I think I lost Everything!!!!

[T and J Karaoke]

You are not going to believe this. ok when the drive looked like it lost everything, I was deleting files off of my home computer and updating my books. The version I have on my home computer is 3.321. I decided to see if the worst was yet to come and just hook the external hard drive up to my laptop and have it give me a message such as: F/ cannot find FMA file. Well low and behold all the songs are on there. They are not on my hard drive. I don't know where they are pulling the songs from cause I went into mtu/hoster/songs and they aren't there either but I am not complaining. The only thing I am wondering is where in the heck is it coming from. I wonder. This is definatly an admin issue don't you think? My hard drive didn't crash at all because the other files are on there just fine. I have no viruses. I did a recovery and it didn't find the missing files. Oh lord I am dumb when it comes to this tedious stuff!!!! Does someone have an intelligent answer in plain english!
