Logical consistency-based I/O error I am using SQL Server 2008 R2. My server got accidentally shutdown. After restarting it, I am not able to access my database. I am getting the following error for a few tables:


  SQL Server detected a logical consistency-based I/O error: incorrect
  checksum (expected: 0xd1723da7; actual: 0xab6a6efb). It occurred
  during a read of page (1:69592) in database ID 16 at offset
  0x00000021fb0000 in file 'H:\BACK UP\SQL17052014\databasse.mdf'.
  Additional messages in the SQL Server error log or system event log
  may provide more detail. This is a severe error condition that
  threatens database integrity and must be corrected immediately.
  Complete a full database consistency check (DBCC CHECKDB). This error
  can be caused by many factors; for more information, see SQL Server
  Books Online.


I tried DBCC CHECKDB. It was giving error in one page. I tried to repair that page but not able to do so.

Can any one help me solve this problem?
If indeed it is only one page that is affected, you should be able to perform a page level restore to get the database back. Full details are here:

This does assume that you have a recent full backup of the database.
