Re: no memory card message

Check to see if any of the little pins that make contact with the card may be damaged, bent, broken or dirty. If you shine a light in there you should be able to count them. compare to the slot in a different camera where you know it works. If it's only bent out of shape you might be able to bend it back, but it would probably void any guarantee you might have left.

Canon PowerShot SD400 No memory card message, but there is a memory card installed. Tried multiple memory cards and got the same message. Made sure the memory card was locked.

There are several possible causes for "memory card locked", "memory card error", or "no memory card". Some include trying to use a 4GB SDHC card with an older camera made before SDHC format came out. Others include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card). Troubleshooting tips for this problem may be found at this link. By the way, if you're using 4GB or larger SDHC cards, they won't work with the SD400 as that camera was made before SDHC came out. Consider 2GB or less standard SD cards only. They're very inexpensive these days on Amazon..

I have just installed a 4 GB Sandisk in my new Kodak Eash Share C195 camera and it keeps giving me an error message - "Memory card is protected, Reset switch on memory card" I saw only one switch...

A couple of things you might want to try the little lock on the side of the memory card should be in the unlock position. If you are still getting the error message then shut off the camera and remove the battery and the memory card. Insert the battery after about ten seconds should and install the memory card then turn the camera back on. Format the card in the camera NEVER format the card in your computer, format the card over deleting single images. If this camera is new, new then you should have the instruction manual or may be called the owners manual look for formatting instructions, every digital camera has a format feature to clean the memory card. Now if all this still doesn't work you may need to update your camera software. My Canon Pro camera gave me a headache when I went from a 4 gig to an 8gig card it just wouldn't acknowledge I even had a card in the slot. However you may just need to hard boot it after switching the memory card to the unlock position. Don't forget to format the card. Robert

Memory card is locked, how do I unlock this?

Problems typically are pretty rare with Panasonic Lumix digital cameras. On those occasions where you do have an issue, though, look for an error message on the Panasonic camera for some clues as to how to fix the problem.
he seven tips listed here should help you troubleshoot your Panasonic camera error messages.
  1. Built-in Memory Error error message. If you see this error message with your Panasonic camera, the internal memory area of the camera is either full or corrupted. Try downloading photos from the internal memory. If the error message continues to appear, you may need to format the internal memory area.
  2. Memory Card Locked / Memory Card error message. Both of these error messages are related to the memory card, rather than the Panasonic camera. If you have an SD memory card, check the write protect switch on the side of the card. Slide the switch up to unlock the card. If the error message persists, it's possible the memory card is corrupted and needs to be formatted. It's also possible the memory card was formatted using another device that is not compatible with Panasonic's file structure system. Format the card with your Panasonic camera to fix the problem ... but keep in mind that formatting the card will erase any photos stored on it.
  3. No Additional Selections Can Be Made error message. If your Panasonic camera allows you to "save" photos as your "favorites," you may find this error message because the camera has a limited number of photos that can be labeled as favorites, usually 999 photos. You cannot mark another photo as a favorite until you remove the favorite label from one or more photos. This error message also may occur if you're trying to delete more than 999 photos at one time.
  4. No Valid Picture error message. This error message typically refers to a problem with the memory card. Most of the time, you'll find this error message when you try to play back images from the memory card and the memory card is corrupted, empty, broken, or has been formatted with another camera. To fix the memory card, you must format it, but formatting a memory card causes all photos stored on it to be lost. Try inserting the memory card in another device or in your computer and try downloading any photos stored on it before formatting it with your Panasonic camera.
  5. Please Turn Camera Off And Then On Again error message. At least this error message says "please." This error message most likely occurs when one of the parts of the camera's hardware is malfunctioning, usually a jammed lens housing. To try to fix this problem, start by turning the camera off for a few seconds before turning it back on. If this doesn't fix the problem, try resetting the camera by removing the battery and memory card from the camera for at least 10 minutes. Replace both items and then try turning the camera on again. If the lens housing is jamming as the lens moves through its zoom range, try gently cleaning the housing, removing any debris or grime. If all of these steps don't fix the problem, you'll probably need a repair center for the camera.
  6. This Battery Cannot Be Used error message. With this error message, you've either inserted a battery that's incompatible with your Panasonic camera or you've inserted a battery that has dirty contacts. Gently clean the metal contacts with a dry cloth. In addition, make sure the battery housing is free of debris. You sometimes may see this error message if you're using a battery that's not manufactured by Panasonic. If the third-party battery is working OK to power the camera, you probably can ignore this error message.
  7. This Picture Is Protected error message. You'll see this Panasonic camera error message when the photo you've selected has been protected from deletion. Try working through the camera's menus to figure out how to remove any protection labels for the photo files.
Keep in mind that different models of Lumix cameras may provide a different set of error messages than is shown here. If you are seeing Panasonic camera error messages that aren't listed here, check with the user guide for your model of Panasonic Lumix camera for a list of other error messages, or visit the Support area of the Panasonic Web site.

Samsung SL620 - - "Card Locked" message

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.

My digital camara will not save pictures. Messages appear.

If you are using SD memory card, it can be locked. Take out your memory card, on the left side there's a switch. Turn switch up and try again. Hope this will work.

OK, if the memory card itself is locked, you might sometimes get this error code. All you need to do is to take out the memory card and switch the lever on the left side to the unlock.


If the error is still displayed after you did the above, you might want to try the card in another camera.

If the card works in another camera . the problem is with your card reader in your camera.

If you open you sd slot and look inside with a sharp light , you should be able to see on the left side of the slot there is a little copper or spring steel lever switch. This switch work as follows:

1. When no card is inserted / no write protection , the switch is open and thus the protection is off.
2. When locked card is inserted , the tab is depressed and tells the camera that the card is lock.

Contrary to popular belief ,the little tab on the sd card is not an electronic switch and does not physically influence the card operation itself. If you put a locked card into a camera without a sd lock switch , you would still be able to use the card normally.

It is incredible difficult to fix this switch because of space limitations in the sd card. Look into the sd slot and if you can see the switch , use a needle to pull the little tab down toward the base of the camera by about 2mm or until it works being careful not to bend it.

If this does not resolve your problem , there might be a short in the switch circuit and the camera will need to be disassembled to resolve this error. This should cost no more than $50.

Please feel free to contact me if you need further information

Kind regards

"Memory card is locked

This error message means that the memory card is write-protected. To take a picture, turn off the camera. Then insert a new card or change the storage location to internal memory.
