Faulty Ricoh Caplio R6?

I have been using my newly purchased Ricoh Caplio R6 for the Italy trip. It performed well without any hiccups until two days before, when it indicated it failed to record a few of the pictures I took.

When I tried to transfer the photos to my computer later that night, I discovered that a total of 25 pictures were corrupted.

Not knowing the exact of the problem, I reformatted the SD card and the camera has been functioning normally since then. Hopefully, this picture corruption incident is just one-off.
