This has happened to me on a couple of occasions...when you least want it to. I took some photos of my grandson today, only when I went to review them on the camera I get an error message.."File does not contain image data". I took the 32g SDHC card out of the camera and put it in a card reader and get the message"...Can't read file header', unknown file format or file not found. The photos I took yesterday are fine and I can view them.
Has anyone any idea if I can resurrect my photos. The last time it happened I just gave up and re-formatted the card. I do not want to loose any more valuable photos.
Malware can infect removable drives also. Scan your PC for viruses. In My Computer scan your SDHC card for viruses. You should reformat the card. The larger the capacity of the SDHC card, the more bugs you will encounter.
@katyjack@stoksy@crappysailor Fortunately, this is a common problem with an easy solution. There are a couple of reasons it happens, but here is what's going on.
All Nikon cameras have a memory buffer where a photo is stored for a microsecond before moving on to the memory card. This buffer is what allows you to shoot at 3 frames per second, or 5, or whatever your particular camera model is capable of.
The problem is that the camera is not having the time to transfer the photos from the buffer to the memory card. There are a few reasons that might happen.
If you are running low on battery power, the camera might shut off before the buffer is clear. If you are shooting at a high frame rate, you have to leave the camera on long enough for it to clear the buffer (usually 30 seconds at the most). You also may need to invest in a better memory card. All cards have a speed rating (noted by class on SD cards). You may simply have a slower memory card that is not able to write the photo information fast enough to keep up with you.
Do any of these sound like they fit your scenarios when you lose photo data?
Happened to me with another camera. Put a different card in, never happened again. You shouldn't have a problem with the battery thing cos it won't let you plress the shutter once the battery is below a certain level.
Thanks for the helpful hints everyone. I have come to the conclusion that it is a combination of things by the sound of things. As Jason Barnette suggested it could be that I was ''pushing" the camera to do something quicker than it was capable..I did have it set on continuous but will need to check other settings.
This is a new camera and still trying to work out how to use it. As Mac Eugenio also stated that the other thing is the SD card, while it is a Class 6, I think that the 32g is maybe too much. Might try a smaller card size. Glad to hear others though have had this problem, thought it might be something wrong with the camera...seems it could be the operator. lol.
