		Thanks! For you quick reply. I appreciate it. When I read 'I/O error' I guessed that it might be because I was cloning using windows installed in virtual box. So, my hard disk might not be getting enough power through virtual box. 
So, I tried cloning directly through someone else's PC and it clone perfectly.
