My understanding is that if you use the image from one DTiVo on another DTiVo unit, you must execute a Clear and Delete (C&D) command. Is that an absolute truth? Can someone explain what happens that requires running the C&D command? Is running the C&D command still a requirement if you make an image of the donor DTiVo before ever activating/powering on the unit before making the image (using a Virgin image)? Is there any way around running a C&D, but still having transferable images? For instance, does a Weaknees drive require a C&D install from the user, or have they made a drive that does not require a C&D somehow? My second understanding is that running a C&D will erase your logos. Is this statement true? (a corrolary question - do Weaknees upgrade drives have logos?) If it is, is there any way to extract the logo info prior to running the C&D command, and then replacing the info after the command has run? I am going to cross-post this to both the Upgrade and Underground forums (here is the other thread ) - moderators, please delete one of these if you believe the other is more correct.
