    I have the same problem and I don't know how to interpret that solution. What is an allocator and how do you commutate it???

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

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.

A540 says "memory card error" " card locked" but 4gb card is not locked - can access card on card reader - copy on and off. a540 works with 2gb sd card no problem. please help?

The A540 works with SD cards. Your 4GB card is actually an SDHC card. While it fits into the slot, it is electronically incompatible and will not work in this camera. You need to use SD cards, 2GB and smaller.

Canon powershot A540 digital ...problem it shown card locked

Remove the SD card from the camera. Look for the tiny slide switch on the side of the card. Slide this switch back to the unlocked position (opposite of whatever its at now).

Try using a card reader until the problem can be resolved with your camera.
Format your memory card once you have the images backed up. Try another memory card to see if it works in the camera. If another one works, it is probably a faulty card, but if it doesn't you may need service for your camera.
Call Canon tech support if this doesn't work.

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).
