When you say "clear the format" what do you mean...what are you doing exactly? winMFS formats the drive automatically so I'm wondering what you are doing and if it's affecting your ability to make a copy. Per the others, copying via USB can take quite a while and IIRC you can ignore the time counter as it can change often and not be accurate. If you watch your system's activity (under Task Manager or better yet Process Explorer) and winMFS is showing activity all should go well. It is possible that your new drive has some bad sectors and the copy process is being stopped at that point. Did you happen to run a drive diagnostic like WD's Lifeguard? If you still have trouble with it you might want to give that a try. Best of luck and let us know how it goes.
