I have a Tivo HD with a 1TB upgraded internal drive (no extended drive) and lifetime subscription. I started having some problems where the unit would freeze and then spontaneously reboot. I decided to run a Kickstart 54 test and here are my results so far: Initial State Pass Short Test Fail 7 Conveyance Test (jumps around between 10-90%) The test has been running now for over 34 hours. How long should it take? Should I clear the test and restart? Why does the percentage complete go to 90% and then reset down to 10% or 20%? What are the recommended next steps? Should I try another diagnostic test?
