Free File Recovery is a small and easy to use application that will help you to restore files that have been accidentally deleted from your computer.

This includes files emptied from the Recycle bin as well as images and other files that have been deleted by user error from digital cameramemory cards or MP3 players. It will even bring back files that have been deleted from your iPod, or by bugs, crashes and viruses!

hope this helps you

maybe the image format is not supported by the camera, try converting the images in .jpg or .jpeg format.

see if their might be some photos or file saved that you may have edited on the card maybe Microsoft visual studio's photo shop save to hard drive. delete with photo software and format put in camera format again. if it works with computer and not with the camera not compatible try another card

Digital Picture Recovery & Photo Rescue   or   Easy Photo Recovery   or possibly  R-Studio can reclaim your formatted pictures   if you install filetopia  and come to the All Good Things room  i can assist you in getting those software   I'm The_MacGyver

To format the card:
1 Pressing the Erase mode button and the Flash mode
button at the same time sets the screen to the YES/NO
display.
2 Press the OK button to start formatting (the Card error
indicator blinks). Press the Erase mode button to cancel
the mode.
3 When the card formatting is done, the Card error indicator
goes off.
To re-format the card intentionally:
Press the Erase mode button and the LCD monitor ON/OFF
button simultaneously, with the power OFF, to set to the Yes/No display and then press ok.

Yes, try formatting the card within the camera and then check.

to delete photos, you had to have hit 'format' or 'delete'. Changing settings won't do it. IF they are deleted, they're gone. You can't un-delete photos on a camera.
