How Do I fix the card not initialized error - 6 ways

#1 - Turn off and on the camera when inserting the new memory card in your camera

This is an experience reported by user when he fixed the cf card not initialized error by turning off the camera when new memory card was inserted.

I have purchased a new 128MB SimpleTech Compact Flash and later a 128MB Sandisk Smart Media card. Upon inserting them and choosing it through 'Primary Media' on the setup menu I initially received a 'card not initialized' error. BUT.... All I have ever had to do was to turn the camera 'off' RIGHT AFTER changing the 'Primary Media' setting and the card is THEN recoginized by the camera. Additionally, I find it is necessary to turn the camera off/on each time I switch between either installed card.
I believe many of the problems are created when one decides to 'format' the new card (I have never had to perform a format on a new card yet) - I strongly suggest you follow the on/off procedure PRIOR to the 'format' option if you try/buy a new card.
