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.

    This solved the problem. Another section wanted me to pay 12 dollars if the problem got solved.
    I just bought the camera so I didn't fancy pay 12 dollards.
    Thanks you very much for your help.

Memory card locked

And you looked if the card was locked?
The 64GB card is unlocked the 32 GB card is locked. So make sure the switch is up when you see your card like these two.
When you are sure your card is unlocked, just check if all contacts of the card and in the camera are still clean, shiny, and straight. (no bent in any contact)

I have an canon powershot A490, when I connect it via USB the upload icon does not appear

If your photos are stored on the memory card, then remove the memory card from the camera and insert it into an USB memory card reader. Connect this USB memory card reader and memory card into the USB port of your working computer. Your computer will see this as an USB Mass Storage Device or an external storage device; you can then open the folder on the memory card and copy the photos to your computer. Memory card reader is a handy device and is inexpensive. You can copy photos from other cameras and you can also download photos off your memory card to someone else's computer without the need of installing any programs.

New A490 camera, loaded a new 8GB SDHC memory card, says "Memory card error". Checked to see if I need formatting, but format key is not usable. Can you help?

It's probably a manufacturer's error on the card or the card is locked.
  • did you check whether the card works OK on a computer? if it doesn't, it's likely to be a factory error. If it's new you can probably get it replaced.

  • If it's locked, it can be very easily fixed by yourself.
  1. Turn off cam.
  2. Take out the mem. card. (it's probably located near the battery. press down on it and release it. Then it will pop out.)
  3. Slide the small switch on the side of the card to the position marked with an unlocked padlock.
  4. Put card back in and turn on cam.
There you go. hope that helped. good luck and happy shooting!

My Canon PowerShot A490 has an error "memory card locked" do I fix that, please?

Turn off the camera and take off the memory card. There is a small tab on the upper right side of the card. Just adjust that tab upwards to unlock it. Then put it back and try again.

Hope this helps. Thank you for using FIxYa.

How to fix memory card locked. Canon Power Shot A490

There is usually a little slot on the memory card itself that says lock next to it, and if the card is locked nothing can be written on it. Simply take the card out and unlock it.

I need to import pictures from my laptop to my canon powershot a490 but i cant seem to? help please?!

Be sure that there is at least one picture (just take one) on the memory card. This ensures the canon folder structure is in place. Put your memory card in a card reader. Copy the files from the laptop to the memory card.

For canon, you will see subfolder on the memory card DCIM and under that another folder, something like 136CANON (the 136 could be any number). Put the pictures in that one and you should be able to see them on the canon powershot a490

Memory card error


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
