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 da

page) Discussion in 'General DBA Questions' started by Jon M, Feb 8, 2004. Jon M Member Hi, I'm trying to http://www.sql-server-performance.com/forum/threads/i-o-error-torn-page.4151/ recover a database that became 'SUSPECT'. I tried running the sp_resetstatus, stop and https://bytes.com/topic/sql-server/answers/83155-repair-torn-page restart my SQL Server. Since that didn't work, I detached the database right away and it was not cleanly detached. I tried attaching the database back, but it's giving this below message: Error 823: I/O error (torn page) detected during read at offset 0x000015c4cae000 in file MyMDFHere.MDF Attaching database has dbcc checkdb failed. Any work-around or suggestions will be highly appreciated. My only hope is the tape backup but as much as possible I'd like to try recovering my MDF/LDF if there's any other feasible method.

So I can not help you on this. But there may be more bad news for you since you may still have the underlying problem which caused all this. I had a similar error message (err 823 I/O error) on a single table. After intense research in forums, KB, hotlines etc., I am now convinced that the reason causing this error message is below SQL Server and below the OS layer. My best guess is write cache, disk firmware, OS disk driver or plain hardware (disk or controller) problems. Still researching. I had err823 on a HP ProliantDL380G3 with a pair of 72G 10K rpm disks in Raid1 with a smart array 5i+ controller, battery-backed write cach set to 50%read and50% write. what is your config ? kay27, Feb 12, 2004 #2 ChrisFretwell New Member Jon, I hope you have a backup around. Drop your database, complete, full drop. Run the disk diagnositics and make sure your system is okay. Then recreate your DB from the last clean

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"
