No, the disc has not been used since then. Just to complement I informed that the HD has 4tb. There are approximately 5000 film titles, divided into categories by category, example action, adventure, police and others. Each film is approx. 1.8gb in size. The lost folder has 80 (eighty) films, which is equivalent to 200gb. The risk is not to recover the totality lost or corrupt the integrity of the disk unit, that is, losing everything ......
Once again I apologize but it is important to recover what you can ...... without risk. ..ok .... thank you
