Sharepoint Crawler database went to emergency mode

Hi,

My SharePoint Crawl Database went on Suspect mode suddenly & now i need to bring on Online mode.

For solving this issue, i Google on several sites & came across following steps,

Steps:

1. EXEC sp_resetstatus 'DBName';
2. ALTER DATABASE DBName SET EMERGENCY
3. DBCC checkdb('DBName')
4. ALTER DATABASE DBName SET SINGLE_USER WITH ROLLBACK IMMEDIATE
5. DBCC CheckDB ('DBName', REPAIR_ALLOW_DATA_LOSS)
6. ALTER DATABASE DBName SET MULTI_USER
7. DBCC CheckDB ('DBName')

Now the problem is Step 1 & 2 completed successfully, but when i tried step 3 it is throwing me below error,

Msg 945, Level 14, State 2, Line 1

Database 'DBName' cannot be opened due to inaccessible files or insufficient memory or disk space.  See the SQL Server errorlog for details.

I am using the service account which has full rights on the server & through which the SQL Server 2012 was configured.

Current status Database is in Emergency mode & I am stuck over there.

Please help.

Regards,
