Question about Canon PowerShot A540 Digital Camera

1 Answer

When I now try to use a 4gig memory card it always says the card error or card locked. I have tried card in both positions but it still says it is locked. I have tried with 3 different 4gig cards. What can I do? 2gig cards are hardly even available now. Thank you.

You may be restricted to using only SD cards, and many 4gb cards are actually SBHD. My sister had this problem with her camera and by putting in a new 2 gb SD card, her camera worked fine. You may need to shop online in order to find an SD card, but they're widely available online. It costs about the same for 2 2gb cards as one 4gb even though they aren't as convenient.

No matter what card we put in the camera, it always read locked and will not take pictures. please help!!


There are several possible causes for "memory card locked", "memory card error", or "no memory card". The most common cause is having the tiny slide switch on the side of the card in the wrong position. The second most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. There are also other common causes if the above didn't help, with troubleshooting steps for this problem listed here.

Memory Card Locked / write protected error.


Hi due to so many questions asked about this here it is. How to deal with memory card locked/write protected error.


kilgourt.gif



SOLUTION 1 - Unlock the memory card.

There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.



SOLUTION 2 - Toggle the lock switch.

If the lock switch is not on lock:
1. Slide the switch up and down. Repeat this 3 times.
2. Let it stay on the Lock position for 30 seconds.
3. Slide the switch up to unlock the card.
4. Try to transfer files into the device.


For non-SD cards: Format the card

The data on the memory card may be corrupted.

WARNING: Formatting will delete all the files in the device. Backup all your data before formatting.





Memory card write protected, memory card locked, memory card will not read, can't use memory card.

My memory card is showing card locked error. how can I overcome this error? I cannot do the formatting of the card for the formatting option is always hided.


Take the memory card out of the camera and look at it. 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.

Without knowing what the specific error is this is my best guess:

SOLUTION 1 - Unlock the memory card.
There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.

SOLUTION 2 - Toggle the lock switch.

Hello my camera doesnt accept hp 4gb sdhc card.when i placed card in, it says card error.... Also,i cant format when sd card is in and ''card error'' on screen...(my sd cards are brand new) plese give...


Okay we have a problem, to properly answer this question "we" collectively need to know what make and model the camera is. However one clue to your problem was that you said SDHC and 4gb.

I'm going to give you a diagram on the SD card type lock make sure it's in the correct position (not locked) Also the SDHC is a newer style memory card and 4 gig is a ton of memory for point and shoot cameras.

If the card lock thing doesn't work and you still can't format then I'm going to say that your camera can't handle the memory capacity of the 4gig SDHC memory card.

Don't panic yet, you may be able to go onto the camera manufactorers web site sift through the models and find the firmware updates for your camera. Updating to new firmware editions could open the possibilities of using a larger card.
Here is the diagram hope this is all that is needed.

MEMORY CARD ERROR


Camera is not recognizing any memory card. The issue is with the camera electronics and not the cards.

Is that card compatible with that camera. They make HD (high definition) cards (4gig and above) that will only work with newer camera's. Of course, i am speaking of SD cards. But the XD may have a similar feature.
That is the exact error i got when i tried to use an HD card in my 5 year old camera.
Try downgrading to a smaller memory card. Also, is that memory card exactly as the one you have had prior to this?
