Unfortunately, a corrupted MDF file without a backup is a challenging situation. However, there are some methods that may help recover data from a corrupt MDF file. You can try using a third-party tool like SQL Log Rescue or MDF Recovery to scan and potentially recover data from the corrupt file. Additionally, you can also try using the built-in SQL Server utility, SQL Server Data File and Log File Viewer, to examine the file and see if it can recover any data. It's also worth noting that if the corruption is caused by a faulty disk or hardware issue, you may need to replace the affected hardware to prevent further data loss. It's always best to have a backup of your database, but if you don't have one, these methods may be worth trying.
