Can't unlock 4gb sd memory card

\015 I have a canon a540 and just put in a new PNY 4GB SD card and it says memory card locked. Camera setup will not allow me to choose FORMAT. How can I fix this?\015

Answers :

There's a tiny slide switch on the side of the card. Slide it to the other position and try again.

\015\012But one thing I've noticed is that you mention that the card is 4GB. As such, it's likely that this card is an SDHC card. There is also a possibility that your A540 camera is not recognizing the card as the SDHC format came out well after the A540 was designed.
\015\012
\015\012If you're still having problems with your 4GB card, recommend trying again with a standard SD card (2GB or less). 2GB standard SD cards are very inexpensive, and can be found on Amazon for about $7 with free shipping.

\015\012And hang onto the 4GB card. It will come in handy again someday.
