Advertisements I'm sorry if this has been covered, but I've searched and can't find any similar previous posts. In the process of trouble-shooting the hook-up a new DVR expander (which still isn't working, presumably due the OEM eSATA cable that I haven't replaced yet), I ran a Kickstart 54 on my Series 3. SMART test gave me a "Fail 7" on the primary drive. Tried Kickstart 57, but to no avail. Called TiVo Support. Tech read through his cookbook and asked if I used a lot of Thumbs-Up or Thumbs-Down ratings. I don't. He had me clear the TiVo ratings and suggestions anyway. Still no help. Meanwhile, I decide to check out my other units with Kickstart 54. The HD-XL seems fine. The old Series 2 DT immediately returns a "Fail ID." TiVo tech told me to repeat Guided Setup. No help. Now here's the kicker. NEITHER of these units has shown the least bit of a problem in actual use. No freeze, no glitch, no nothing. The only "problem" is the result of the SMART test on both disks, which I found only because neither of my HD units would recognize the DVR Expander (again, probably because of the bad OEM cable) and the trouble-shooting guide suggests a KS 54. So, the questions are: Are both of these disks really about to die? Are these fail codes without ANY symptoms really significant? Should I try to offload and replace these units ASAP, or are they likely to last for months/years before I see any symptoms?
