This article describes how to use the Eseutil utility to checksum a streaming file.
Exchange 2000 uses a checksum procedure to confirm the data integrity of pages in the database. Errors in checksums normally manifest themselves in ReadVerifyFailure errors.For additional information about the ReadVerifyFailure error, click the article number below to view the article in the Microsoft Knowledge Base:

A utility to manually perform an offline database checksum is available in the Esefile utility that is included on the Exchange Server 5.5 Service Pack 3 (SP3) CD-ROM. You can use Esefile to checksum the MapiRich Exchange 2000 database (Priv*.edb); however, Esefile does not understand the streaming file (Priv*.stm).

248406 Esefile Support Utility for Exchange Server 5.5 and Exchange 2000
If you want to checksum a streaming file, you can use the Eseutil utility, which includes two new switches (/e and /i) that you can use to decide if you want to checksum only the database or the streaming file. By default, you run the utility against Priv*.edb to checksum both files.
NOTE: Before you use Eseutil, use Exchange System Manager to dismount the stores that you want to examine.
The following list describes the new switches for Eseutil:
/e: Use this switch if you do not want to perform a checksum procedure on the database file.
/i: Use this switch if you do not want to perform a checksum procedure on the streaming file.
