The following steps can be taken to repair a corrupt database:

The first step is to attach the suspect database

  • Create a database with an mdf of the same size as above and stop the server.
  • Copy the corrupt mdf over the newly created one.
  • Restart the server – the database should be suspect.
  • Get the server to retry recovery
  • Reset suspect flag

This can be done by running sp_rеsеtѕtаtus ‘mydbname’ or by updating the master.

restart the server

If the database is still corrupted, set it to emergency mode. This will be the case for torn pages; if you get page broken error go directly to

  • update master..sysdatabases set status = 32768 where name =
  • ‘my name’
  • (for v7, will update to master… set databases state = -32768 where name = ‘mydbname’)

The database should now be in emergency mode and allow you to access the data. The data now needs to be transferred to another database via dts, bcrp or queries (I prefer the native bcp format).

You will get an error when you try to access the corrupted data, but you should be able to access the rest.

Use indexes to access data from damaged pages.

To allow the above commands to work, you will need to allow updates to the system tables.

  • Sр_соnfіgurе ‘allow updates’, 1
  • Reset with override

Remember to set it back later
