Sandisk is On card lock???

Yes and no. According to the manual the S630 will work with SD cards up to 2GB in size and with 4GB SDHC cards. If the cards at the store are actually SDHC cards (most likely since 4GB SD cards are very rare) then they should work fine.

It's not the camera, it's the 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.

This is likely happening because your cam's memory card is corrupted. This is common with SD memory that has been used extensively for a long time and it's likely not caused by any fault in the camera.

You can try formatting the card but this isn't likely to work really. You will have to buy a new card. Make sure you buy a good brand like Lexar or SanDisk. Good luck. Hope that helped.

If you remove the card from the camera and connect the camera to your computer with the USB lead, you should see the camera's internal memory as a disk drive on the computer. If there is a memory card inserted, you will see that memory instead.

Unlocking individual pictures is done with the same function that locked them. It is probably on a menu available when you are viewing the pictures on the camera.

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.

If you transfer the photos to your computer from the camera, you should be able to save to another memory card. I can't say whether or not the photos on the new memory card will show up on your camera since there may be certain requirements to display on camera screen.
Plug your camera into the computer USB or insert old memory card. A box should pop up giving you the option to view files. Copy and Paste (or Drag) selected photos to a specified folder on your computer (Like My Pictures in My Documents). Insert new memory card. Copy and Paste (or Drag) selected photos to the drive for your memory card.

If the card is locked, you could the steps below:

- Turn off camera
- Remove memory card
- Take a look on the switch of the memory card itself
* If it's at the TOP = card is UNLOCKED
* If it's at the BOTTOM = card is LOCKED

- So, you just have to make sure that the switch is at the top
for the memory card to be UNLOCKED

After doing that, you just have to put back the memory card to your camera and turn on the camera. Try to check if this works.

you have several options:

1. see in the specification details of your camera what memory card is compatible for camera. for S630 it is SDHC/MMC/SD card (Up to 4GB Guaranteed). see if you're using memory card within this capacity and type. If you're using a different memory card type and capacity, try to use memorycard that is compatible with your camera.

2. try to use memory card to other devcie like cameras, cellphones and other devices and if it still has error problem, your card may be the one defective. use other cards.

3. try to take pictures without using memory card. use only the internal memory of camera. if camera still display this error meassage, camera needs service.

hope these options solve one of your problems. c",)

About the memory cards to be used with this camera, those could be:
- MMC / SD card (Up to 2GB Guaranteed)
- SDHC card (Up to 4GB Guaranteed)

Some cards are not compatible according to the memory card
manufacturer and memory card type.

If that is the case, i'll be advising you to try 1 GB so it will work.

But if it still does the same thing with the 1 GB card or with whatever cards you're using, you could still take more pictures even without a memory card. It's just that you need to adjust the picture size and quality to the lowest resolution to have more pictures taken.

To change the size:

Rotate the mode dial to PROGRAM:
- Press +/- button (2nd button)
- Go down to where you're see 6M, 5M, ... 1M
- Select 1M for the lowest size
- Press MENU/OK to save changes

To change the quality:

Rotate the mode dial to PROGRAM:
- Press +/- button (2nd button)
- Go down to where you're see Dots corresponding to NORMAL, FINE and SUPER FINE
- Select NORMAL for the lowest quality
- Press MENU/OK to save changes

To turn off camera after the settings
have been changed to refresh the camera.

If it still does not work, you need to contact the Manufacturer.

I hope this help you a lot.

normally a gentle 'push in' releases it allowing it to pop up. Except Compact flash that have a release button near by What type is yours.
