Hi folks,One of our clients gets the following error when trying to backup a database:quote:________________________________________System.Data.SqlClient.SqlException: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x121db60d; actual: 0x521db60d). It occurred during a read of page (1:1632) in database ID 4 at offset 0x00000000cc0000 in file 'C:\Program Files (x86)\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MSDBData.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.Could not insert a backup or restore history/detail record in the msdb database. This may indicate a problem with the msdb database. The backup/restore operation was still successful.________________________________________I tried to perform checkdb, checkdb repair_rebuild as well as checkdb REPAIR_ALLOW_DATA_LOSS but none of these corrected the issues is the MSDB database. My question is: can I just grab a clean MSDB database from another instance to recover corrupt one or do I really have to uninstall/reinstall SQL Server?
