    If we're talking about extreme heat...sure. But that's not the case here, and the foam is not really any kind of issue.

    The drives in the HR24 series are "green" and give off less heat than most previous HD DVR models they've released.

    The HD DVR (side to side) ventilation is very good in at least 2 of the 3 HR24 models (HR24-100 and HR24-200). I've seen the foam mounting done in some desktop PC's as well - no problem.

    The -500 model has back-exit cooling, which seems to have slightly less outward air flow than the other two.

    Sounds like you just might be some kind of Hard Drive/DVR Expert!!! :D

    Not really....just have seen many of them "naked". :D

    The evolution of how hard drives are mounted has been interesting....starting with the HR20 series, then HR21's, etc. It's obvious the specs have changed and improved over time based on field results (vibration noise being one of the more common past "issues" in some models back in the olden days).

    Yup, as soon as I finish watching all the CSIs on NetFlix, I'm gonna watch Seinfeld from start to finish on NF. A friend of mine gave me a complete set that he had compiled from various channels and had sorted them by date, but the DVDs were of poor quality and I would like to watch them on a better platform.

    Out of all the HRs that I've had, only a couple 20-700s actually had HDD vibration and I've still got one leased 20-700 that occasionally does it. A quick swat calms it down quite nicely. :lol:

    :eek::eek::eek:

    I think I've read a few other folks used that same technique. :D:lol:

    Ah But you did stay at a Holiday Inn Express once, didn't you???

    That's why you know so much about drives and DVRs!!! :)

    As a former hard drive expert, who has also seen some hard drives buck naked, shock/vibration is the #1 killer of hard drives. There are moving parts that have to move with extreme precision, and they don't like it at all when they are budged, especially when powered on.

    Heat is interesting. It is actually good for the hard drive up until around 60 deg. C, but then reliability rapidly drops off after that. So the upper temp. listed in the datasheet is 55 C just to be safe.

    Totally agree on both points.

    In various previous threads...vibration noise from the drives, especially the HR20 units which has very rigid mount setups...ended up being reported with "loud noises". The new techniques used in the HR24 series are a major improvement along those lines.

    Rubber grommets, softer mount hardware, foam, and other things (including newer/better/quieter drives) have virtually silenced those side effects in the new units.

    Well, it works and I'm certainly not gonna give up a functioning HR when a simple swat of the hand solves the problem. :)

    Totally Agree but my DVRs don't move about. They stay put and I never move them so unless you would have one in an RV I wouldn't think that you would have that much Vibration.

    I read somewhere that was called the Rex Ryan technique. :eek2::D:lol:
    Since the vibration can come from loose mounting components, as well as vibration-related noise from the drive itself...DVR's can sit in a location and still "give off vibration noise"....as one specific poster (who will remain nameless) at DBSTalk has indicated perhaps 50 times in the past. That observation was accurate...it's the cure that varies. ;)

    That's external influence, while we're talking about the 'sponge' blocking heat dissipation from the drive. Strictly speaking, the sponge will not protect from excessive external shock/vibrations, it just dampening nose/HDD vibration of the HDD itself. And definitely it will "help" raising HDD internal temp.

    Thanks Rich, I may take you up on that in due time. It's a 24-100. :)

    I Agree 100% With Your Assessment. Well Stated in my Opinion.

    I respectfully disagree, having seen how the internal drives are mounted within all 3 HR24 units.

    The foam will indeed aid the vibration sourced from the hard disk drive and dissipated within the mounting housing and through the HD DVR itself thereafter. If that were not so, there would be little reason to even have the foam, let alone the rubber grommet mounts. The HR24 drives are now so quiet that the foam is virtually irrelevant, as far as hard drive noise alone.

    For that very reason, installing a "different" drive without the foam risks introducing the same vibration issues.

    I think we've gotten to the point of splitting hairs.

    What percentage of all the world's hard drives are protected against vibrations using foam? Very few. And I don't think there are a whole lot of hard drive failures that would have been avoided by using foam. So I think these "risks" from vibration issues are a non-issue, at least in a home-based DVR application. I mean hard drives aren't so fragile that they are susceptible to damage from their own vibrations...

    Maybe the foam gives some minimal protection against failure but I think the main purpose is noise dampening.

    In any case, with the WD 2TB Green drive I think the foam is a bad idea because of the amount of pressure it physically puts against the top of the drive. This cannot be good. If I was using a hard drive that is thinner and doesn't compress the foam so much I'd keep it in there. But with foam or without foam I don't think it matters much at the end of the day.

    I Agree as we have had alot of Noisey DVRs in the Past and a lot of complaints so maybe they went with the Foam to lessen the Noise.

    DO you really disagree on that fact the 'sponge' will NOT protect the HDD from external shocks/shaking [by you for example] ? Plus I highlighted you factual "agree". Huh ? Adding your word "the foam is virtually irrelevant" ...

    "Vibration issue" ? From your [customer] stand point the 'issue' is just a noise, not an issue.
