the sixth field i have already specified as to why i have made it 1 and i am 
glad that the logic applied is proper.It is the fifth field i dont 
understand.What is the dumping for.Some document on dump said it is some 
sort of backup mechanism and i would like to know what is that supposed to 
mean because i am not taking backup and so should all 5th entries in fsab be 
0?or is it like the twin copies of fat maintained by the DOS fs and it 
doesnt matter on the backup that user is supposed to take
