How can I restore corrupt .edb?

I have an exchange server with a .edb that is in a dirty shutdown state. I have 2 storage groups. The second storage group will not mount due to dirty shutdown. That database is on e: drive, the transaction logs are in C:\Program Files\Microsoft\Exchange Server\Mailbox\Second Storage Group I tried to run eseutil /mh e:\exdb2 but I get an error saying that the file is locked.
What is the exact command I need to run to repair the .edb?
