The following can be done to reprocess the database:

The first step is to attach the compromised database

  • Create an mdf database of the same size as the old one and stop the server.
  • Copy the broken mdf on the newly created one.
  • Restart the server – the database should be fine.
  • Force the server to retry the restore process
  • Re-mark the suspect

This can be done by executing ѕr_reѕetѕtatuѕ ‘mudbname’ or using urdata master..ѕuѕdatabаѕеѕ SET ѕatuѕ = status ^ 256 where name = ‘mudbname’

Restart the server

If the database is still corrupted, put it in emergency mode, this will happen for torn pages – if you get a rage tear, go straight to

  • update master..sysdatabases et atuѕ = 32768 where name =
  • “mud name”
  • (for v7 it will be updated to mаѕter..ѕuѕdatabaѕеѕѕ set ѕatuѕ = -32768 where name = ‘mydbname’)

The database will now be in emergency mode and allow you to access the data. Now the data will be transferred to another database via dts, bsr or query (I prefer bcp native format).

You will get an error trying to access bad data, but you should be able to parse the rest.

Use Index to access information about broken pages.

To allow the above commands to work, you need to allow updating of system tables

  • Sr_sonfigure ‘allow updates’, 1
  • Resonfigure with override

Don’t forget to return later
