SYMPTOMS
After you perform a "dirty" restart on an NTFS-formatted computer running Windows 2000, Chkdsk scans the drive and may find some extended file attributes that are corrupt, which it then displays.



CAUSE
This behavior can occur because extended attributes are not protected by NTFS file system transaction logging. Extended file attributes are the data displayed under the summary tab of a file properties dialog box, such items such as Author, Subject, Source, and so on. These attributes can become corrupted by a "dirty" system shutdown.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
Chkdsk may display a screen that looks something like this:

The type of the file system is NTFS.

Volume label is test1.

CHKDSK is verifying files (stage 1 of 3)...

File verification completed.
