    We did talk about this to some extent. Thing is, I'm trying to run the SSDs as I would run an HDD. I want to see when the problems start, if they start. I have a pretty good idea how long it takes for an HDD to get a bit wonky. I have no idea what's gonna happen with the SSDs.

    Agreed Rich, it was getting heat from the motherboard and power supply inside of the box, but not hot enough to run the fan all the time. The fan was not running when I took the cover off. It’s much better now in the dock.

    The other good news today is that my wife did not notice any freezing/pixelating during the day. She had several different channels on over several hours. That’s a good thing.

    The thing to look for if those video issues pop up are: Can you replicate them? If you can it's probably the broadcast, not the box. Do you see those issues on one channel and no others? Same answer, probably the broadcast. Do you see the issues on all channels and can't replicate most of them? Now you have a problem that probably points to the drive, HDD or SSD, assuming all other components and connections are functioning properly.

    The SSDs we're using have a heat range of 0-70 degrees C.

    There is so much secrete sauce in SSD controllers and chip sets that one can't make a generalization with any confidence. Idle time, if effective for your specific model and firmware version, should be in terms of minutes not hours. You could run some specific laboratory controlled test.... but then may find that the SSDs you buy next month have revised firmware and operate differently :).

    Rebooting your DVR provides a few minutes where no recording activity is taking place, while it is busy acquiring signal, doing the initial guide download etc. before it reaches the point where you can begin watching. There's also the test menu, if some of those interrupt the recording activity.

    Of course Rich has been running SSDs in his HR24s for months on end without any problems, so what write activity there is may be slow enough to leave plenty of time for housekeeping. It is only writing a couple MB per second, after all, which is less than 1% what the SSD is capable of, so it isn't exactly working hard.

    A couple months ago I had a 24-500 go bad and sent it in for a refurb. Got another 24-500. This one makes me think they don't do anything regarding refurbishment. It was slow and cranky when I activated it (this is the 24 that ATT couldn't activate for almost a week because they DIDN'T KNOW HOW TO DO ACTIVATE IT) so I put another SSD on it in a dock. Now it works as the others do but it keeps crashing. Just happened again yesterday.

    Here's why I'm writing all this: Each time the 24 has crashed I've either pulled the cord or hit the Red Button to get it to boot up. I haven't touched the dock. Each time it has booted up properly with the SSD. I don't think the same thing would happen if I tried that with an HDD in the dock. Thing is, I don't remember if I ever tried this with an HR with an HDD in a dock. Not sure if the HDD/dock would connect to the HR as the SSD/dock did. Does anyone remember having done this?

    I do that almost weekly Rich, and it works the same. On my owned HR54, I have a 6TB drive inside the DVR, and a 6TB drive in the dock. I have the separate drives for recording certain programs. Leaving the dock ‘on’, and rebooting the DVR will load the HD from the dock, and not the internal HD. Does that answer your question?

    I have a slightly different situation. The 24-500 keeps shutting down or crashing. It becomes unresponsive and I have to use the Red Button or pull the plug to get it to boot up. But I can't see why that would be any different than what you're doing. I just don't remember ever doing this. I always shut both the dock and HR down and started them in the proper sequence. It seemed so odd I thought about taking an HDD and putting it in that dock just to see what would happen. You answered my question, thanx.

    Not sure if it applies to DTV boxes but I have had hard drives go bad in a computer and the computer will not boot as long as that bad hard drive is in the computer. Not even from another drive. You might try removing the internal hard drive or unplugging the cables to it and see if the problem disappears.

    Rich- do you have any 24-500 backup power supplies? I have a stock of parts I keep for my owned receivers. If you do, try swapping it and see if you’re problem persists.

    I keep extra parts, with the exception of the motherboard (RID sensitive) so I can fix and save my recordings, instead of getting a full replacement in the event it’s just a fan/bezel/power supply issue.

    Easier to get it replaced. Nothing on it I care about. My 44 did the same thing for quite awhile. Just crashed for no reason. I waited it out and after a couple NRs the problem went away. Might be the power supply on the 24-500, might just be a software problem. I'll wait for the next NR and if that doesn't fix it I'll get it replaced. I'm not using it for anything at the moment and I don't feel like calling for a replacement, just the thought of making that call disturbs me. Thanx for the suggestion.

    What I've seen using HDDs with HRs is the HDDs degrade over time. Just like most mechanical devices. When the degradation gets to the point where you start seeing a lot video and audio problems the HDDs keep running. And they'll keep running for quite some time and the problems will get worse. Running the tests on the HRs won't tell you if the HDD is degraded. You can see the difference in a new HDD and a degraded HDD by simply taking the degraded HDD out and inserting the new HDD. I've replaced a lot of HDDs that were still working because the HRs got so slow and wonky I had to do something. If you have an HR that is slow and difficult to use replacing the drive usually works. That's not gonna fix problems that are caused by the broadcast tho. If you can reproduce those audio and video problems it's probably not an HDD problem or a box problem. Assuming you don't have these problems on other HRs and all connections and devices are working properly.

    For those leaving HDD's 'floating' on the cables, it will cause minor but noticeable performance degradation vs. hard-mounting them to the case or an enclosure.

    Among other things, I used to run an OS performance org at a very large Redmond-based software company, and was comparing IO performance of various hard drives. I was getting variances in seek times between identical drive models that came from the same batch.

    Turns out hard mounting them (vs. hanging on cables) sped up seek times 100% of the time. My theory (confirmed by the drive vendor) was that the (very high g) acceleration of the disk head during seek, was causing the free-floating drive to torque the opposite direction slightly, enough to impact the travel and settle time of the head.

    Its worse than that, the vibrations induced in the head assembly from simply screaming a few feet from a hard drive will cause errors during reading or writing!

    That 24-500 is still running. It appears to be doing the same thing my 44 did a couple years ago, runs for quite some time and then crashes and is unresponsive. I really think this is a software issue, not the power supply. It's been running since before we had this discussion. I can't believe it's the power supply that's at fault. Every time I've had a power supply go bad I saw no blue lights on the front panel. And the HR was unresponsive, of course. No power, it's not gonna do anything. And I could never get one to boot up, this is a different experience. The 24-500 boots right up.

    Okay. I currently have 4 HR24-500’s and mine are not crashing like yours, so I didn’t think it would be a software issue. That led me to think maybe a diode or capacitor or something may be failing on your IRD power supply, perhaps working fine for awhile, but then failing and reducing voltage to the motherboard causing a crash. It was just a thought.

    How long after a reset does it work before crashing again?

    Weeks. That's what makes me think an update screwed it up. Screwed up my 24-500, I mean. Doesn't mean every 24-500 is gonna be screwed up. As I said it's acting just the way my 44 did a couple years ago. Don't recall anybody else having a similar problem at that time with their 44s either.

    If an update screwed it up have you tried forcing it to do the update again?

    No. The 24-500 has nothing of value on it, don't really need it. I can wait for the next NR.

    I don’t see a lot of new NR’s on the horizon for the 24 coming Rich, unless they start removing more features, which has been the trend.

    The last update was last November, and nothing else has been put out in the testing world for a new NR that I have seen.

    It may be worth it to do a 02468 on the next reboot......
