Yes, the key is formatted as vfat, as I'd like to be able to use it 
under Windows as well.

Actually, if I could do something like "chmod -R -x *", that would be 
good enough for me. The problem is, of course, it doesn't work because 
once directories are not executable, chmod can't recursively go into them.

I can't figure out from the chmod man page how to do a chmod -x 
recursively on all files and not on directories. Anybody knows how to do 
that?

Thanks again,
