来自msdn的解释：
I/O logical check failure: If a read Windows API call or a write Windows API call for a database file is successful, but specific logical checks on the data are not successful (a torn page, for example), an 823 error is raised. The following error message is an example of an 823 error for an I/O logical check failure: 2003-09-05 16:51:18.90 spid17 Error: 823, Severity: 24, State: 2 2003-09-05 16:51:18.90 spid17 I/O error (torn page) detected during read at offset 0x00000094004000 in file 'F:\SQLData\mydb.MDF'.. To resolve this problem, first run the DBCC CHECKDB statement on the database that is associated with the file in the error message. If the DBCC CHECKDB statement reports errors, correct those errors before you troubleshoot this problem. If the problem persists even after the DBCC CHECKDB errors have been corrected, or if the DBCC CHECKDB statement does not report any errors, review the Microsoft Windows NT system event log for any system errors or disk-related errors. You can also contact your hardware vendor to run any appropriate diagnostics.
