It says the memory card is locked but it isn't

If card lock button isn't faulty and doesn't free by sliding it a few times does your camera have a memory lock function in the menu?

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. There are also other common causes if the above didn't help, with troubleshooting steps for this problem listed here.

sometimes while putting the cards back into the device (camera, PC, cell phone, etc) you may be moving the lock. it is located on the back of the card (side without the brand name on it) to the upper right side (with the pins up and facing you) when you slide it up (towards the pins), then it is unlocked.

Be sure the lock isn't locking on either card - that will do it --

First make sure the card is not locked. Do this by checking on the side of the card that the lock notch is not in the locked position. If it is not locked then you should put the card in your computer and reformat it. If this isn't successful then its time to go get a new card. You can get a new one for under $20.

Here's a simply suggestion which I suspect you have already tried.
Many SD cards, such as the the one you see in the picture above, have the "lock". On the left side of your card you should see the lock. Turn the lock off and try connecting it again.
Like I said I assume this isn't your problem (since you know what a "registry" is ;) ) but the problem you described is exactly what happens when the "lock" is on. That's my first advice.
Thanks for using FixYa.

Elementary, Watson. Your SD600 isn't compatible with SDHC cards.

.

Make sure your camera can take San Disk. It probably takes a certian card or the SD card might be upside down. Some brand and models stay this fault and the problem with the SD is that it does not accept a memory card higher than 1GB. This info isn't in the user guide. Have you tried an external usb card reader?

Pull the card out and re-insert. the most likely problem is the card was not seated properly in the slot.

Keep us updated.

Are you sure that isn't "internal" memory card is full message?

Sometimes, when "internal memory card is full" there is no more space in the camera's internal memory. Your camera has 16 MB of internal memory. The number of pictures you can store depends on the picture size setting you have selected on your camera. Keep in mind that the camera always uses internal memory, even if a card is installed (auto default).

If really, the problem is in the "SD memory card", I suggest make some backup all files and reformat the SD. Try formatting it in the camera, there should be a process in your owners manual for doing this; donw formatted SD in your computer, isn't good.

Hope helps.
