My memory card is locked - SanDisk 1GB microSD Memory Card

Oops. The little latch on the side in the unlock position, should engage a switch in the camera, indicating the memory card is not writ protected. It is not an electrical switch doing something in the memory card. But is the switch in the camera is defect, you get the same result. If someone once tried to press in a memory card, the wrong way around, this could have been the cause of a damaged switch. Just check the memory card slot, of nothing is in the cardholder, blocking the little switch from working correct. Sure the switch is in the up position, like in the picture?

Locking the memory card prevents you from taking and adding photos to the memory card. It also prevents you from deleting photos from the memory card.
If you want to erase all the photos off the memory card. unlock the memory card, go to the camera's Menu and scroll through the settings ti Format the memory card, then format the memory card.

i cant to delete files from my memory card

I don't own this camera but My guess is your memory card is in a LOCK SETTING you need to move the memory card to unlocked " wrirte " so you memory card isn't locked.....
Step 1 remove the card from you're camera
Step 2 there is a small little side on the side of the memory chip move that to the unlock position.
step 3 insert the card and start shooting!

Hi Aditya,
Use the following link to lock folders of your memory card

I use a Nikon D300 and have Sandisk Compact Flash memory cards. i ahve not come across this problem but would suggest that you insert the memory card into your camera and reformat the memory card. This should clear any errors in the system BUT IT WILL ALSO WIPE ANY PHOTOGRAPHS YOU AHVE TAKEN when formating the memory card.

I had the same problem - just put the lock button of the card to the lock position and than again to the unlock position

I noticed that this camera does not work well with cheaper memory cards. The only brand that works without fail is the SanDisk brand.
