Canon sd600 wont read 16gb memory card

SOURCE: "Card Locked" error is false!

Remove card from SD600 camera. Locate sliding switch on side of SD card and move from lock to other (unlocked) position. That ought to do it. Compact flash card is another issue.

SD Memory cards have a tiny switch on the edge that marks the memory card as read only and prevents any writes. If you get the message "Card locked!" when you turn the camera on then turn the camera off, eject the SD card. With the card facing you (metal contacts facing away) the switch is on the left hand edge, slide towards the top of the card to make the card read/write again.

Hi there
Save all the pictures to the computer, then format both cards using the menu in the camera, then take a picture and see if it takes them well.


Good luck and thanks for using Fixya!!!!

HC or High Capacity is not compatible with this camera. You have to buy a memory card which says only "SD" and NOT "SDHC". Cards of 2Gb and less are usually "SD". Cards of 8Gb and more are always "SDHC" for technical reasons. Cards of 4Gb can be either, but the SDHC kind are much more common, because they're cheaper and newer.

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
