    You need to replace that capacitor before trying to diagnose anything else, although you can hook the drive up to a PC and run the manufacturer's diagnostic long test on it while you're fixing the power supply.

    Your drive probably crashed because it wasn't getting the power it's supposed to or the part of the motherboard that talks to the drive wasn't getting the power it needs to function properly.

    Sounds like a problem communicating with the hard drive.

    Which is not always the fault of the hard drive.

    Do you have, or have access to, a voltmeter and do you have any experience using one?

    In the meantime hook the Hitachi to a PC and run the manufacturer's diagnostic long test.

    It's probably available on the Ultimate Boot CD, and it's good to have a copy of that handy anyway.

    Well, tried Hitachi test from download - it couldn't see the drive although Windows disk manager could. So created an iso image on CD, and tried to load. Failed with two different burners - seems that the Hitachi iso test will not handle 64 bit OS. So got out the two old Tivo disks from the HDs, and have exactly the same problem so I think all the drives are fine. Guess I could pull the drive and put it in my other HD to see if it works.

    I'm not a great hand at soldering, and since I can see nothing wrong with any caps, would have to start down the list of replacing a bunch. At $99 for a new power supply, plus shipping, etc. seems to be a good portion of the cost of a new Tivo. Its only $149 for an HD replacement from Tivo, which is the same price as a new Tivo Premiere - guess I'll have to switch the innards from the other HD so I can keep the lifetime if they won't move it from one to the other.

    Wish I could be surer about cap problem and replacing them.

    Look for a local electronics shop to replace the caps. Since they are cheap, just have them replace all of them at the same time.

    Tivo sales offering HD replacement at $79.99 - cheaper than a new power supply and probably not that much more than getting a bunch of caps replaced. In the end, am ordering a new Premier at $149.99 and will put my 1TB drive in it - or maybe use as extended drive. Both probably have same warranty effect, but not sure if there are still the old problems with extended drives.

    Thanks to all for the help.

    What do you mean by extended drives?

    Should have said expanded - I seem to remember when I upgraded my HDs to 1TB that there was also a way to add 1TB expander from a non-Tivo source. Its been awhile since I went through all the strings. There used to be a lot of problems with reboots because of expanders - I got rid of mine when I went to 1TB internal.

    You do know that in order to use that 1TB drive in the Premiere, your going to have to re do the software, right?

    Looks like Im joining the bad cap club... My TiVo S3 (bought first week of availability) rebooted this afternoon and is now stuck in a reboot loop. Its not the HDD... I have a backup drive that I update periodically or such occasions and the reboot loop persists with either drive. I see 3 bulging caps on the power supply. A pair of 2200uF 6.3v and a single 2200uF 25v. Ive ordered replacements and hopefully that will get me back up and running. Fingers crossed.

    I wish I'd known sooner, there's a guy in Raleigh could have fixed you up with the caps at a good price, or even done the repair if you wanted.

    (that would have cost more than just the caps, obviously)

    Same problem original S3 stuck in reboot loop. I had upgraded to 1 TB internal and 1 TB external drive. Put original drive back. Same. A couple of caps look like they are bulging. Will see how handy I am with a soldering iron when the parts arrive.

    A soldering gun would be even better--higher wattage, more heat.

    One side of the caps, the negative lead, is soldered to the ground plane and it's big and dissapates heat fairly well.

    3 caps were bulging. Bought the same 11 caps from another post and replaced. Worked, S3 is back in action. Imagine that. Thanks guys.

    Is is absolutely necessary to replace caps with the exact same voltage as specified on the cap? I picked up two 1000uf 35v caps to replace two bulging and split 1000uf 10v caps in my TCD652160 PS. Everywhere I looked online said that higher voltage is ok and safer. Maybe I just did a poor soldering job.
