I thought I recognized the "3 years" as something I wrote, so I looked up the HDD Info help file and it's a little different than a 3 on/off per day = 3-year life span:
"Info on HDD Longevity
Drive mfgrs rate their longevity in "contact start/stop cycles" not spin or working time. A start/stop cycle is defined here as a power-on/power-off cycle... 50,000 for our drives. So, if you power this DVDR up/down three times a day, you might think you'd get 45 YEARS out of the HDD. But, in the REAL world, experts say 3-5 years is a good lifespan for a modern HDD, as described here. Those just happen to be the std warranty period for HDDs... as of Jan 1 2009, Seagate lowered their std warranty period from 5 years to 3 years for our 3575/3576 HDD, and the same as the Hitachi 2160 HDD."
But you're right about turning these DVDRs on/off... those are the "events" the mfgrs use for their longevity estimate of 50,000 cycles.
However, I've got a 3575 test unit that I've cycled on/off MANY times and it's still going strong. I read the mfgrs words but I just don't know how we can use that info to influence our preferred patterns of use... i.e., I wouldn't let any stats get in the way of enjoying these machines.. but then, I've got 4 of them so maybe I'm not the best spokesman for unbridled turn-ons!?

I think you mentioned your 2160 turning on when you turned the TV on possibly cuz of the HDMI Control the "A" version has? I thought that control was only supposed to turn a compatible TV on when you turned the DVDR on, not vice versa. If the reverse is also happening, I don't think that feature is worth all that much and I'd turn it off.
On another subject, Auto Clock... setting Auto Clock to a good network channel, like FOX, using the MANUAL menu confines the time search to only that channel so it can't find a rogue signal (unless FOX goes "rogue," but Sarah isn't running it... yet), BUT it also increases power-backup time from at least 2 minutes to several DAYS... even if the channel you use doesn't provide a time signal! (Just don't use a local/community station... mine froze my unit so no buttons worked!
)ALL my units survived with everything during a 12-hour complete area blackout, incl. the volatile time/timer memory, and several people have reported power backup for even longer... it seems these units gain "strength" as time goes by!
