(those with gas heating) Melb 18Jul 20, 2011 9:22 am btherl It's not a joke.. a typical hard drive is designed to tolerate a temperature increase of 20 degrees over an hour. You'll easily exceed that if you start it too cold, and doing it regularly is a sure way to lower the life of your hard drive. Think about how much the internals of the hard drive expand and contract as the temperature changes. The drive will do its best to compensate but it can only handle slow temperature change. Letting it get too hot is bad too, but I've seen more problems due to temperature change than due to high operating temperature in Melbourne's climate. What cmhamilton said and just to add after over 26 years in the field including fixing the darn things to component level (no board swapping), working with 19 inch hard drives where you have to replace the heads!! and working in organisations with 3 to >100 000 machines I simply cannot agree with your advice. The vast majority of HDD failures are in units that were running at the time and had been doing so for extended periods. Cheap servers are notorious for their high HDD failure rates because of the cheaper drives that are used - because they are always running, servers need very high quality drives and RAID together with regular backup is used as the fail safe. Ask any good techie about how many HDDs they go thru with their always on equipment. Frankly don't RELY on google to find all the answers - there is a LOT of wrong or misleading info out there. Theory and practice are not the same thing. Re: how big is your elec bill? (those with gas heating) Melb 19Jul 20, 2011 9:38 am 3timesbuilda, do you usually work with home machines that are switched on and off daily, and in an area that experiences large temperature changes? Because that's a totally different situation to 24/7 RAID servers in a climate controlled environment. If the climate is controlled and the drives are very rarely started up, then of course the temperature when the drive is switched on is not going to be a likely cause of failure. Edit: This is turning into too much of an argument for my liking, I would like to keep it friendly So I've deleted the original paragaph that was here, it didn't have much point. cmhamilton, you don't need to start a drive at 5 degrees to have a temperature increase of 20 degrees over an hour. Starting it at 15 degrees or so will do it, in my experience. That's cold enough to get funny noises and complaints from the drive as it warms up.
