I am seeking an exact answer

I just bought a PNY 8 GB SDHC Card for my camera (Canon PowerShot SD 400), as recommended by a clerk at Best Buy. However, the camera says the card is "locked." I have moved the side tab to every position, but it still gives me the "locked" message. Can anyone help me?

  1. The tab should only have two positions, read only and free. You can try to format the card, look at page 25 here http://gdlp01.c-wss.com/gds/7/0900011247/01/PSSD400IXUS55CUG-EN.pdf

    The tab may be broken, try the card in another camera (newer camera is best due to issue I outlined bellow), or in a PC card reader.

    Another possible issue you may be having is that the camera is from around 2005. There were no cards close to 8 gig back then, the camera may not be able to read the card at all. It came with a 64MB card when new. Try to track down an older card under a gig and try that. Or maybe one of these 2 gig cards http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007962%20600006188&IsNodeId=1&name=Secure%20Digital%20%28SD%29 although those may not work either.

    The largest card offered for that camera from Canon is 512MB, see page 178 of the manual I linked.
  2. that's really kind of you to respond with some advice.
