7D Mk 2 lost images from c/f card in camera.
Took my new 7D Mk 2 out yesterday evening for bird photography and took about 180 frames. When I returned home I was reviewing the images in camera and deleting obvious non starters when the red light at the bottom right of camera back beside the lock button lit up permanently and a message came up on the screen "Unable to access No 1 card, Replace card or format card". I was unable to do anything with the camera with this card in. I removed it and replaced with a new formatted card and everything now seems OK. The images on the card I removed from the camera have gone, not one remains. I have tried recovery with Sandisk Rescue Pro but they are not there, the camera removed the files forever. I am leaving for Portugal tomorrow so will not be able to take the camera to the store from which I purchased it. Has this happened to anyone else and if so did it reoccurre?
