All of a sudden (meaning as far as I know nothing has changed) my CD Rom's (I have two, one internal and one external) have started to read the CD's incorrectly. On the cd is a file "this_is_a_file.jpg" lets say. No matter which CD Rom I try to read it from the file becomes "this/is/a/file.jpg" as thus my computer can't read it because of the "/" characters. I can read it properly in a different computer it's just this one that reads the files wrong. Any ideas what's going on?????
