SQL Server database or MDF file comprises of valuable and business important information, but different error messages keep indicating that the safety to the data has not yet been foolproof. The series of 8909 errors is one amongst them which say that the database is not with perfect integrity.

Errors tagged with 8909, may be like:

Server: Msg 8909, Level 16, State 1, Line 0 Table Corrupt: Object ID 1, index ID 0, page ID %S_PGID. The PageId in the page header = %S_PGID.

Or

Msg 8909, Level 16, State 1, Line 1
Table error: Object ID 0, index ID -1, partition ID 0, alloc unit ID 281474983198720 (type Unknown), page ID (53:3) contains an incorrect page ID in its page header. The PageId in the page header = (61:3).
Repairing this error requires other errors to be corrected first.

Or

Server: Msg 8905, Level 16, State 1, Line 1
Extent (1:192) in database ID 10 is marked allocated in the GAM, but no SGAM or IAM has allocated it.

Few 8905 errors will also accompany them. These types of errors can arise while attempting to shrink the corrupt tempdb using DBCC SHRINKDATABASE or DBCC SHRINKFILE commands. These have also been seen during the normal operations with the database, while some users also report that while the deadly symptoms, they can’t backup the database and end users are free from any type of problems.

DBCC CHECKDB is the popular and valuable command for having SQL recovery. But unfortunately, this is also incapable to show the efficiency. Though in few cases, this may report success in SQL repair, but the reality is far behind as corruption symptoms remain the same. This limitation has been covered in the latest service pack of SQL Server 2000.
