Hi: I just returned my Toshiba A100 (long story) for a new one which is the identical machine. I am presently restoring from within windows and it is taking two hours (took 25 minutes to image). USB 2.0 external HD. Firstly, I presume since it is the same model and make that this restoration should work? Secondly........two hours.......as compared to 10 minutes to backup? Thanks for listening.
