    No it is not bad sensor. As soon as I unplug external hdd it shows temperature properly. I also tried 3 different ext. hdd's and when plugged in HR21-200 showed 32 degrees. That means that HR21-200 disables internal temp sensor when used with ext hdd. My HR21-700 shows the temp with ext hdd just like yours. It appears that 200 is different in that regard from 700.

    Ah, sorry, I missed that. Never had a 200. Not overly fond of Samsung's products. All my 20/21s are 700s. Wacky world of the 20/21s. You'd think they would all operate the same.

    I'm pretty sure the refurbishing department of D* is an "urban myth". And I have enough stories about purportedly "refurbished" 20s to write a book. Ask yourself this: What MUST be the last step in the "refurbishing" process?


    Me too, and I think the 21-700 is every bit as good, altho it is a lot more sensitive.

    What brand of eSATAs were you trying with the Sammy DVR? I just tried to get an FAP to work with a 21-700 and it still won't. Ever try an FAP on your Sammy?

    From what Ive seen the FAP's wont work with 21's.

    I used to own one but sold it. When I setup my new ext hdd, I went ahead with a WDD this time and a Vantec case, in hopes itll work if I ever have to get a 21.

    I wonder if the external disk you are using reports it's temperature. I also wonder if the temperature you are seeing reported is the temperature of the external disk and not the HR21-700. If you slightly block the air flow on the HR21 does the temperature go up? What about blocking the air flow on the external disk enclosure. Does that cause the temperature being reported to go up?

    Both of my HR21-700s with external disks report 77 degrees. If I shut them down and remove the external disk, the temperature is reported correctly.

    I didn't say it disables the temp sensor, I said it puts the internal disk on standby. I am not a hard disk expert, but I have heard that on the new generation of hard disks the temperature can still be read even in standby while on older disks the temp sensor gets disabled on standby. Maybe the hard disk experts here can verify that.

    Now we have seen posts that indicate temperature sensor being disabled when HR21-700 is used with eSATA, while other posts say the sensor is still enabled but the temperature is much lower than when internal disk is used. So my theory is that HR21-700 (and maybe HR21-200) put the internal disk on standby when eSATA is used (which is the right thing to do). Maybe some earlier manufactured HR21s have older style hard disks, so in those the temperature reading is disabled. But those STBs with newer style hard disks can still read the temperature.

    The Cavalrys will work with the 21s also. Want more info, PM me.

    Glad to see I'm not the only one filled with wonder. These things are enough to...

    The Cavalry 750s that I use do not have a fan. Neither do the FAPs.

    Boy, did we get off topic. One of my 21-700s reports in at 77 degrees. The other 21-700 reads about 118 degrees. And they both have eSATAs hooked up. I have no idea why. And as long as they work correctly...

    If your status screen really says 32F and you do not have the box inside a fridge you may have a bigger issue. The sensor may be broken and the software may use it to activate the fan. If my assumption is correct, you have an interesting issue...

    That is a true statement. Apparently there is a need for the internal drive to keep running even if it is not being used. Seems logical, but with these things you never know. And I have been waiting for a long time to read a post that states positively that either the 20s or the 21s will run without an internal drive (only using an eSATA).

    I don't like to experiment with my 20/21s, but I have checked the temps with the eSATAs connected and the eSATAs disconnected and nothing changes, leading me to believe that the internal temp of the DVR is being displayed or, in the case of the 77 degree readings, ignored.

    Don't forget, I have one 21-700 that reads 77 degrees with or without an eSATA and another 21-700 that reads about 118 degrees with or without the eSATA.

    As far as I know, all the 20/21s do that. Your hypothesis is correct in this case. I think.

    Maybe...

    And as far as I know, that post is the only one that reports a reading that low. Strange...

    All kinds of variables on why/why not the temp works with esata..
    If directv is simply switching sata ports (which I suspect) it would then read temp from external drive.. This then leads to does the external drive as well as the esata chip set support a compatible temp reporting..

    Too many variables for me. As long as they work...

    Was wondering how long it would take you to jump in here. I'm lost.

    make this the 2nd that reports the 32F reading with the eSata.
    i have seen this reading on my HR21-100, HR21-200, and the HR20-100. now once i unplugged the eSata the readings always went back up ranging from 104F-124F.

    I have never had a 21-100 or a 21-200, but I do have two 21-700s and one reads 77 degrees, which if I understand correctly, is sort of a "default" reading and the other reads about 118 degrees. Both are hooked up to eSATAs. I don't know what else to say. I can't comment on the 21-100 or 21-200 and I have never had a 20-100 that worked, so my only source of knowledge is the 21-700. I do know that all five of my 20-700s give the same reading whether they are hooked up to an eSATA or on the internal drive. Makes no difference.

    I see that "Houskamp" has become interested in this thread. He knows more about all this than I do. Perhaps asking him would be the way to go. I'll just sit back and read.

    Always a pleasure to be of use. I will now just read your comments. I don't know what else to say.

    I was actually glad to see that someone else jumped in with that reading. Never know when a Troll will pop up and your post validates his. Thanx.
