Glad you found them!!
Now the hard part is figuring out how to set the camera back to using card #1 as the default.
Just take out card #2 and put in card #1 and cycle the camera on and off, now you can put card #2 back in and all will be well.
As to deleting images my method has always been to format the card in the camera once I put it back. I usually am working through 4 cards and rotate them. When I download a card it goes in the pile and the bottom one in the pile goes back in the camera and gets formatted. That means I still have the images on a card after download for some time, usually a week or so, until it gets formatted. Just for peace of mind.
Also on the K-1 I have started using card #2 as the primary and card #1 as the extra because card #2 is just a bit easier for my fingers to get out. Card #1 is a little tight, not as bad as some older cameras but card #2 is easier.
