Anyone had a failing PS do this, or did the hard drive just go south on its own?
I've got caps and a new hard drive on the way, but I'm curious whether it's worth trying one of the replacement controller boards on eBay; the $40 would be worth it to retrieve the many saved shows I have on it and my functional, but now useless for content retrieval EHD.
(Ideally, if I could resurrect the hard drive, I'd transfer the contents of the S3 to the Roamio that should be arriving on my doorstep tomorrow, put the new hard drive I've ordered into the S3, repair the PS and use it as a backup.)
Probably co-incidental, especially if that was the original 250GB drive, they're starting to drop like flies.
TiVo power supplies that fall victim to "capacitor plague" generally can no longer put out sufficient current, so under load (generally the only safe way to operate a switch-mode power supply, and being switch-mode is why it needs low ESR high temp caps in the first place) output voltage sags.
That can cause all sorts of strange symptoms, but the most likely is either spontaneous reboots (voltage falls too low, the CPU resets), or the drive doesn't get properly spun up (takes more current to start it spinning than to keep it spinning).
I'm not saying it's impossible for the power supply to take out the drive, but but I'd be more inclined to suspect the drive getting old and going bad all on it's own.
Did you mean the drive had been connected to a known good power supply, like a PC's supply?
Was the supply also connected to a PC motherboard at the time (speaking of the need to operate with a proper load)?
The only shows you could possibly copy to a Roamio or other TiVo are the ones (without the anti-copy bit set by your cable company) which you could have been copying to a PC all this time, and that requires the drive be in the TiVo that recorded the shows and the TiVo be working, unless you put a copy of that drive in the TiVo that it can't tell from the original drive.
(Not a job for any Windows programs of which I know)
There's an outside chance, if it's "failing" and not "already failed" of "Xerox"-ing the S3 drive to another drive on a byte by byte basis using a PC, and then sticking that other drive into the S3 after you get the power supply straightened out.
Involves command line Linux stuff and freezing the old drive and keeping it iced down during the copy, which could take a day or two, depending on how small you have to set the "bite" size when "Xerox"-ing.
