Recover MSSQL Server Error 3414


In any instance of database recovery failure at the SQL Server startup, the ERRORLOG or Windows Application Event Log will generally report SQL error 3414 that reads:


"An error occurred during recovery, preventing the database 'mydb' (database ID 13) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support)"


There are a multitude of reasons that are responsible for the error. You need to examine the error preceding this error in the ERRORLOG or Event Log to determine the underlying issue. In a majority of cases, the database is set to 'Suspect' mode and may incur additional errors on further usage. The Error message 926 usually appears on your screen when you try to access a database marked as 'Suspect'.


Taking a particular example, you may encounter recovery failure in case of a checksum error while attempting to read a block in the transaction log file. Every scenario that leads to Error 3414 has the same resolution as described below.




The best and foremost remedy to this problem is to use a good, recent backup for restoring the 'Suspect' database. However, if you do not have a backup, try the following two options:


  • Perform emergency repair using DBCC CHECKDB.
  • Move or copy all recoverable data to a different database.


The first method surely gets your database online and thus, makes it accessible. However, it cannot ensure transactional consistency. It would be rather difficult or absurd to try to find out which transactions have been rolled back or rolled forward, but were not successfully completed. If this method fails, run the following command to set the database in emergency mode:



Now, access the database and try to move all your data to another database.
