How to recover corrupted MDF file?

Hi, all,
I have a big problem.
I cannot attach my DB to the server again after detached it.
Error is "...file you've specified is not a valid data file ...".
After checked the system event log, I found "...torn page found at..."
errors before it was detached.
Is there any to recover the database file or recover the data from it?
Thanks a lot.

microsoft.
There are some ways of repairing the file but it assumes
that the database is running and has not been detached.
The only execption to the rule is if its the master
database, then there is a tool to do it.
The best cause would be to restore from the last backup.
