I have three computers and the card reader was hooked up the the one I was not using.

Sometime ago I had bought a cheap reader ($5.00) from one of those gadget places.

These morning I added my photos to iPhoto with out problems until I placed the card back into the camera which is now frozen (I can't change settings or shoot pictures). The message is "card locked".

This has never happened to me before.

I placed a new card and everything is normal.

What does "card locked" mean?
Will I ever be able to use the card again?
Would it help if I put the defective card into the normal reader which is hooked up to the computer that I am not using but will if necessary?

I don't remember who suggested a burn program instead of Toast but it is great!!!

If it is an SD card, look closely on the side for a little slider switch that will allow you to "lock" or write disable the card.

Thank You,

Yes, the card was a SD. I never had that happen to me before. Now everything is working because I unlocked that very little switch.

Another learning experience.......

You are welcome
