Hello, Something just happened that might help someone else. Shortly after getting my B P, one of my flash cards stopped working and refused to accept a reformat, either on the unit or on my computer. Larry suggested that I find another device, such as a camera, and try formatting the card with that device. I didn't find another device that used flash memory. A short time ago, someone from book port suggested formatting the unit without a card and then try formatting the card. It was recommended for another problem. However, I figured that I had nothing to loose. It worked, and now I have 2 working cards . Make it a great one Sharon
