There was an I/O error in the past that caused the torn page Torn_page_detection: This recovery option allows SQL Server to detect incomplete I/O operations caused by power failures or other system outages. When set to ON, this option causes a bit to be reversed for each 512-byte sector in an 8-kilobyte (KB) database page when the page is written to disk. If a bit is in the wrong state when the page is later read by SQL Server, the page was written incorrectly; a torn page is detected. Torn pages are usually detected during recovery because any page that was written incorrectly is likely to be read by recovery. Although SQL Server database pages are 8 KB, disks perform I/O operations using a 512-byte sector. Therefore, 16 sectors are written per database page. A torn page can occur if the system fails (for example, due to power failure) between the time the operating system writes the first 512-byte sector to disk and the completion of the 8-KB I/O operation. If the first sector of a database page is successfully written before the failure, the database page on disk will appear as updated, although it may not have succeeded. Note Using battery-backed disk caches can ensure that data is successfully written to disk or not written at all. If a torn page is detected, an I/O error is raised and the connection is killed. If the torn page is detected during recovery, the database is also marked suspect. The database back

P: n/a bbbad_999 I have inherited a poorly administered/maintained database that contains the following error: "I/O error (torn page) detected during read at offset 0x000018ee23e000 in file 'F:\Program Files\ISS\RealSecure SiteProtector\Site Database\Data\RealSecureDB.mdf" I do not have database backups and so therefore cannot restore from them.

I want to move the database to a new platform and somehowrepair the torn page. Is this possible? If you want to get your data out of this damaged database, we can help you. Have a look at www.sql-server-repair.com The error message you got indicates that a data page (8kByte) has not been written completely. So at this page will be some data loss. Regards Thilo Immel The SQL Sevrer Druid www.sql-server-repair.com Jul 20 '05 #2 P: n/a Dan Guzman You might try DBCC CHECKDB, if you haven't already done so. The end of the report will suggest the DBCC CHECKDB repair option needed to correct the problem. As Thilo said, this will likely be REPAIR_ALLOW_DATA_LOSS due to the torn page. See the Books Online for more information. -- Hope this helps. Dan Guzman SQL Server MVP "bbbad_999"
