    "Hypothesis" not theory. Nothing can be proved so it can't be a theory.

    I have damaged 20-700s by not rebooting properly, but never saw a DVR do what this one did. I think I must have damaged the flash drive that holds the OS. We really should have open minds about this. I've been using externals for a long time and it never dawned on me that I could not treat the 500 as if it were a 20-700. I truly believe that if I had treated the 500 as if it was a brand new model I'd still be using it.

    So, just to check, I shut down two Thermaltakes and pulled the HDDs out of them. I can feel no difference in heat on either the Seagate or the EVDS that I pulled out. Both felt the same on the exposed part as the part that is inside the docking station.

    The only noticeable thing was that the Seagate Cuda runs a lot hotter than the EVDS, but still not hot enough that I felt any discomfort pulling them and touching them.

    Thanks...I think its good to learn all this, and see all the "views" of experience.

    A theory can never be proven, only disproved or accepted. Of course in this case, it would be an expensive risk to attempt to disprove. So perhaps hypothesis is a better word, since most hypotheses prove false :D

    I've been closely monitoring the TT docking stations since I got them. I've even used a heat probe on them and I don't see how the part of the HDD that is in the base of the the TT could get a whole lot hotter than the top. Left to itself, with no outside influence, heat always travels in one direction, towards the cooler parts and if the HDD part in the TT base was getting tremendously hot (in comparison to the rest of the HDD) the heat would quickly migrate to the cooler parts which would soon become as hot as the rest of the HDD. Or almost as hot, allowing for ambient temp to bleed off some of the heat from the exposed part. I have not seen that or felt it or measured it.

    Well, the reason I started Buying and Owning My HR2X DVRs was because after I and several others experienced problems with our eSATA Units we concluded that the eSATA Controller in some units takes Too Long to respond to the DVR so it thinks it doesn't have an External Hard Drive hooked up to the eSATA Port so it assumes it has to Boot up using the Internal Hard Drive and then Proceeds to do so.

    After alot of experimenting one tester finally got his DVR to Recognize his eSATA and he Retrieved All Of His Lost Recordings which were Never Lost but just couldn't be recognized.

    Too Flaky for me so off I went to start Installing 2 TB Hard Drives Internally on my Owned HR2X DVRs. And they are Quieter without having another box to contend with.

    Didn't mean to turn this into a semantics debate but this can't hurt and it's words such as "hypothesis" and "theory" that are incorrectly used as synonyms that always annoy me.

    This is what I accept as the definition of theory:

    Theory - a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses"; "true in fact and theory."

    And this is what I accept as the definition of hypothesis:

    A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation.

    So, as I see it, the progression goes from hypothesis to theory to law, law being a proven theory. And none of them are synonymous. Nor are hypotheses always wrong. And aspects of theories can be proven. Such as Ohm's Law, which falls under the Theory of Electricity. Not the only law under that theory, but the most widely known.

    I agree wholeheartedly with your post. All the HRs that I have put large internals in do work much better than when they have external HDDs. Someday I hope to not have one external drive in my home. That day might come pretty soon. I'm considering purchasing a few 24s for the full price and installing 2TB HDDs in them. That would allow me to do away with all my leased HRs and I would not have the external problems ever again. My 20-700s with large internals are all very dependable and show absolutely no signs of failing (now a couple will undoubtedly fail in the next couple days).

    Since eSata has never been announced as "officially supported", that really should come as no surprise.

    I'm a fan of internal drives as well, but successfully used 2 external eSata units for some time as well in the past.

    Given the choice, I prefer internal HDD, but eSata can work just fine if the right hardware is used.

    Gotta wonder what the "right hardware" is. I've tried a lot of external devices and none have lasted as long as my 20-700s with large internals. Too soon to conclude that the docking stations are the right ones. I know the MX-1s fail for various reasons even tho they are very reliable. But noisy, almost always noisy. With the external devices, it seems to be "always something". If there's something out there that is bulletproof I'd sure like to know what it is.

    Rich -

    In common speech (which we are using on the site) theory and hypothesis are synonyms. Check almost any dictionary or thesaurus and they will be listed as such. In scientific terms, you are correct, they have different meanings.

    Your progression of theory to law is incorrect.
    Laws describe phenomena (usually mathematically). Theories explain phenomena.
    They are two different things.

    I don't want to be rude, but I started this thread for the sole purpose of determining why people were having problems with the EVDS HDDs and not to argue semantics. And I realize that I initiated the argument.

    No offense taken. Like you, I appreciate a good debate. :D

    Anyway, back to topic.

    When I had connection issues in the past, they were with a Seagate FAP750 external attached to a HR20-700. The Seagate enclosure failed and I moved the drive into an Antec MX-1. I then replaced the Seagate drive (which was still working) with a WD10EVDS using the same Antec enclosure and attached it to the HR24-500.

    Since I began using the Antec MX-1, it has never failed to connect the first time. This includes using two different drives inside, and attaching it to two different HRx boxes.

    I'm realize others are having problems, just relating my experiences.

    Maybe the fact that I am using a 1TB drive makes a difference ?

    I bit the Bullet and have been Happy ever since but it cost me but once it's done you don't have to worry about all of the problems associated with eSATA Drives and I was one of the First to go this route but just got Frustrated and wanted a Simpler and Quieter and less conspicuous arrangement.

    You won't be sorry in the Long Run!!!

    I don't think the size of the HDD makes that much difference, but, again, I'm using my 20-700s for a benchmark model. With the new 24s, who can really tell? Give them a year or so and we'll have a better feel for them. I do know that since I started treating my two 24s more gently, I've had no problems with them.

    So, I went from a horrible experience to a good experience and all I changed was the way I reboot both the 500 and the 200. That's what I base my assumption on. Seems simple, but there it is.
