The USN journal (or Update Sequence Official Number) is a new feature introduced with NTFS v3. 0. which is responsible for keeping track of all the changes that occur to files, streams, and directories on NTFS volumes. It also records changes in their attributes or security settings. The '$ Log' files is another feature that is added to the NTFS file system. It is basically an NTFS log file that is used to record any meta changes to the NTFS volume. If these files become damaged due to any reason or contains some invalid records, it can cause the NTFS volume corruption. If the damaged volume is the boot volume, then it can make the system unbootable which would further result in the loss of all vital data stored in the system.
