Image Does Not Contain Data on Nikon D3000?

I deleted about 200 pictures from my camera via my computer, rather than deleting them straight from the camera. Now, all I see is, "Image Does Not Contain Data," for about 200 pictures worth of spots. How can I get rid of this, without formatting the camera?

You are always supposed to format the memory card using the format feature on the camera after successfully copying all the images from the card to your computer.

Using your computer to delete things from you memory card, is a sure way to cause corruption of the card.

In the future, copy all the image files to your computer to a new file folder named for the subject and date. Sample: evergreen052012.

Once safely there, format the card using the format feature on your D3000

Do this at the end of each shooting day.

NOTE: It is much better to use a card reader than the USB port on your camera. It is faster and does not require you to use the battery power on your camera

You can't! Format the card on the camera - where is the problem - you have nothing there to delete except damaged data - the photos are long gone.
