The SQL Database error 824 is a logical Input/Output (I/O) error. A logical I/O means that the page is successfully read from the disk. However, there’s an error in the page itself.

Note – If you come across this SQL database error 824, while raising a query or modifying data, the application is returned the error message, and the database connection is dismissed.
For executing I/O operations, Microsoft SQL Server uses Windows API’s, such as ReadFile, WriteFile, ReadFileScatter, and WriteFileGather. After executing these I/O operations, the server checks for errors related to these API calls. If the API calls that have been stated here fail with an Operating System error, then the SQL Server reports error 823. There are circumstances when the ‘Windows API call’ is successful but the data moved by the I/O operation has met with logical consistency issues.
