All;
I have 14 errors in one of my tables and I know that all of you would recomend to restore form back-up. But i dont know when this table was corrupted and also loosing even days work is not an option.
Below is what i received from
DBCC CHECKDB ------
I dont mind loosing some data as far as i know what they are.
Any way to know what will be lost??
Or any other way to restore rather than form the backup....

Any related error in sql server log and windows event log? What I'll do in this case is restoring the db on dev server, run dbcc with REPAIR_ALLOW_DATA_LOSS option, then compare the table on those servers.

run dbcc page to see what data you have on that pages
http://blogs.msdn.com/sqlserverstorageengine/archive/2006/06/10/625659.aspx

it looks like you'll only loose the image/text data that link to those pages.
