    My hard drive is in the process of slowly dying. I intend to replace it soon. I get freezing, pixelation, occasional reboots, lack of responsiveness to remote commands, etc.

    Many people, including myself, have gotten temporary relief from these symptoms by restarting the TiVo. I was curious as to why and I had a theory. What if it isn't the restarting of the TiVo that alleviates the symptoms, but the clearing out of the cache/buffer? I tested this and have found that with my TiVo at least, if I have problems, I can go to live TV, change the channels (thus clearing the cache), and suddenly my symptoms are gone, for several minutes at least. I suspect that rather than storing the cache/buffer in RAM, that it is stored on the hard drive. Maybe there is some other explanation.

    I know it isn't a cure, but for people in my position, who are trying to get by while waiting to fix the problem, it could be a handy piece of information.

    Interesting theory, and a good example of logical thinking.

    What in the world are you doing here?:D

    So has anyone else ever been told to turn the Tivo over (resting upside down) for a few months each year?
    Can't remember where I read that but it had something to do with lubrication inside the unit needing to be redistributed?

    Stop laughing- I know nothing about what is inside my Tivos!
    But I have an older 540 model with a huge hard drive (from Weaknees) that has always been sluggish and prone to stuttering after using the guide and it does seem to perk up when I turn it over. It has run upside down for probably a year at a time apparently no worse for the wear.

    Kind of a no-brainer really. Two 30-minute buffers for HD channels requires up to 7 GB or more of storage. Since a healthy HDD can easily support the required read/write rates, it would be a stupid (and expensive) design that put those buffers in RAM.

    The only lubrication, and the only moving parts, would be the fan axle and inside the hard drive, so I am at a loss for an explanation of why a change in the relative direction of gravitational influence would make a difference, but would love to know what it could be if it's for real.

    That 540 is probably due for a relubrication of the fan and an examination of the power supply capacitors.
