    I recently noticed a high pitched sound in my living room and when my kids tried to turn on my TCD652160 there was nothing... I power cycled it and nothing. Being a sysadmin my first thought was "Oh no, hard drive failure" so I rushed here to get an image. While waiting for a reply to the request I took the old girl apart, coughed through a decade of nasty hairballs and dust mites, and pulled the drive in preparation for a new one...

    On a whim, and because I assumed the drive was already too damaged to salvage I plugged it into my HDD-to-USB bridge and low and behold, no high pitched noise - just the normal sound of drive spin-up (DOH)! So I plugged in the TiVo and hear the sound. It's not coming from the fan so I have to guess it's the power supply. All of the caps look good though.

    Before I order a replacement and in the meantime put a newer drive in, is there any other thing this noise could be coming from? How would I test to ensure it's the power supply?

    Thanks,
    kk

    Power supply issues are common with the old Series 3. Mostly the capacitors need to be replaced.

    Ok... I wasn't ready to try the "fun" of soldering seeing as how I haven't tinkered with it in a decade or two... bought a replacement one on ebay and will try the swap when it get's here. I'm wondering if the high pitched scream could come from something else? I had the hard drive removed upon last test and the fan was spinning fine and to my ear the wound wasn't coming from a fan bearing... nothing else in there left could really make the sound I suppose.

    Well the eBay item I bought on Saturday somehow magically was in the mailbox this morning. That's FAST. I plugged it in and no high pitched noise... WIN!

    So what was the problem? Power supply?

    Yeah I'd say it's definitive because:

    1> I was able to expand to 500G from my original drive while I waited for the part
    2> The high pitched sound still occurred after power up with the HD removed
    3> The new power supply I put in made the sound go away and my (now 70 hour) TiVo is back in business
