If you can see the pictures, then they are on the card. I've used cards without formatting them, both new and from one camera to another - just experimenting. No problem. Did you insert the SD card into the computer or use a USB cable?
EDIT: Glad you solved your problem.
I didn't format my first card either and it stores the images. I DID, however, format the new CF card I have.
