My SQL Server 2008 R2 database was stuck in suspect mode. The database was no longer accessible. I tried restoring it by setting it to ‘EMERGENCY’ mode and then executed the DBCC CHECKDB command with REPAIR_ALLOW_DATA_LOSS option. Executing the query returned SQL error 8921. The complete error message reads:

Msg 8921, level 16, state 1, line 1
“CHECKTABLE terminated. A failure was detected while collecting facts. Possibly temp DB out of space or a system table is inconsistent. Check previous Errors.”

After some research, I found that the error occurs when the tempdb database runs out of space or the system tables are corrupted. The only solution I could find was to restore the database from backup. But, I didn’t have an updated backup available.


I decided to use a professional SQL database repair tool to fix database corruption. That’s when I came across Stellar Repair for MS SQL software.

Step 3: The software displayed two scan mode options: Standard Scan and Advanced Scan. It is recommended that you run the ‘Standard Scan’ for repairing the SQL database file quickly. While the ‘Advanced Scan’ option is for the users who can invest time in thoroughly scanning the corrupted SQL db file. After selecting the scan mode, click OK.

Note: The repair process can take hours to days, depending on your database file’s size.

Step 4: Once the software completes repairing the .MDF file, a ‘Repair Complete’ message box appears.

Step 5: Clicking OK opens a preview window displaying all the repairable database objects. The objects are listed on the left-pane, while the contents of an individual object is displayed on the right-pane.

Step 6: For saving the repairable SQL objects, click Save on the File menu.

Step 7: Select MDF file format for saving the repaired SQL database file, choose the location (default or new) for saving the file, and then enter details to connect to SQL Server. Click OK.

Step 8: When prompted with ‘Save Complete’ message box, click OK.

Executing these steps will repair your SQL database at the specified location.
