When faced with the message that file or directory is corrupted or unreadable, start by avoiding the addition of new files on the same storage device. New files may overwrite old data and decrease your chances of recovering your data. This might result from file system corruption, bad sectors, incorrect device removal, power loss or any other issue with the storage device. When the storage device is recognized, it is possible to use recovery software to scan the storage for any recoverable files. Another step that will help is to see whether there is any backup before repairing the issue. Notchox data recovery software is recommended in cases where files or directories are inaccessible due to corruption.
