Advertisements I've got an unmodified Tivo HD and the 1 TB My DVR Expander, both bought around end of September 09. Both have plenty of ventilation and aren't in anything enclosed. [I've hacked almost all my other Tivos before using mfslive or mfstools before and done it for others too.] The Tivo HD has a single M CableCARD which was provided by Verizon FiOS. I've been using it since day 1. Yesterday, while paused on a show, the unit suddenly rebooted. I went to playback the same show and at some point, the unit hung in the middle of playback. My composite output (yes, not component, I sometimes watch using a video repeating with IR that is composite only) looked normal but hung. Over either HDMI or component (forget which as my bigger TV is connected to Tivo HD via both), the hung picture looked purplish/too bright. I don't think I've ever had a random reboot/hang like this yet on my Tivo HD. I read http://www.weaknees.com/tivo-kickstart-codes.php and http://www.tivocommunity.com/tivo-vb/showthread.php?p=5643823#post5643823. Last night, I tried kickstart 54 and did the S.M.A.R.T. tests, but had to abort a couple hours into it (estimate was ~275 minutes for the secondary [expander] drive). Everything that it got thru in the SMART tests passed (it finished the longer portion of the test for he primary drive). I did kickstart 54 again and ran the overnight tests (took 10+ hours) which passed. Today, I did kickstart 57 and did trigger the intentional GSOD. I left for at least an hour and came back and found it seemingly stuck at "Almost there. Just a few minutes more..." I pulled the plug and tried booting (no kickstarts) but same problem after MANY minutes. I did kickstart 58 which then initiated "Installing a service update. This will take a few minutes" (!?!?) I didn't do 52, as I was going to try that next. Anyway, unit's booting fine now and I'm able to watch live TV again. I'm still using the WD supplied eSATA cable that people say is crap but there's nothing against it to push/knock it loose and the connectors at both ends don't seem loose. Fluke? Possibly dying drive or enclosure? I'm planning on ordering one of the recommended SIIG eSATA cables tonight. I don't think any stores around me carry it. I'm thinking of kickstart 54 and running the SMART tests again tonight and letting them finish.
