partition copy

Hi, I just got a bigger HDD for my laptop. I need to move the existing windows installation over the new drive. Is there a free utility which will allow me to make a partition copy (NTFS) to a network share, and restore from there? I can not plug both drives at the same time, so I need to copy the old one, and then to install the new one. All this is to make a free space for suse. I taught about running knoppix and dd, but I'm not sure that this will work. Thanks Sunny
