I think I lost Everything!!!!

[T and J Karaoke]

I only use my external hard drive. Some way some how it is on my laptop though. If I go ahead and rebuild my database, where am I going to rebuild it from? I cannot find it on my laptop at all! I am soo frustrated it isn't even funny. I am scared that if I even try to do anything like that it is going to crash. I will be getting me another external hard drive but what is weird is that what is on my external hard drive is fine. I have alot of karaoke that isn't even loaded into hoster yet on there and it is just fine. One of the files is hoster though and that is where I load all the kma files. I usually use my home laptop to transfer files over to my external rather then break out the laptop. Do you still think it would be my external Hard drive even though I have other stuff on it that is fine?
