My external hard drive that is used to backup everything... just over 300gb of files are missing! I can't find the files, but the space shows as used. They are not hidden... I am not a complete idiot.. but I can't find my 'ish. A few days ago it was all there, I plugged my hard drive into the exchange server at work and created a backup on it (not the first time) and it did, now that is the only thing on there, other than 3 folders that are meaningless..
