Hard Ware Problem No 2

I borrowed the hard drive that contains my film and have taken it home to put the files for my evaluation on it and take it into the college to edit it but my computer will not recognize the hard drive! I have spoken to the college technicians who said it would be because I haven't got the correct drives installed but none of the information help because the files are too big to store on my memory stick and I cannot store them on the hard drive either, I am now three days behind schedule already and far behind the rest of my class I will try and find another hard drive to use but if not I will just have to edit my evaluation from home.
