Hello, My connected USB hard drive to Zidoo X9S got corrupted and stopped working. I'm going to best buy to get a new one and use my backup hard drive to copy all my movies and folders to the new hard drive. The hard drive is exactly the same as the old one. Do I need to clean all the movies in Zidoo and re-scan again or does Zidoo re-scans automatically without making duplicates? I'm trying to avoid making duplicates of folders and movies. Thanks
