Fujifilm S1...after taking a picture, the camera will not transfer the image onto the microdrive??

First check with another Memory card. If you have the same problem with another one, remove the card, then check the card contacts inside the camera. They might not conduct properly, if you don't see anytihg out of the ordinary here, then I recomend you contact Fujifilm directly.

If the problem is on one card only, try to format it while inside the camera, then if It doesn't work try to format it on a computer.
If by doing this the card is still not working, it is certainly dead.

Hope this helps.
