Hi there...I am having one Cannon G11 camera...and during the half way of my vietnam trip...It suddenly appear "memory card error" and "memory card locked"...I'd already tried to bring the issue to some of the camera shop in my hometown...and they said the card couln't be read...They couldn't even format it...I am having a lot of valuable photos inside and i do not have any back up of them...I am hoping for the best that I will get a positive reply so that i can get back all my photos...=(

SOURCE: Camera reading memory card error, cannot get it to work. Tried removeing the card and replacing batteries. Checked and it is not locked.

try formatting the card once on a pc and then plug it in your camera....if that does not help either, you'll have to try a different card.

Take no more pics until you've recovered the photos, take the card out of the camera. Here's some freeware photo recovery software that should be what you're looking for. You will need to use ayour card reader with this software.

The reason this occurred is that you likely never formatted the card. The card will work fine in the beginning but eventually will corrupt. AFTER you've recovered the photos, format the card in your camera to prevent this from happening again (dig out that instruction manual to figure out how). Keep in mind formatting will also totally erase your card, so again only do this after you've recovered the photos.

Move the slide switch on the side of the card.

SOURCE: How to format an SD card on a Canon SD600 camera

Could be that you have the wrong memory card.
SD600 will only work with the old SD cards, but the SD780 will take the SDHC cards.
SDHC was intended to give 4gb or more of storage, while the old SD started as 16 mb.  Different cameras have different limits, but it is always best to assume that the practical limit on an SD card is 2mb.  Even if the SD780 will take the SDHC cards, it can be more practical to only carry 2GB SD cards and know that they will fit either camera

Hi,


I highly recommend that you instead consider using a card reader to move the photos or videos to your computer. Card reader's do not require software (although Windows 98 and earlier may require drivers), are very inexpensive, are much faster downloading files from the camera, do not use the camera's batteries during the download, and are much less prone to file corruption of the photos during the download.Really, it would be better for the camera user if one of these was included with the camera instead of the cable and bundled software.You place the camera's card in the reader, plug the reader into the USB port, and your computer sees it as a hard drive. You simply copy/paste or drag/drop your photos onto your hard drive. For this simplicity, most professional photographers utilize card readers exclusively. You'll save yourself a lot of heartache if you convert to using one of these. Also make sure that you get a reader that is clearly stated capable of reading your card, particularly if you use SD-HC, XD, CF, or MS cards.


Thank you!
