Lost files on a SD card
I have a Canon Power Shot using a SD 4gd card to take pictures. I accidentally popped the card out of the camera and then put it back in. Now all of the pictures I took before do not register on the camera memory. Does the card overwrite pictures if this happen.
When you delete pictures (or any files) from a memory card or USB memory device the data itself isn’t deleted, just the file system pointers that says where the data for those files is located. The area where the deleted picture data was stored is also now marked as free space so it is available to the system for any new files to be written there instead.
If and when that happens, then it is too late to recover your deleted pictures so it is very, very important that new pictures or files aren’t saved to the memory card in the meantime.
One of the easiest ways to see if your deleted pictures can be recovered is to try some photo recovery software.
One tip is to try a demo version of a commercial product that will scan the memory card for deleted pictures and show you exactly what pictures can be recovered. At least that will show you if you can recover the deleted pictures or if it’s too late already. You can find more useful information on how to recover deleted photos from a camera memory card here
