Reasons for SQL Server Database Corruption
- Device Failure: Database files (.mdf/.ndf) stored on the hard disk may get damaged when your disk gets corrupted.

- Damaged network devices: Network issues also responsible for the corrupt database files.

Oversized database files: When your MDF file gets oversized, this will lead to corruption.
Manual Method to Fix SQL Server Database Corruption Issues
Firstly, run the below-mentioned command on the corrupt database:
DBCC CHECKDB (Name_of_corrupt_database)
Once the execution is completed check the index ID.
- If index ID is more than 1, then you can drop it and create it again.
- And if the index ID is either 0 or 1, run DBCC CHECKDB again with the suitable repair options such as-
DBCC CHECK (name_of_corrupt_database, repair_fast)
DBCC CHECK (name_of_corrupt_database, repair_rebuild)
DBCC CHECK (name_of_corrupt_database, repair_allow_data_loss)
