Error: 823 - Torn page - Reposting for Attention

Hi,
I am reposting my problem freshly , previously i posted it
as a part of existing thread. Sorry for Inconvience.
I had a server break down with two harddisks down on RAID
5. Was able to reocover from that situation. When I was
going through the event viewer I found the below error (
the time stamp is after two hours of my server
recovery,when a Maintanence Plan starts). I am not finding
msdb marked suspect and everything seems working normally.
Error: 823, Severity: 24, State: 2
I/O error (torn page) detected during read at offset
0x00000000c42000 in file 'd:\Program Files\Microsoft SQL
Server\MSSQL\data\msdbdata.mdf'.
following the above i found a warning msg
SQL Server Scheduled Job 'DB Backup Job for DB Maintenance

CHECKDB found 0 allocation errors and 2 consistency errors
in database 'msdb'.
repair_allow_data_loss is the minimum repair level for the
errors found by DBCC CHECKDB (msdb ).
DBCC execution completed. If DBCC printed error messages,
contact your system administrator.
I dont have the backup of msdb and when i try to backup
the existing one it gives torn page error.
Is this happend because of Database Maintanence plan which
was scheduled exactly few minutes before at the time of
error msg. I am just using backup option of user databases
and nothing else in that plan . (oR) some data missing coz
of system breakdown
Any help of this will be greatly appreciated.

Well,I think you have onto Maintenance Plan check box 'Attempt to repaire
any minor problems' turned on ,so you need turn off the checkbox.

Do you have a last backup of MSDB database? If you do try to restore it ,
else you need to reser the suspect status.
UPDATE master..sysdatabases SET status = status ^ 256 WHERE name = @.dbname
You must reboot SQL Server prior to accessing this database.

way. From the error it looks as though there was a write error on the disk
prior to the last shutdown of the database.
Here is how books online describes torn pages:
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 backup should be restored, and any transaction
log backups applied, because it is physically inconsistent.

Thanks for the help. I have executed DBCC CHECKDB('msdb',
REPAIR_REBUILD)in single user mode and finding errors with
two tables at SQL output.
DBCC results for 'RTblVersions'.
Server: Msg 8928, Level 16, State 1, Line 1

(1:1569) was not seen in the scan although its parent
(1:1370) and previous (1:1487) refer to it. Check any
previous errors.
There are 2333 rows in 27 pages for object 'RTblVersions'.
--
DBCC results for 'backupmediafamily'.
The repair level on the DBCC statement caused this
repair to be bypassed.
The repair level on the DBCC statement caused this
repair to be bypassed.
The repair level on the DBCC statement caused this
repair to be bypassed.
There are 580 rows in 11 pages for
object 'backupmediafamily'.
CHECKDB found 0 allocation errors and 3 consistency errors
in table 'backupmediafamily' (object ID 2069582411).
I am running only two user databases one is around 1GB and
the other in MB's . I am using Database maintainance
plans - Backup option. I am aware that Information needed
by the SQL Server Agent is stored in the msdb database,
for example, alerts and jobs and tear in msdb wont affect
user databases.
Any help to come out of this situation will be highly
regarded as i dont have msdb backups. Since I am new to
DBA works I would also request you to guide me for any
articles or ur suggestions on what all the databases needs
to be backup on regular basis.
Best Regards

The error that are reported for RTblVersions indicate that there is a
problem with a non-clustered index, which you can safely correct with DBBC
CHECKTABLE('RTblVersions' , REPAIR_ALLOW_DATA_LOSS).
I would also run DBBC CHECKTABLE('backupmediafamily',
REPAIR_ALLOW_DATA_LOSS).
You might possibly lose some data there, but the only information that is in
that table is where (tape or file locations) old backups have been backed up
to, something you can do without. It is only used to present you with a list
of backups to restore in the restore dialog in Enterprise Manager, but you
can still restore the backups if you can rememeber the filename.

Power failure in the middle of writing a page. Hence the name "torn page". If you have HW write

Another option for you could have been to script out the jobs, alerts etc definitions and rebuild
the MSDB database (search KB for how to rebuild). And, of course, do regular backup of all databases
except tempdb, pubs and northwind from now on.
