Software Question

Hi everyone, I am hoping that you can help me. I had a SQL that got destroyed by someone re-initializing the disks on a RAID array and destroying the data. Here's the problem:

11/28/2014 1507 views

I have managed to restore the DB from a very old backup, and I tried replacing the MDF and LDF files with the ones that I recovered from a backup.  The problem is that the new MDF and LDF files were not detached in the copy that I have, so when I start up the SQL server EM shows the DB as Loading/Suspect.  I have tried restoring the database using sp_attach_db, sp_attach_single_file_db.  I get the error The log for database DBName is corrupt' when I use sp_attach_db, and when I use sp_attach_single_file_db I get the error 'Database 'DBName' cannot be opened because some of the files could not be activated'

What can I do?  Can a database be restored from an MDF file that wasn't de-attached first?
