I went to a family reunion today - some relatives I had not seen in 25 years. Some of the offsprings were hot, hot, hot and I made a lot of pictures on my digital camera. When I insert the memory stick in my PC, it says I hae to format yet when I click on format now...it warns me that info may be erased. I certainly don't want to do that. The pictures show fine on my camera when the stick is in it.
