Hello, How do I format my Lumix camera card? I have a folder on it called "found" that I cannot delete. thanks

First : is it the same to other SD Card?If yes thenSecond: is it happened to other SD Card?if the second answer is YES -> it might be the I/O part of the camera
but if the second answer is NO -> try to re format that SD Card it might contained a faulty fat (file alocation table)I hope it help

Actually, you still might be able to get those photos back, even though they've been erased. Try not to take any more pics until you've recovered your photos, take the card out of the camera. This is to reduce the chance of you overwriting some of your "lost" photos. There are many good freeware photo recovery software options that may help you recover your photos. This article reviews and outlines several of the better ones.
This sounds like the problem may have occurred because you might not have formatted the card in your camera as recommended by the manufacturer. If true, after you've recovered your photos, format the card in your camera using the camera's format feature. This will prevent this from happening again.

If you do a complete format of the card, that should do the deed.

Look at the memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

I recommend against deleting images on the card via your computer. If you want to delete a few pictures, do it from the camera. If you want to delete all of them, format the card in the camera instead. FixYa is full of people asking how to salvage pictures from cards which have undergone repeated write/delete cycles without formatting.

Hello and Welcome

The DCF error message with your Samsung camera nearly always occurs when you're using a memory card that was formatted with a different camera, and the file format structure is not compatible with your Samsung camera. You will have to format the card with the Samsung camera.However, make sure you download any photos to your computer first

Anymore help, I am here to help
Best of Luck

If you've deleted the DCIM folder, make sure you format the card in the camera.

Move the slide switch on the side of the memory card to the unlocked position.

Sounds like a MobileMate quirk Tanya. Use your USB cable connection to your PC/Camera interface and delete pics that way too see if this funny goes away.

If it does, and I believe it will, then it is a SanDisk issue not revising the File Allocation Table(FAT) after deleting the Pic File on the mem card.

You could also find out if this is just an SDHC SD card reader issue by using an older less dense standard 1 or 2Meg non-SDHC mem card in the reader and see if issue goes away.

The fallback of course to view and delete the pics on the camera before download, or download pics then note which pic file numbers you want deleted after viewing on PC, then put SD card back in camera and delete them there.

Another option for trial, is to cut and paste the whole DCIM folder, or sub pic folder to your PC from off the SD card using the card reader. The camera automatically generates subfolders under the DCIM folder if you completely remove(deleting by a cut or move), when you take your first picture on a camera with a DCIM but not sub pic folder. Try this first and I think you will find all pics will be deleted from camera that are in a subfolder under DCIM. If not, then cut or move the whole DCIM folder and create a new DCIM(empty) folder on the SD card using the PC and card reader. Of course using this method you cannot selective delete individual pics from the mem card. You would be deleting them all after the Folder cut or move from the SD card.

I don't have a solution to the first part of your dilemma (why it won't playback) but I do have a solution for deleting the file.  On your camera are "hidden" file folders.  When you connect your camera to your computer, you probably only see two folders (that's all I see for my DMC-LZ8).  But there are more, and your undeletable picture/video is in one of these folders.  Find the folder and you'll find the file.  Delete it from your camera using the computer to do the command.  Problem solved.  Okay, so how do you find the hidden folders?  I have a Mac, so my process was this:  1) Connect camera to computer; 2) Select/open camera icon (looks like "volume disk"); 3) From top Finder bar, select File then Find;  4) Select the camera volume to limit your search to the camera (not HD or other external hard drives you may have connected to your computer); 5) Select "Kind" and in the next dropdown button "Folders".  Voila.  Happy searching.  My hidden "undeletable" video files were in a folder called "100_PANA".  I selected them then moved them to the Trash.  Be sure to eject your camera properly (don't just turn it off or disconnect it).
Good luck.  I hope this helps.
PS - My theory is that this occurred after an upload to my computer got unexpectedly disconnected before everything finished loading or else the camera got disconnected from the computer incorrectly even if the upload had already finished (see above comment to eject camera properly).  In either case, the blank/black screen, unviewable but "there" on the camera taking up memory photos/videos problem happened to me, too.  The above actions resolved it for me.
