Lost files fix...
 

A helpful hint from the Macintosh news network's forum.
Go up to The "Go" menu in the finder.
select "Go to Folder..."
type in /Volumes
Look for the name of your Drive's ex-name.
(Like if you renamed the drive you were downloading to from Macintosh HD to Fred, then look for the file named Macintosh HD)
Open that up.
Look around inside there and go through the folders. When you found your files be happy.
