Re: What is the Usn Journal

If the Indexing service is disabled then it isn't running and can't be responsible for errors in the USN Journal. Here is a description of USN Journal from a Microsoft site:

"The update sequence number (USN) change journal, which provides a persistent log of all changes made to files on the volume. As files, directories, and other NTFS objects are added, deleted, and modified, NTFS enters records into the USN change journal, one for each volume on the computer. Each record indicates the type of change and the object changed. New records are appended to the end of the stream."

"Programs can consult the USN change journal to determine all the modifications made to a set of files. The USN change journal is much more efficient than checking time stamps or registering for file notifications. The USN change journal is enabled and used by the Indexing Service, File Replication Service (FRS), Remote Installation Service (RIS), and Remote Storage."

Note that any other applications (not just Indexing Service, File Replication Service (FRS), Remote Installation Service (RIS), and Remote Storage) can call on or use the USN Journal, so the journal might get corrupted by a flawed application. You can read here for more insight:

Are any errors showing in the Event Viewer log?

I have read some of the KB articles and still I do not know what the
Usn Journal is or its purpose.

Something is corrupting my filesystem which causes CHKDSK to run. The
entry in Event Viewer is "The file system structure on the disk is
corrupt and unusable. Please run the chkdsk utility on the volume ",
which is about as helpful as a bucket under a bull.

When CHKDSK runs it quickly passes over everything but the Usn
Journal, which it says it has repaired. Sometimes I can see an
enumeration of entries being repaired one by one, but most of the time
it just says that it has repaired records in the Usn Journal.

I have never lost Win2K because of this - it always starts as if
nothing happned.
