Memory Card or Camera?

So I was out at a car show this past weekend taking pictures as usual. I went to upload my card earlier today so I could edit the photos, and a huge chunk of my images had disappeared from the middle of my card. Does anyone know if this is some kind of camera or memory card glitch? The card is a 16GB SanDisk Ultra and the camera is a Nikon D3200

Can they be viewed from in camera? If it can then there is a problem with the memory card.

no it can't

Check if the images can be seen in camera
. Reset the camera
. View the first image
. Decrease the zoom till around 80 images are displayed, and then scroll

If images are displayed, then the camera is able to read them. If some are still missing, then they were either not written or got corrupted.

In case the images are missing, then you can use a data recovery program to see if any image can be recovered.

Your problem may either be the card or the camera. If only some in the middle are missing then most probably you switched the camera off before the image could be successfully written. I find it best to review the images on the display immediately. If I am shooting a long sequence, I review them at the end of the sequence. As the saying goes, better feel foolish checking and rechecking, rather than lamenting lost images at a later date.

did you use it in another camera? is the card completely full? is the card legit. a lot of fake sandisk floating around.

Is it possible that you somehow deleted a day's worth, or a range? Had you actually seen them on the card at some point or is it possible that the images were never written in the first place? No answers for you, sorry.

That sucks! I hope you can retrieve them!
