What is the safest way to power down a TiVo?

    There is a "stand-by" mode and a "restart" function, but there is no "power down" option (at least none I can find in the menus). So just what is the safest way to power down a TiVo?

    Option 1: Put the TiVo into stand-by mode, then yank the power cord out.

    Option 2: Tell the TiVo to "restart", then yank the power cord out at the moment the power seems to cut off

    Option 3: Put all tuners on a non-existent channel so the hard drive stops spinning, then yank the power cord out

    Option 4: To hell with it, just yank the power cord out.

    Anyone have any thoughts on this?

    I haven't found it makes any difference, learned by accident. But if I am doing it on purpose I stop any recordings. But when you think about it, it is always recording the 1/2 hour on each tuner, so why bother?

    It's been debated (in some form) since Series 1 days, and so far nobody has come up with any evidence that Option 4 is not as safe as any of the others. (IMO, option 2 is less safe than the others, but that's just my opinion.)

    I always choose option 2 when I can, but I'm not fanatical about it. I disagree with Crispy about option 2 - this method makes sure that all disk writes have completed and the OS has shut down cleanly.

    I just yank the cord. Never had a problem doing that.

    If there's a way to screw up a TiVo by unplugging the power cord, option 2 seems to me to do the best job of reducing the chance of that happening.

    Which is why that's the way I always do it.



    (If smoke or sparks should suddenly start coming out of a TiVo, I'd change that to "the way I almost always do it." ;) )

    Option 3 is not an option. The hard drive is always spinning no matter what you do.

    Option 5: Use NetFlix App, wait 3 minutes for the TiVo to freeze; pull cord.

    Option 2, all the way, :up:

    Even though I now use WD Red NAS drives in my TiVos, which are advertised as being able to finish pending operations upon sensing a power loss, and I have UPS battery backup power on all things TiVo and network, pulling the power is the only power loss my TiVos ever see.

    We'll never know if the LiveTV buffers get turned off in that moment you menu-reboot, so I used to park my tuners on invalid channel numbers, before I became a WD Red NAS drive fan.

    While TiVos are designed to deal with power losses, at any time, they can't be 100% immune to a bad-timing (just the right moment) power-loss, and data corruption resulting from it, which they might not always be able to recover from, via boot-time drive integrity checks.

    I dare anybody who thinks yanking the cord, without initiating a reboot first, is perfectly safe, to do it repeatedly, allowing the TiVo to fully boot and be ready for use, then keep repeating doing so, making sure to do it under differing operational states.

    I'll still pull power with my tuners active, if I can't initiate a menu reboot first. But, I enjoy not religiously "tuner parking", like I used to...

    Option 1 doesn't really have any benefits (IMO), while Option 4 is just asking for something to go wrong. If you always do Option 4, and it hasn't ever "hurt anything", I feel you should just feel "lucky".

    I'd want a TiVo treated that way, as much as I'd want to buy an overclocked & over-volted CPU (or along the lines of those who compare a re-certified hard drive with a used jock strap).

    To each their own, YMMV, and good luck with however you choose to use/abuse your TiVos. :D

    If you tune all of the tuners to non-existent channels, I think the hard drive does stop turning as there are no active buffers at that point. But I could be wrong.

    Sad, but that was very true, for a very long time, for very many people...

    I haven't had any Netflix lockups on any TiVos for a couple years now. They just reboot, instead of locking up (I guess that's called a "bug fix").

    I'm sure if I say any more (or just leave this as-is), I'll be hearing from those who say there's nothing wrong with TiVo's Netflix implementation(s)...

    I'd rather go without "TiVo-rebooting-during-primetime-while-watching Netflix Anxiety". To each their own, YMMV, etc...

    P.S. I'm not talking about the recent random rebooting TiVos issue that was going around for a few weeks, which didn't require using Netflix to experience.

    Pretty sure you're wrong about this. I used to tune non-existent channels to speed up my TTG transfer to my PC. The HDs are still spinning, they just aren't writing.

    Option 4 should be fine.

    I don't recall anybody here on TCF ever reporting a problem being caused by just pulling the plug.

    Yes, you are "mistaken" (nicer word than "wrong").

    While you can reduce the amount of read/write operations by tuner-parking, the drive in a TiVo NEVER stops spinning, doesn't go into standby, park heads, etc.

    As long as the TiVo, drive, and power supply are operating correctly, the only way it won't be spinning, is if there is no power to the TiVo, or something is wrong with some part of it. This applies to all models/platforms of TiVo ever made.

    Hmm, okay well assuming I am wrong...er, I mean "mistaken", even if the hard drive is technically still spinning when tuner parked, wouldn't it still theoretically be better to pull the plug when there is no read or write activity going on?

    Yes, I thought I pretty much covered that in a prior post here, but I could be wrong/mistaken about that. :D

    A drive always has a better chance of escaping corruption (or suffering less corruption, making it easier for integrity restoration), if it is less busy at the time power is lost (or deliberately removed).

    TiVos still can be quite busy and thrashing the drive while indexing data and performing routine operations, even with the tuners "parked". I respect people who actually think enough to take the time to reduce the drive's load before pulling the power. It has never been proven to hurt to park the tuners. Any pre-Roamio TiVo will gain network speed by parking the tuners. It's even an option built into the KMTTG software to park the tuners (when possible) before starting any transfers (for the network transfer speed increase).

    My notes on the WD Red NAS drives being able to sense a loss of power and complete pending operations may have cluttered up that part. TiVo doesn't use WD Red NAS drives, however. Some of us just choose to use them.

    Option 2 with the emphasis on pulling the plug at the power outlet rather than yanking it out of the back of tivo.

    I've always pulled gently and never yanked anything. ;)

    :D

    Considering many users don't have their boxes on a UPS and that power outages and/or dropouts occur everywhere, sooner or later, can you imagine the chaos that would ensue if Tivo did not design for survival after pulling the plug?

    Clearly, the TiVo software is designed to resist problems, but over the years I have seen too many cases where a power interruption, especially one where the power dropped for a fraction of a second (as might happen if you pull the plug "gently") has corrupted disk drives or even caused the drive to fail electronically. The power supplies in TiVos are not robust.
