    You could do that but the cable card would un-pair itself.

    Yeah, you would have to at least re-pair the first time. What might work, assuming the drives were identical is to set one up, including CableCARD pairing then copy the whole thing to the new drive before you install it.

    Another interesting experiment would be to set up a stock drive on a Basic or Plus, copy the drive to a larger drive, install the new drive and see what happens.

    Note: I am not asking nor even encouraging anyone to try either of these experiments since I am definitely not in the position to test myself and am not likely to be so positioned in the foreseeable future.

    Don't forget that most HD are measured in Tebibytes (TiB - base10 e.g. 4x10^12) not Terabytes (TB - base2 e.g. 4*1024^4). So the "4TB" HD is less than 2^32 1k blocks.

    I suspect we're able to do this as someone figured out that it's much cheaper to buy unformated HDs and have the Tivo format it (rather than pay the HD manufacturer or someone internally to do it).

    If I took my 2TB EURS out of my Premiere and slapped it in a Roamio, what are the chances the Roamio would configure it properly AND retain the recordings?

    Slim and none, right? And Slim probably just left town.

    Zero. The recordings are encrypted to the hardware they are recorded on. There is no way they would work in the new box.

    You could not do that between the exact same models of TiVo, remember the C&D all to change drives.

    Zilch, nada, bupkis. Why would you even ask? It's never been possible to do this even with like model TiVos and in this case, it is unlikely that that the drive formats are even similar.

    I would ask because I've only been using Tivo for about 8 months so I'm still a relative noob at this stuff. I was 98% sure of the answer but that nagging 2% prompted the question.

    When the drive specs are specifying "streams" supported, they are specifying streams using the ATA streaming command extensions (AV) command set. This spec includes how many streams are supported both writing and reading concurrently.

    If TiVo has stuck to tradition, and still reads/writes AV data as any old data, this spec still means NOTHING, when used in TiVo context. If TiVo has finally upped their game and started using the extensions (the part that makes an AV drive operate as an AV drive), then it could make a difference (and possibly even make using non-AV rated drives impossible).

    I haven't seen anybody test a non-AV drive, yet, or they didn't say they did. Until that specific test is done, and made clear that is the test they have tried, and given it some hardcore usage, we just don't know yet.

    As I'm sure you know, tests need to be replicated, before the results can start to be assumed as proof-positive. We've seen multiple upgrades with no issues, up to 3TB, so far, using AV drives. Unless I'm mistaken, we haven't seen a single non-AV drive upgrade yet, let alone any replication. Until we do, it's unknown if non-AV drives work at all, or will work under maximum load, reliably.

    If they did make the switch to true AV streaming, but left the door open to still use a non-AV drive, I'd expect it to be a "fallback" means. It would take some time to let the drive fill, then fragment, to see if performance/reliability gets affected...

    I'd be shocked if they used anything but standard I/O, but I was shocked at how many improvements the Roamio included. I think it's still anyone's guess at this point.

    I thought one or two people posted that they put in a non AV 2TB drive?

    If you could find the posts and post the links, I'll be happy to concede that I was wrong. I thought I was paying close enough attention that I would spot them, since I've been primarily focusing on this thread and watching closely for such a thing...

    It could have been a different thread. The last week has been crazy reading this forum with posts coming at a very fast pace. I don't even think I've ever seen so many posts in such a short period of time on this forum. It's been hard to keep up.

    That's VERY true. No argument from me, at all. I have NEVER seen such a fragmented subject matter, as to the extremes the Roamio has created here (the users/speculators/spectators, not the Roamio).

    Received my 3TB WD AV drive, and everything was pretty straight forward. Put the drive in, and Roamio will automatically get the setup going. I lost my premium channels (HBO HD) from my cablecard (but regular channles were still working), so I had to call Comcast to repair the card. Otherwise everything went as expected. Very easy process.

    How many HD hours with the 3TB?

    Is it really this easy? Plop in a new drive and turn it on?

    From what I have been reading - yes. It is that easy. Almost too good to be true ;)
