CoolPix L22: inserted a new memory card, SanDisk SDHC, 4 GB. I get an error message when i turn on the camera: Memory card is write protected. The slider is NOT in the lock position, I've tested the card on my PC and it reads and writes just fine. What can I do so that the camera reads and writes to this disk?

Inspect your SD card carefully. Some SD cards come with a write-protect lock switch on the side of the card. When looking at an SD card from the top there is one required notch on the right side (the side with the diagonal notched corner) and on the left side there is usually a switch. This is the write-protect switch. When this write-protect switch is in the down position (away from the end that is inserted) then it is write protected and read-only. When the switch is in the up position it is write enabled.

the 4800 is a older model that won't support a sdhc card-go back to 2gb or smaller and problem solved-don't waste money on high speed cards for a basic point and shoot camera

Is there a slide switch on the side of the card? Move it to "unlocked" position.

check your sd card, there's a tiny bar on the side that you can "slide" to unlock...

SOURCE: "memory card is write protected"?? but it's not the memory card!

It's not the camera. 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.
