Memory Card problem....really Need Help!

I am a professional photographer and you need to Format your card every time you use it after removing the images. For example, you put the card in your camera and before taking any pictures you MUST format it. Then shoot away. When you are done download all the pictures to your computer and erase them from the card. Then Format again and repeat the process. This will help insure the longevity of the card and the pictures you take.

Just a note, I buy all the memory cards off of Ebay. They are a fraction of the cost and you can usually get Free Shipping. Just be sure they are not shipping from another country. Only buy from the US or it will take forever. Good Luck!

does the card have a little sliding "lock" on it? If it does perhaps it is locked on accident.

The memory card may not have been a very good one. What brand was it? Just a Canon brand?

SanDisk is a good brand. PNY has also been good for me & is a little cheaper.

You didn't say what kind of card it was (Secure Digital (SD), Compact Flash, etc). All of my stuff uses SD cards. If that's what yours is, notice that SD & SDHC (Secure Digital High Capacity) are different in the way your camera & computer reads them. If you get a new card over 2GB, it will be an SDHC. I found out the hard way that my computer is too old to read an SDHC.. haha But if you have a newer computer, or at least a newer card reader, you should be fine.

It could be a lot of things, not so much the memory card or the camera. We've had this happen on some pics on a card but not all. If you have all the pics off the card that you can get then I would try clearing/deleting everything off the card while it's hooked up to the computer and then reformating once it's empty.

There is also usually a little button/slide that when open allows you to take pics and when closed it is basically locked and you can't do anything. It's possible you slid it to the locked position when downloading if you took it out of the camera. You might try that too.

Once done if it works great, download every few days to prevent it again. Also back up on discs so you don't loose anything should something happen to your computer. That is the downside to the digital age vs. negatives and having to get prints everytime the thing said full. =)

Good luck.

I have a Canon sureshot and mine did the same thing once. Even though I had the card in the camera, it would tell me that there was no memory card. When I re-formatted the card in the camera, it seems like it gave me some kind of error message also.

I took out the card, cleaned it the best I could (mostly by blowing in the little slot, wiping off the metal strips on the card), and changed the batteries in my camera. It seems like I tried to reformat it a second time and it did work then.

I'm not sure if it was my camera or the memory card, but both have worked fine ever since. Just keep trying to turn it on, turn it off, take out the card, put it back in. If it should seem to work, then get the pictures off as soon as you can.

I've used the same camera and memory card with no problems since then.

I recently saw some advice that said not to delete pics from the card. Use the card, download the pics and erase the pics as they download. It has to do with "formatting" the card. I cannot remember what exactly, but I just thought I would mention that for future reference. Unfortunately, it does not sound good for your card - good luck.

You are probably going to have to buy a new memory card. Nice thing is, they have relly come down in price!
