Do you stress test your new drives?

Just wondering. My friend does. I wonder if I should do that too. Thank you in advance. Nope. I backup all LAN drives daily to three internal drives and to seven external drives rotated once per week. That should catch all old and new drive failures. Lynn |

I see no need to do anything other than simply use a new drive. |

No. The most likely source of failure is one of the chips. There is no way to do a proper stress test on the electronics of a device. Well there is, but to do it well might require removing the chips from the HDD's circuit board and building a custom circuit to stress test them. You generally assume that the manufacturer of the chips has gone through enough testing to be reasonably confident that they conform to their specifications. I'd imagine the same for the mechanicals of mechanical HDDs. I'd say that if you need to stress test your HDDs, then you don't trust the manufacturer, in which case that prompts the question of why you bought from them in the first place. Many years ago I read that modern solid-state electronics either fail within the first 100 years or run for a very long time. And a hard disk is not entirely solid state Ooops! I meant "100 *hours*" of course. Perce They can last for 100 years, or if they are operating at the limits of their temperature rating (as is sometimes the case in poorly designed equipment, or if it is operated in a harsh enviroment (for a HDD - not enough airflow)) they might last a much shorter time. There will also be some that, when made, just don't turn out quite right and will fail in a _very_ short time. However as I stated, the manufacturer of the electronic components should have sufficient tests in place to make sure that the dodgy chips are weeded out before they get anywhere near the HDD manufacturer. I certainly expect that the HDD manufacturer would then run a burn-in test on their finished HDDs to make sure that they are in good order before shipping them off. If so, doing it again would be a waste of time. As for "trusting the manufacturer," if you read user reviews on line, you will find that, no matter which manufacturer, there are always people who will never again buy drives by that manufacturer. IOW, every manufacturer ships the occasional dud. I therefore run extensive tests on all my new drives. After the manufacturer has stress tested the drive, I would expect that further early failures would be from some component that simply breaks after extended use rather than not being built to the standard required to survive a high load situation. The only way to find that out is to just run the drive and see how long it lasts - little point to extra stress tests. |

I don't think that repeating the initial tests that the manufacturer should have already done will have much impact on the odds. I actually had to send a Samsung and a Western Digital back because they didn't pass the full self-test, where the drive totally scans itself. It can take hours to run and so I doubt if the manufacturers do that. It would certainly be better if they did. I didn't doubt it because such a degree of testing didn't used to be unusual in other industries making consumer products, and HDDs are business grade products as well. Now I do, though I think it's ridiculous. -- __ __ #_ |\| | _# |
