You can easily create a backup image and restore it to another drive. There are lots of tutorials on making copies of a Tivo drive so you may want to look around, starting with Hinsdale's How To and also the Weaknees website for their online tutorial. The hacks are retained when creating a backup image and are transferred to the new drive. If the unit is hacked then the better option is to install and run the 51killer.tcl script instead of performing a Clear & Delete Everything as this will retain any season passes or other settings you have set up on the original drive.
