MSSQL 2012 logs DB corrupted

I have a server that crashed and i'm trying to move MSSQL database files onto another server. They have all reattached except for one. I'm getting the following error:

Microsoft SQL-DMO (ODBC SQLState: HY000)

Error 9004: An error occurred while processing the log for database....

I have NO backups & obviously need to mount this.

Any ideas?
