                its heck of a pain to restore ,recover or do page level restore allocation pages and you have no other option other then doing a clean restore of your database ..

              some people can do a HEX editing on the file ,but that’s not recommenced

             for more info Check out DAVIS site .. and his 30 day series on Disaster and recovery
