Question about Canon PowerShot A1100 IS Digital Camera

1 Answer

Card locked but it's not? What can I do.

I have even bought new SanDisk cards but it still says they are locked but they aren't. It must be the camera at fault. Any ideas?

    How annoying and I have just bought 2 new ones! Will see what my manual says although my old card was the same as the ones I have just bought so they should work too. Very strange.

Oops. Later read what my first thought was. Forget that is what comes first means anything to you.
Your camera is not that young. You only can us SD cards. It is very difficult to buy them.
If you bought a 4GB card you definitely have a SDHC card and your camera can't work with that. Today even lots of 2 GB cards are already SDHC. I know if you look good, you could fine a 4GB SD card. I have bought some recently. Look for Platinum 4GB SD Card.
Still if you are sure you do have a 1GB or less SD card, read what is next.

Looks this is not on the card, but in the camera. It could be the switch that sees if you "Locked" the memory card is pushed by something else. I'm not sure if you could see that, with a magnifying glass perhaps and some extra light? Look in the memory card holder, if you see something strange. And only use some pressed air (never high pressure, because you could blow up your camera) A technician cold go a little farther, and open the camera. to check is there is no corrosion in the switch(es). But before you go out for a repair, I think you could buy a camera with better quality pictures now, for probably less money than repair would cost

SOURCE: Loaded new memory card, and screen reads memory

I'm guessing you bought a new 4GB SDHC card. Although it looks exactly the same as a standard SD card, the format the card uses is very different. If your camera is more than a few couple years old, it's likely it was designed before the SDHC format came out. Sorry, but a SDHC card will not work with older cameras.
For older cameras, you'll need to use standard SD cards (usually those 2GB or less). But if you really want to use a 4GB card, do a Google search for 4GB SD "non HC", with the non HC in quotes. Believe Transcend makes one.

There should be a small toggle along the end side (it is tiny and easily missed, but it is there, I just checked my memory card / mine is 4GB SD card from Sony) that you can swtich to unlock and your images may come back that way.

Look for it this way, hold the card face down it should be on the back edge where you use your thumb or finger to push it into the slot on your camera.

Memory card locked

SD and SDHC 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.

I just bought a new sd 2mb sandisk card but computer won't detect it

Are you using a Memory Card adapter? Or are you using the SD slots that are built into your computer?
Go to the 'Start' menu and choose "My Computer"

The card should be there, if not, then make sure that the little 'lock' button isn't set to lock.

A lot of times when you insert the card, it will switch the position from unlocked to locked.

Good luck

My argus cintar DC5315 will not work with a 2GB SanDisk SD card

Due to the devices age (i have one too, i bought it Christmas 2005) its internal parts are not as strong as newer cameras, and therefore, cannot support as much memory as new cameras. I have an 8gb SD card and the camera does not even turn on with that much space, but with 128MB it works just fine.
