    Has anyone said any different, I have assume nobody is looking for a power adapter for the Roamio plus or pro, but who knows.

    Yes. I should have quoted:

    I don't know what the deal is, either. The Plus and Pro Roamios use (essentially, AFAIK) the same internal power supply as a 4-tuner Premiere does. All signs point to something has changed, or is abnormal, either with the drives, or a batch of power supplies. Others have replaced blown internal Roamio power supplies with those from a 4-tuner Premiere.

    That appropriately was educating me in my ignorance over the Plus and Pro, and my comments above. I wasn't aware--or forgot--that their power supply is built-in (a Roamio standard guy here). So much for my hope for a simple solution, of simply throwing a more powerful external power adapter at the problem as potentially can work for the Roamio standard.

    And I appreciate you trying to help. If others aren't having power issues with Plus HD upgrades, then I am inclined to rule that out as the problem, although I know jack about the subject.

    I am with you that it's very unlikely that both drives are defective, especially since running tests on them shows them to be good. So I'm left with a real puzzle as to why the 1GB original drive works fine and the two 3GB drives (same model as the 1GB) are causing the TiVo OS to have fits.

    The Plus has the same power supply as the Pro, which comes standard with a 3TB drive. I would look at the drives if the original 1TB works.

    Speaking from my logical and ignorant state of mind again, could it possibly be a defect with the power supply, such that it has enough to power a 1TB drive but not a 3TB (kinda, sorta like the possible issue some Roamio standards face)? This assumes that a 3TB drive draws more power. (OK, now I'll shut up and listen and learn.)

    This is one of those times where I'd love to take the time to discuss high-voltage versus low-voltage products/devices/components, and why it's not a good idea to assume the specs on a hard drive are the max, if not specifically labeled as "max".

    Many devices will specify if the max is "continuous" or "peak". That's an important designation, too. I doubt that hard drive companies are saving a ton of money on ink, by not printing that which they used to.

    I'm pretty sure there's an internal spec-sheet for every hard drive, under every conceivable mode of operation, that nearly takes up a full page. I'm pretty sure most of those specifics are only shared with OEM and enterprise customers.

    That workload/duty-cycle presentation telemark shared probably has a cousin presentation on power ratings and requirements.

    I've exceeded my time, and must leave this to sort itself out, or come back to it another time.

    That's a possibility I guess. I mean I've bypassed every other piece of equipment. The only thing I haven't tried is using a different outlet. I don't know enough about electrical stuff to know if that could even make a difference, or how to test the power supply.

    I would clone the 1TB drive that's working to one of the 3TB drives that is not.
    I would also try some outputs that do not use HDCP and a different TV with HDMI.
    I would also try running the system without a TA if possible.

    Depending on what the results of those, it might be clear what's going on, or not.

    That's actually what I was thinking when I first read it. Maybe a sagging power supply?

    Thanks...I have used that number in the past. The hassle is setting up the season passes, channel preferences and losing recorded shows.

    My cable service protects almost all content. I can't even copy shows from one Tivo to another.

    Unless there is a way to clone the drive that I am unaware of, I basically have to spend several hours setting up the new drive in the same way as when the Tivo was originally installed.

    Any suggestions are welcome.

    Thanks,

    I have done all these things, except cloning the drive.

    I agree with you it makes no sense. Would still check the drive for errors and pending errors with the manufacturers software and 3rd party software. (Manufacturer software allows a certain amount of flaws to exist and still passes the drive). Getting a replacement drive from WD might net you a recertified drive that may contain passable flaws. Also might want to check the wdidle3 just to make sure WD decided to change the value that the TiVo may not like.

    I don't believe there are any 2TB expanders on the official Tivo white list, for plug-and-play use.

    There are obviously hackish ways to get a Tivo box to use a larger external but most of them involve rewriting the internal drive at the same time.

    I'm working on one, but it's 3rd on my todo list.

    That seems like a good deal since you get two of them for $9.50.

    Depends on how TiVo updates the list. If they send out a new one that supercedes the old one, a lot of WK customers would be unhappy. If the new list can be merged with the old one, then everybody is happy.

    I meant the model white list, but I think you mean the MFS partition list?

    I never tried it myself, but there's a few posts on here about how official eSata expanders don't work after JMFS expansion so I'm figuring there's some limitation on Tivo's expansion routine.
