The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility.

This Error event occurs if the file system structure on the hard disk has been corrupted or damaged by a software or hardware malfunction.

To resolve this problem, back up all databases, logs, and checkpoint files to another drive or to tape, and then run the Chkdsk utility. Or, replace the affected hard disk.

warningWarning:
Chkdsk has been known to delete a database if that database resides on a bad portion of a disk. Therefore, back up all databases, logs, and checkpoint files to another drive or to tape before you run Chkdsk if Microsoft Exchange Server databases, logs, or checkpoint files reside on the drive. After you complete a backup, you can fix the disk by using Chkdsk, or you can replace the disk with new hardware. Then, restore the databases, logs, and checkpoint files from the backup.
importantImportant:
If you do not have a backup of the Exchange databases, logs, or checkpoint files, and you must make a copy of the original hard disk, you may have to try to repair the database after the copy is made.

For more information about how to use Chkdsk, see Chkdsk.

If you are not already doing so, consider running the Exchange tools, which have been created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues and improve mail flow. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
