where ‘Error1’ is name of the corrupt MDF database being repaired.

Msg 2510 indicates the specific system table index cannot be recreated, which is also a consistency error.

Screenshot of error message:

Precise Explanation:

In a SQL Server MDF database, there are many system tables used to store the structure and meta data of the database.

When CHECKDB finds there are inconsistencies in the index of one of the system tables, it will report the error message Msg 2510 and try to fix the errors. If it cannot fix the error, then the recovery fails and will lead to more errors, such as Msg 824.

You can use our product DataNumen SQL Recovery to recover the data from the corrupt MDF file and solve this error.
