Perhaps change "file" to "disk" as suggested by fat16.h. This part was very confusing.

Also, there was no mentioning in the instructions that the root directory entries may not be exactly located as described in the picture, so perhaps change "78*512" to something like "depending on bpb".

I'm not sure if these choices were intended to make sure that we carefully looked at the code documentations instead of just the instructions, but I think these parts should be adjusted so that other students aren't confused.
