A well-known error is the SQL Server Error 824 which mainly happens as a result of logical consistency and is categorized as a fatal error.

SQL server database 824 error clearly means that the database page has been read with success from disk but the page contains certain issues. Other than this, the messages that may be shown to users may be “fatal error 824 occurred”, “SQL server detected logical consistency-based i/o error”.

Hardware devices or driver software which acts as medium may lead to errors
SQL server logical consistency error can also be caused by file system inconsistency
Damaged database files may be the primary cause for the problem of error 824
File system corruption can also give rise to SQL fatal error 824

SQL server database 824 error can cause heavy damage to the data integrity of the SQL Server database.

EXEC sp_resetstatus ‘db_name’ ; ALTER DATABASE db_name SET EMERGENCY DBCC CHECKDB(‘db_name‘) ALTER DATABASE db_name SET SINGLE_USER Mode With ROLLBACK IMMEDIATE DBCC CHECKDB (‘db_name’, REPAIR_ALLOW_ DATA_LOSS) ALTER DATABASE ‘db_name’ SET MULTI_USER

Issues with Manual Techniques

Highly complex to follow & implement properly for users lacking technical knowledge
