Hi, This may be a dumb question, but I need to verify something before I start. I currently have a two-drive system. The C: drive is 40GB and the D: drive is 20GB. I plan to replace the 20GB with an 80GB. Here's the question I ask because I'm not really conversant with registry-speak: will images created with the 20GB work when it is replaced with the 80GB, or will the system burp? TIA. BTW, without sounding like an advertisement, I only wish I had purchased this product earlier than I did. I would not be in the situation I am in now if I had (sigh). I will never install or upgrade hardware or software again without first making an image. To coin a phrase, "Don't leave home without it."
