Well I got my Seagate HD Ultra ATA/100 ready to install...its just that I need to know what kind options are availble beforehand. The DiscWizard program utility comes with it and instructions to copy system files in order to make the new drive the boot master. However, I don't know if this will copy the complete operating system including the updated service packs...or if it will also make an exact clone image of the older drive including all files and programs. So....is it better to SKIP DiscWizard alltogether and let Acronis do all the work ? I'm also assuming that during the cloning process, the older drive should still be the master, and afterwards it can be switched.
