will function just fine. Email me off-list if you have additional questions.

Have I bought the wrong type of card? Judi ------------------------------------------------------------------------------ before someone else does Find the job of your dreams
