I tried to convert through Get Info, Quicktime and Graphic Converter, but each time it says it can't understand the format. Now on many of the jpeg files it says that the resource map is bad. I assume this is the problem with a lot of the files i was able to copy off of the offending drive. How do I re-map the resources? By the way, thanks for your help. it's nice to have a community where help is so available. This is one more reason I love my Macs.
