Refreshing DB for hours?

How do I fix this?  I have 995 songs that I am putting onto a 8gb Sandisk microsd card.

I have converted all files to 128bit rate. All ID3 takes and art etc removed completely.  All file names contain only regular characters, no ascii.

However my battery died before it could completely refreshed the DB.  Is there a utility to make the DB?  What other things can be done to resolve this.

I have a 1gb Sansa Express

Thank you!
