Symptoms of corrupted (NTFS) file system

If the NTFS file system gets corrupted, you will notice the following typical symptoms as long as you try to access the NTFS partition in Windows File Explorer:

  • The file or directory is corrupted and unreadable.

  • You need to format the disk before you can use it. Do you want to format it now?

  • Hard driver is outdated.

  • This volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted.

Besides that, you might find the partition becomes RAW in Disk Management or shows 0 bytes in its properties. In such cases, you will lose the accessibility to this partition and the data inside it. So you might be searching for effective NTFS file system repair solutions to restore the accessibility.
