Anyone helps me ? I cant attach Database.

When I Attach Database it always rise up Error ( see image). how to do it ? anyone helps me thanks :o :oThe datafile is corrupt, and can not be attached. Perhaps it was not properly detached from the original SQL Server?|||I would restore this from the last good backup, rather than try and attach it. How was it detached in the first place?|||As explained you have to search for a good backup in this case, also review what kind of hardware issues you have on that server.
