Can anyone give me a little insight about the external hard drive?

    Well, they aren't really "lost" is what he is trying to say... You can still access them if you reboot the receiver without the external drive connected (or turned on)...

    I don't know which works "best", but I can tell you that I could not get the Seagate FreeAgentPro to work... and others have reported the same (even though I have this on my HR20 and have zero problems)...

    Also, I have heard that people are having the same problems with the Western Digital "My Book" external drives...

    I am successfully using the AcomData 1TB pureDrive. I have also heard people claim to have no problems with the Cavalry (sp?) drives...

    You missed the point, which is that PVR drives are never busy enough to ever even get close to the low burst rate of 1.5, meaning it doesn't matter. My speedometer goes to 120, but adjusting it so it reads up to 240 wouldn't really help me much on the 101, especially in rush hour.

    nope, your "missing the point"
    the whole idea of "burst rates" is to free up the proccessor/hardware to do other things while the drive writes the data to the platters..
    And yes the "sustained transfer rate" is what limits it's use for DVRs (Big continuous read/writes)

    Just so all are clear, HR21's work fine with the external drive set to 3GB mode, the HR20's dont like that setting, they prefer 1.5GB mode....at least that has been my personal experience..

    I also have the Cavalry hooked up to my HR-21. Installation steps:
    1. Turn off HR-21
    2. Take Cavalry out of box
    3. Plug in power cord of Cavalry to electric outlet
    4. Connect Cavalry to HR-21 via included eSATA cable that comes with this drive
    5. Turn on HR-21
    6. Set up recordings and enjoy your new 1TB drive which will soon have a lot of HD content!

    I was surprised how easy and fast this was to set up.

    Can't guarantee you on the HR21. I only have HR20-700. Others have posted having problems with HR21.

    The answer is simple. Hardware does fail. You can either buy a duplicate of everything (car might be a tad expensive) and be prepared for a man made item to fail, or just deal with it when it happens. I *love* my TV time, and hate to miss anything -- but when you lose sleep over missing a few episodes of whatever, and a few movies, you need to set your life's priorities a litte better. Don't take this as a flame -- just don't let the little things in life put you on tilt.

    As far as swapping out the internal drive, why bother? Next year they will have 3TB drives and you'll want one. Using the external is easy, brain dead simple, and accomplishes what you want for now. If you own the receiver, then do what you want. If it is leased, do the right thing and you won't have another thing to lose sleep over.

    Thanks for the reply. I completely agree with you that losing 100 hours of recorded TV shows is annoying, but far from the end of the world, and that some people put way too much priority on watching TV. Our reaction to this was -- huh, that's a bummer. And I admit that hardware can fail at any point. But I'm a little more annoyed when it *seems* that I lost all of my shows because of the software update, and not because of a hardware problem, since the drive is still working fine now that we started recording to it again.

    Anyway, I was just curious whether using the external drive increases the chances (probably small, but obviously not zero) of losing everything due to a glitch during software updates. If that's true, what's the point of using a larger external drive when the contents could all disappear? Then it might actually make more sense to live with the smaller internal drive, since (if this is true -- I don't know if it is) the contents would be less likely to spontaneously vaporize. On the other hand, I haven't seen too many other people report losing the contents of their drives recently, so maybe it is some kind of intermittent problem with my drive, or maybe we were just really unlucky.

    For the foreseeable future I don't plan to do anything differently -- we'll keep using the external drive which has mostly been reliable, since the internal doesn't store enough for us... and I'll keep my fingers crossed we don't lose everything again.

    First, I hardly think that is the "whole idea" of burst rates. The idea of faster burst rates is to contribute to a faster overall system, and "freeing up the processor/hardware" is just one small aspect of that. But there STILL would not be any additional "freeing up" going on in a lowly PVR (if any) should you be able to move your HDD's burst rate from 1.5 to 3 G. It just doesn't work that way.

    It might make sense to be concerned about needing a burst rate 500 times higher than the throughput rate if the device were doing lots of heavy lifting, or if it were a conventional PC using virtual memory and paging like crazy, but this is a PVR, not a PC. It is NOT doing ANY heavy lifting, and it is NOT paging VM like Windows Server 2003 at Industrial Light and Magic, or spitting out data like a RAID cluster at Pixar. Its a $169 mass-consumer item at COSTCO. It doesn't need Raptors in it to do its job better any more than your Camry needs a INDY racer engine welded into it for those casual trips to Safeway.

    MY point was that 70mb/s of throughput is about all that a PVR needs, and that burst rates don't buy you anything in this application if the low is 1.5 Gb and the high is 3. Which means that IT DOESN'T REALLY MAKE ANY DIFFERENCE WHICH SETTING YOU USE.

    I would have thought THAT point would be pretty hard to miss.

    Yea... As someone else mentioned... Think of it as an easy way of replacing the drive inside the DVR... If you lose the machine in that instance, you'd lose the content... Same thing...

    I know, I know... It's NOT installed inside... And it's NOT the same thing... But you really can't change the way it works... So you might as well change your perspective... :grin:

    I am on my third Cavalry in two months. First one was flaky - stalls, stutters, IKDs - and then it crashed for good. After slow, you pay to send it back, RMA process, I received number two. It ran two hours and rebooted and the disk activity - the BRIGHT blue LED went out. Started slow RMA process to get disk three but they did pay for shipping. It came yesterday, poorly packed, scratched case, cables rubber-banded together, serial number taped over, and the "warranty is void if removed" seal missing. So now I no longer have a warranty as it was void straight out of the box. I was hoping to at least get a drive that could be sold as "new" on eBay. It works so far but is very noisy. I have requested my fourth RMA.

    I would avoid these drives. I guess most are good but if you get a lemon you are stuck.
