Why are all of my photos not being deleted for my memory card?

Question

When uplaoding photos to the computer, repeatedly there are hundreds of photos uploaded. Some of my photos have been uploaded 5 or 6 times. After uploading I use the "erase all" option and it says "deleting" then "no photos stored" however, the next time I try to upload, there they are again??

Answer 1

The card could be on the lock position.  There's a little switch on the SD card.
