Scan eorror - WD My Book -Essential 1TB

Was getting message to scan My Book for errors, said no for about 3 weeks, but was still able to open and view folders. Yesterday I decided to just run the scan and fix, now all of the files are in foreign language, files will not open and only shows 14MB of free space. Any suggestions?  All HELP is welcomed!


Check the drive for malware or viruses

copy the files to a different place if no virus found
