XD-Picture Card was created in 2002.

Storing pictures from a camera.

First - stop using the xD picture card immediately, do not take more photos or save more data on that card.

Next - use a picture recovery tool to try recovering the pics.

Lastly - hope my answer will help! Merry Christmas.

Immediately stop using the XD card. Never use the device (such as Olympus voice recorder, Fujifilm camera etc) to take more photos, movies or audio voice memos in case possibility of XD recovery be reduced. Because any operation may lead to data overwritten. Then use XD Picture Card Recovery Software to retrieve the photos.

9 out of 10 times it is whise to let the camera format your xd picture card. but take care xd cards are in M and H types. You should always check the website of your camera if the xd card you are going to use will work on the camera. some older models (camera's ) have probelms addressing cards above 512 MB or check the manual of the camera it should be stated what cards can be used. in case there is no information simply send a email to your brand of the camera to ask it.
