MrHatken writes: As many people move to using hard disk drives for online and offline backup one needs to consider possible failure modes. I've heard that if hard disk drives aren't spun up regularly the bearings can lose their lubrication and fail, or the head can stick to the disk when parked.
Are these myths or reality? Is there any confirmed data on how often one needs to spin them up and for how long?
Further though, how difficult would it be for manufacturers to make hard disk drives that would be suitable for long term storage? Particularly, drives that wouldn't be required to be spun up regularly to ensure they'll still function when needed.
It would seem to me that it shouldn't be that hard to do...
