    You are right, of course! I completely missed the max host speed difference on the specs. That sure could explain it!

    One thing I would definitely check are the capacitors on the power supply and replace those that are even slightly bulging.

    dvrstore.com is new to me. What is their reputation? How long have they been in business? My thought would have been DVR_DUDE on eBay:
    http://www.ebay.com/sch/dvr_dude/m.html
    He does have a good rep on this forum. His price for your 1 TB drive is 10+ dollars less than dvrstore.com.

    Given your stated situation and preferences, I think Option A is the best one for you.

    Maybe I missed it earlier in this thread but have you checked signal strength and SNR in DVR Diagnostics? And the suggestion to look for bulging capacitors in your power supply is worth considering.

    Thanks. According to one of the threads here, dvrstore.com is dvr_dude's off-eBay site. On eBay, he does not seem to list a 1TB for the 658000. Also, I wonder if WD would honor the warranty if the drive is bought from him - he sells a 'warranty' for another $26.

    And the bloody capacitors. I thought failed caps would prevent booting. I will open the DVR tonight and check the stuff. Hopefully nothing's bulging or, <gasp>, leaking.

    I did check the signal. It is as it has always been when no problems were present (93-100). SNR 33-34 dB. I'm off the air.

    Capacitor problems in the power supply can, and often do, produce all sorts of strange symptoms that do not at first blush appear to be power supply related.

    But anyone who owns an S2 or S3 and is taking the lid off for anything is foolish not to play the odds and check the power supply, both visually and ideally with a voltmeter as well.

    Unless they have an oscilloscope handy.

    Even if WD honors it, the warranty "clock" starts when he purchases the drive and is usually shorter for drives purchased in bulk as opposed to a retail purchase.

    Plus, that'll be an OEM warranty, as in the party responsible for the warranty is whoever bought a bunch of them wholesale from, in this case, WD, just like if you contact a drive maker about the stock drive in your TiVo they'll tell you to talk to TiVo about it and not them.

    Is a 1 or 2 TB plugin drive for a 658 going to be different than those for a 652?
    You could ask him that.

    Well, I've opened the Tivo. All caps are perfectly flat.
    So I went crazy and ordered a WD20EURS and a USB-SATA adapter. I hope I can get it set up and it fixes the problems. I will report back.

    Would the Western Digital WD AV-GP WD10EURX be the choice for a TCD652160 since the regular HD model can't use the full 2TB drive?

    Both the S3 OLED and the Tivo HD can now fully use the 2TB drive.

    Sorry for quoting myself. I am paranoid and can't stop thinking about future doom :). I.e. what I'll do when the replacement drive also fails down the road.
    If I succeed with this replacement, I plan to buy another 2TB drive for future use soon. Then I could:

    Option 1: Set it up from the original 1TB drive WinMFS truncated backup. I would lose all settings and passes that I'll make in the future. But it is very likely to work.

    Option 2: As unitron suggested earlier, the failing 2TB drive could be then copied in Linux to another 2TB drive. I'm not all that sure about this one. I think you have to be a Stud Hombre Cybermuffin to work in Linux.

    Option 3: Create a new WinMFS truncated backup of the failing 2TB drive and restore it to the next 2TB drive.

    Would Option 3 work if the source drive is an expanded 2TB drive? What if I DON'T expand the 2TB drive I'm setting up now and use it as a 1TB and leave the rest of the space fallow? Would the truncated backup from it work then?

    Season passes are (or can be) stored on the tivo server. Won't those automatically be restored to an updated drive, even if the update was truncated?

    Even if it will work, I don't see the advantage of Option 3 over Option 1. In fact if the 2 TB is actually "failing" you might not get a good backup from it.

    I'm curious about Option 2, also. I know I've seen somewhat detailed instructions for this scattered around the forum. I wonder if you can have problems with such a byte-for-byte copy if the destination drive has a few less bytes total capacity (although both drives are nominally 2 TB)?

    As long as they have the same LBA number, which drives of the same advertised capacity tend to do these days, unlike during the S2 era where the Maxtors were a little "fat", you can use

    dd

    or

    dd_rescue

    (both available on the MFS Live cd v1.4, among other places)

    or

    ddrescue

    (which I'm pretty sure is what's on the jmfs cd, as well as also being available elsewhere)

    and "Xerox" with no problem (although 2TB will take a while) as long as neither drive has any problems.


    As far as I know, WinMFS should be able to mfscopy from one 2TB to another, it just won't be able to expand.

    To get season passes off the Tivo, you have to be willing to loosen your privacy setting. That I am not.

    If I am not mistaken, season passes and settings are on the hard drive and are a part of the WinMFS truncated backup. Only the actual recordings are not.

    Whether you can get a good backup or not depends on how badly the drive is clobbered. A few failed sectors here and there in recordings do not necessarily prevent a successful backup.

    Yes, I wonder too how such a copy handles failed sectors on either drive.

    So what would be the preferred drive for the HD units now then? Is there anything special you have to do for the unit to reconize the full 2TB?

    WD20EURS for as close to $100 including any taxes and shipping as you can get it.

    After putting it through WD's diagnostics long test just to be sure it didn't borked bouncing around in the truck, use WinMFS to copy the original drive to it and then expand.

    Oooopsies!

    Left out that the drive to be copied needs to have the latest version of the TiVo software, 11.0k on it (that's the latest version here in the US).

    And when I say latest I mean of course the one that's been out for quite some time now, and is probably the last time it'll ever be updated.

    Is the WD20EARS ok? I have one sitting in a box on the shelf.
