My memory card is saying that it is write protected what do I do?

Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

If that doesn't work, try another card.

To remove write protection
In your memory card adapter have a switch to on/off write protection.

pull this switch to down ,you can remove write protection of your memory card
thank you

Some memory cards are having a write protection switch integrated on the side or on the back of the memory card for preventing the content from being erased or overwritten by accident, just like floppy disks. Both SD Memory Card and xD-Picture Card have their write protection switch on the side of the memory card in contrast to the Memory Stick PRO and some Memory Stick Duo that have their switch on the back of the card.

The SmartMedia Card is also supporting write protection but not with a switch. For protecting the SmartMedia Card's content you need to put a sticker on the card's write protection pad. It is the circle that can be found in the middle of the card, when facing the front of the card.

On the side of the memory card, there is a small slider that locks and protects the memory card from being overwritten. Yours may be in the locked position. Simply pull out your memory card form your camera and unlock your memory card by sliding the tab.
Hope this helps,

Kindly follow the steps below

Remove the memory card from the camera.
Look at the memory card very well, you will see a slide switch on the side edge of the memory.
Move the switch to the unlock position.
Put the memory card back to the camera.
You can then start using it.

Thanks

Take your memory card out of the camera and switch the position of the little "lock" tab. That should fix it and you can start saving images.

When I try to delete the files Kingmax 1GB Micro SD Memory Card it says that The disk is write protected or insert other disk

Try to lock down the little switch on the memory card.
good luck!
