Everyone i have seen many threads on this & other forums as well about 1:1 copy but still not understood it.
How do i make 1:1 copy.Do i have to use external cd/dvd drive to do that?
What i mean is one disc in laptop/computer drive,other is externally connected as it call destination drive,while making backup copy. Am i right?
please explain it properly iam any thoughts would be appreciated.
thanks in advance.
