装载数据库时报错：

Question

我在装载数据库时报错：
Msg 3223, Level 20, State 1:
Line 1:
Attempt to read a dump trailer failed; returned error code is 6.
Msg 3219, Level 16, State 1:
Line 1:
The Backup Server encountered an invalid dump trailer page, so SQL Server is not

able to correctly recover database 'train_tj'.  Because of this error, the
database is now suspect.

怎么回事，紧急！
