    You can still pause and rewind to the time you pressed pause.

    You can record from the time you press record but the buffer will be empty so you will not get earlier parts of the programme.

    it will stop you from pressing record halfway through a proggramme as there is no recorded buffer to go back on.
    i leave mine set at 30 mins and its worked fine up to now

    It won't stop you from pressing record halfway through. But it will only record from the point that you press record. Which is actually what a lot of people want, and is why people often move up or down channels and back again before pressing record, so they don't end up recording, and then having to fast forward through, half an hour of a programme they have already seen when they come to watch the bit they have recorded.

    I always leave instant rewind turned off. People may disagree, but I think the constant caching to disk all of the time can only be a bad thing. It's not a feature I particularly want to use much, which is why I took this decision.

    It's pointless turning it off to save the HDD, even if you have it disabled, the STB constantly calls upon the HDD to cache the raw transport stream while the box processes the specific channel..

    I had to turn if off otherwise my Thomson (what a surprise) misbehaves..in conjunction with turning anytime off as well otherwise I get the dreaded 'no signal' every day.

    I have IR and Anytime switched off so that my Thomson box isn't flaky most of the time.

    I cannot disagree with you if you don't want to use the feature; however, when many people say this it always sounds a bit like buying a car and not wanting to drive it too often so it lasts longer. It's a disk drive, don't nurse it, write to it, read from it, thrash it, it might fail at some point, but being a disk drive is its job :)

    I'm always gobsmacked at how long fridges can last, cooling all day and night all year! It can't be good for them :)

    Of course, grimsbyseagulls and Orbitalzone have their own valid reasons for turning it off.

    That's nonsense. Nothing is cached to disk when watching live.
    Usage is also not particularly significant when it comes to failure rates. Actually there is evidence that disks that are used less frequently are actually more prone to failure - Google research paper.

    That was a cracking read, pcbbc, thanks. I should point out that this is very much an academic type paper and must be read as such. Readers should note the great number of qualifications (e.g. "in the context of a professionally managed data center (sic.) deployment") and caveats introduced by the authors. So, readers should do what pcbbc has done and introduce its figures and findings as "evidence". Not, as many people will do :rolleyes:, quote the report as absolute conclusive proof. However, I'm convinced ;)

    My post was based on user feedback.

    http://www.avforums.com/forums/sky-hd-sky-3d/1035591-disabling-hdd-using-sky-hd-freeview-box.html

    What I meant to say was the STB uses the HDD all the time regardless of the rewind function..

    I would agree that a time delay exists when pausing live TV with rewind disabled, indicating that the STB has to start buffering MPEG data prior to pausing the picture...(none present with rewind enabled)

    I only remembered the above post because of the novel way in which the SATA was modified :)

    I think it's fair to say the HDD access is reduced, rather than stopped, when disabling the + features though :D
