Be sure you have formatted the card, not the internal memory (if the camera has that).
Be sure your battery is fully charged, so that the device can fuly write the file.
Be sure you are writing the file to the card, and not the internal memory, as there may not be enough space on it to write the file.
If this does not resolve the problem, let me know.

Hi there, do this:
To fix this, remove the SD card from your camera. Look on the side and you will find a little switch. One end of the switch says locked the other end says unlocked. Move the switch from locked to unlocked. Replace it in your camera and turn it back on.

Thanks for coming to FixYa and fee free to rate my solution.

This is the classic symptom of a failed CCD sensor. The only fix is to have the sensor replaced, but as the camera is around six to seven years old now any repairs will not be cost effective and you will likely have trouble sourcing the parts as Fuji stopped making their 3MP sensor many years ago. New, old stock sensors may also have degraded to the point where they are either faulty straight out of the box, or will develop the same fault within a few months of being powered up.

Sorry, but your camera has reached the end of it's useful lifespan: five years is pretty good going for any digital camera and six to seven is really exceptional. Digital cameras simply do not last anywhere near as long as many of the film cameras which they replaced.

Your only real choice is to buy a replacement, but if all you need is a similar technical specification to your current model then there are plenty of cameras for less than £100 (around $175 in OzDosh) which will do at least as good a job as your present camera. Just don't expect a sub £100 camera to last anywhere near even five years though.

One other advantage of an update is that you'll finally be ditching the expensive and highly inferior xD memory cards which were basically repackaged and slightly tweaked SmartMedia cards. If you buy a new Fuji then you'll find that they all take SDHC cards now (back compatible with SD cards) although they often still accept xD cards as well.

Sorry I can't be more positive, but I hope that I've still helped you. All that I ask in return is that you take a moment to rate my answer.
