*RESPONSE NEEDED ASAP* Hard drive not booting and showing up as 6mb large

[Bathtub2007]

So i have a 160gb SATA drive that was working perfectly this morning. I go to turn it on tonight and it gives me NTLDR is missing... so i followed some on this and other forums to see if i could fix it and nothing... nothing what so ever.... i take it to my other comp to see if i could retrieve the data... and all i get is two files in a 6mb large folder that is considered to be my "hard drive" ..... now what the hell am i suppose to do?? i have a lot of school projects on those drives and i can't afford to loose it.....
