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.
