i've been going through my sql logs and have noticed that every 10 seconds, a line is being written to a logfile, along the lines of:

2012-11-23 07:50:32.34 spid79      Attempt to fetch logical page (1:30555) in database 24 failed. It belongs to allocation unit 72057594063618048 not to 72057594056540160.


2012-11-23 07:50:34.30 spid66      Error: 824, Severity: 24, State: 2.


2012-11-23 07:50:34.30 spid66      SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0xf651d46b; actual: 0x6290fff5). It occurred during a read of page (1:30196) in database ID 24 at offset 0x0000000ebe8000 in file 'F:\myFolderStructure\RedGateMonitor.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.
