DescriptionThe file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume <drive letter>
Event InformationCAUSE: This behavior can occur if the NTFS volumes Master File Table (MFT) is corrupted. The short and long file name pairs that are stored in the directory index record and the file names that are stored in the associated File Record Segment (FRS) contain case-sensitive characters that do not match. NTFS supports case-sensitive (POSIX) file names, but Chkdsk does not check file names in case-sensitive mode

RESOLUTION: To resolve this issue, back up the volume that contains the corrupted file(s) and exclude the corrupted file(s) from the backup job. Reformat the volume, and then restore from the backup.
