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...
