lost files on hard drive

[discdaddy]

Again, this time i need help. All my karaoke songs are on my iomega external hard drive. I did not use it for a week. When i went to pull up a song in search, it said cannot find on hard drive. None of my songs would come up. I can pull them up on my external, but can't pull them up in hoster. Any suggestions? DJdiscdaddy in denver
