When putting a Lexar Multi-Use 16 GB SDHC memory card in my Canon Powershot A540 I get Memory Card Error message as well Card Locked message. Have tried unlocking it by the slide on side of card, is t


It's a lost cause. The A540 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in devices not designed for them. You need to stay with SD cards, 2GB and smaller.

I have a Canon PowerShot A540 Digital Camera I got a new memory card it is a sandisk SDHC 8 GB but I am getting a memory card error message.... What can I do?


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. Please note that your particular model camera can only use up to 2GB standard SD cards. These are relatively inexpensive these days, and may be purchased on Amazon if your local store no longer carries them. There are also other common causes if the above didn't help, with troubleshooting steps for this problemlisted here.

My memory card is locked and i tried everything i have a canon a540 powershot and the memory card is a sandisk 8gb


Have you noticed the slider on the side of the card? This acts as a lock and might have been accidentally moved to the locked position, in which case you could just move it back to unlock again. Hope this helps.

Canon powershot A540 I have tried to erase memory card but it says card locked. How do I unlock.


Look at your 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.

Memory card locked. Will this camera support SDHC cards or just SD cards


The A540 uses SD cards, not SDHC cards.

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.

If you've already tried the lock/unlock switch on the side of the card, then see this link for additional troubleshooting tips for this problem.

Memory card locked


When this problem occur you need to set the memory card unlock or not protected. Remove the memory card from camera and you can see a small button in the memory card, so you need to slide that to set the memory card unlock or not protected.

Inserted new sandisk ultraII 2gb into camera. error message, disk locked. unlocked, still error message


Hi!
Does it work with other cards? There's a small switch on the memory card reader inside the camera which tells the camera that the card is locked. Most likely this switch is broken. You can try to point it with needle or something but I'm afraid you will have to give it away for a repair to a local repair shop or Canon service center.

There's a little switch on the side of the SD card. Remove it from the camera and find the switch. Normally, there's some very small printing next to it saying something like (Lock / Unlock).
