To manually repair a damaged or corrupted MDF file, you can use the Database Console Command (DBCC CHECKDB). Note that administrator privileges are required to execute the DBCC CHECKDB command. However, this manual method can be time-consuming and technically challenging.

Repairing an MDF in SQL Server manually involves using the built-in DBCC CHECKDB command with repair options. To start, you need to set the database to EMERGENCY mode using ALTER DATABASE [DB_Name] SET EMERGENCY, then run DBCC CHECKDB ([DB_Name]) WITH NO_INFOMSGS, ALL_ERRORMSGS to identify corruption. If errors are found, execute DBCC CHECKDB ([DB_Name], REPAIR_ALLOW_DATA_LOSS) after setting the database to SINGLE_USER mode. However, this method carries significant risks, including potential data loss and downtime. Moreover, it requires technical expertise and might not work effectively in cases of severe corruption or when both MDF and LDF files are damaged.

To overcome these limitations, using a professional tool like the Cigati SQL Database Recovery Tool is a safer and more efficient alternative. This tool is designed to recover both MDF and NDF files without altering the original data integrity. It supports restoring database objects like tables, triggers, functions, and more, even from highly corrupted files. Its user-friendly interface and preview options simplify the process, making it ideal for both novice and experienced users. Overall, while the manual approach is feasible, the Cigati tool offers a more reliable, secure, and hassle-free way to repair SQL Server MDF files.
To fix a corrupt MDF file, first try using DBCC CHECKDB. If the database is accessible, set it to single user mode and run CHECKDB with REPAIR REBUILD. If that does not work, you can try REPAIR ALLOW DATA LOSS but only as a last option since it can remove some data. Always take a backup before attempting repair.
If these options fail or the MDF file cannot be attached at all, a tool like Stellar Repair for MS SQL can help. It scans the corrupt MDF file and recovers all tables, views, and procedures. It also lets you save everything into a new database. I used it when CHECKDB could not fix the issue and got everything back.
