Thanks,Jeff,for offering a possible explanation.What prompted me to post 
was the fact that the example I gave mimicked a more serious problem 
while the solution which corrected the windows disk error was hardly 
what one would think of as being credible;I simply retraced steps that I 
knew worked.
Initially I  got the message from my Windows disk "to insert a disk in 
drive A".After the boot disk produced no solution,I ran fdisk,I 
believe,and it was there that I was informed that,"No fat file was 
present".Because I was dealing with removable drives,I knew that the 
windows drive was not involved in anything major;data would be there 
still.Having the two drives allows me to have two ways to access 
information on the net,a plus for me,while helping to separate issues 
that involve either disk.I'm a true beginner at things Linux and computers.

I'll read up on dd and issues posted in reference and see what I can learn.
