hi,
I ve got a lot of external HD s and move pics and vids etc
to them
I was on one last night... a folder with say 3000 jpegs in there in about 100 seperate folders

I open the folder with faststone and see about 8o thumbs with a red x on.............. I get them up just to see a dark screen
there were about 20 thumbs that worked ok .....

I moved the folder to docs in my computor... got fast stone up again and the pics are there they all play ok ,,,,

seems like when these jpegs are put on a 2 TB ext HD things arent the same !
