Boot Page Corruption

  • Hi,

    Boot page has been corrupted on the one of database on sql server 2005 server. so the database become un accessable and showing status as recovery pending .

    To do basic analyse i tried to bring the database to the emergency mode to run checkdb command ,but could not. is it possible to bring to the database to emergency mode and then run DBCC checkdb on it ?

    Error message:

    SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0xeb3fb566; actual: 0x5e04b98).

    It occurred during a read of page (1:9) in database ID 12 at offset 0x00000000012000 in file 'D:\SQL\Data\xxxxxxx.mdf'.

    Thanks & Regards,

    Sudhakar A.

  • Hi Sudhakar,

    If boot page is corrupt, you cannot run DBCC CHECKDB or go to EMERGENCY mode.

    You need to restore from a backup.

  • Restore from backup. This is not repairable in any way.
