Msg 3270, Level 0, Sev 16
An internal consistency error occurred. Contact Technical Support for assistance.If you detach the database by using the sp_detach_db stored procedure and then try to attach the database by using the sp_attach_db stored procedure, the following error message may occur:

Server: Msg 5172, Level 16, State 15, Line 1
The header for file ‘d:\pubs.mdf’ is not a valid database file header. The PageAudit property is incorrect.The same error messages may also occur with other models of the DPT RAID controller card.
Resolution
This problem occurs from a particular combination of the firmware version on the DPT controller card and the version of the DPT Performance Enhancing driver, Dptdisk.sys.
