Interesting story. I bought a hard drive from a garage sale, as I was about to wipe it I found over 4000 photos of this guy in his college days, photos like college parties, holidays, friends etc all dating back to 2003, also a copy of an old Counter Strike game. Interesting enough, I was surprised all the files were there and not corrupted from being turned on for the first time since the last file was written in 2004. I tracked down the guy and found out he lives in another state, currently in the process of reuniting him with the hard drive he has lost for over 15 years!

You don't need to add a dedicated HDD cooling system, just install a case fan to blow air over / in between your drives all the time. Doesn't have to be a noisy high performance fan, a regular low RPM silent fan is more than enough, as hard drives don't generate that much heat in compared to other components like a processor or even a MB bridge, any amount of fresh air that constantly circulates around them will do the trick. I also have extensive experience with PC endurance and data storage, providing your drives are adequate quality manufacture cooling more than doubles their life expectancy.

HDDs in my experience are tough resilient beasts. I have a bunch of really old drives from the 1990s ranging from 10 to 80 GB that I have submitted to constant full erase/ write cycles performing back ups on a close to daily basis for 9 years now. Intending to test their durability I even have had them operate with poor cooling becoming really hot, reaching almost 70c and operating like that for hours. half of those drives were reported as imminent failure by monitoring software with less than 12 working hours left on them when I first got them. other than re magnetizing a handful of sectors via software on a couple drives None of them has given me any trouble and all have worked way longer than the predicted 12 remaining hours, even the "crappy" IBM travelstar drives.

Believe it or not, but one of my drives once failed, because the screw holding the arm, had come loose. Read errors all over the place, clunky sounds. I broke open the drive, mounted it again, used the drive one last time, to transfer the data, and threw it away... Back in the days, hard drives would last about 2 years, before software errors would take place. The harddrive would still be good, but in desperate need to move the data around with DEFRAG. The "Scandisk /surface"-command was another option to check for software errors, however, when a sector was getting bad, it was better to move the data with DEFRAG, or just reinstall Windows again! Back in the day, people didn't have access to good software as people have today. You'd know when software errors would start occuring in Windows, when it would start to behave oddly (specially if no defrag was performed for more than one year). Some hard drives I had between the 1990's to 2010, lasted 5 years, some only 1 year. The older drives, Western Digital was one of the worst, paired with Transcend, while Toshiba had one of the best (longest lasting) hard drives! Samsung was somewhere in the middle, and Seagate was somewhere on top, between Toshiba and Samsung. Since 2010 all my harddrives have been replaced by SSD's, save for external harddrives. And the keeping of data is continuously becoming more and more difficult thing to do, without the purchase of a RAID server.

Although laptops do have designs that can prevent vibration and shock to the components including HDD. Like my HP Elitebook 8440p for an example, it has a metal case with one screw that can keep the HDD stabilized so that none of what you had mentioned that can lead to HDD failure except temperature. Also you had failed to mentioned about OS and on how the manufacturer brands could be affected. Like my father's PC had a 1TB Seagate HDD and it was somehow running 100% on Windows 10 for a while in some occurences.

Does it really matter, aside from battery life? Typically a HDD in a secondary role will outlast a laptop, and the low temperate isn't all that significant, meaning it would have to be tens of degrees higher before you could expect that to reduce lifespan below another failure modem but again, heat = power consumption and it's great to have storage that is only using power when needed, particularly in a mobile, battery powered application.

Thanks for the video. Dell had a 50% dead-on-arrival rate for computers shipped to their customers in their early years. (Note: I edited and reworded this post without extreme sleep deprivation choosing my words for me.) The problem was largely due to a single cause, hard drive failures. Something had to be done. Dell invented a new term, the "hard drive touch". What a hard drive touch referred to was any time a computer hard drive was picked up, moved, vibrated, dropped, tossed, or bounced. Some of these words sound... crazy. Tossed? Why would hard drives be "tossed"? Keep in mind how Dell started. Dell helped pioneer the idea that computers could be manufactured to order, per the customer's specification. Then, the computers were only available via delivery, through the mail. During shipping and handling, Yes; often computers were dropped, tossed, or bounced Dell started at the hard drive manufactures and followed the hard drives all the way to final delivery counting the number of "touches" along the way. The total number of "touches" had to be greatly reduced. Conveyor belts, factories, fork lifts, and just about everything else in the supply chain all had to be redesigned. This was very expensive, but it paid off. Dramatically improved, dead-on-arrival statistics proved it. There was quite some delay, but it was Dell's investigations that lead a consortium of hard drive manufactures to add a new feature to all disk operated hard drives, "parked heads". One of the worst things that can happen to a drive, is that the read/write heads can bang into the disk's surface, damaging the read/write heads, and the data they are attempting to read. "parked heads" was a concept that when the drive is not reading or writing, the read/write heads should be safely parked off to the side, away from the disk's surface. This allowed for drives to be much more damage resilient. Hope this helps. If you enjoyed this comment, please do me two favors. One: click the like button on Chris's video above, and Two: Tune into my video comments 30 years from now, when I share a wonderful tale of how a little KZbin channel called Explaining Computers helped change the world for the better. : ) Again, thanks for the video.

The last minute of the video is actually the most important of this wonderful video. There are reasons for early HDD failure, but if you avoid harsh treatment, hard drives are spectacularly reliable and long lived. I fished a 100GB 2.5 inch IDE out of a dead laptop that had been resting untouched in my garage for ten years and recovered every byte on it. Probably 40 GB of actual data. I simply don't shake or bake my drives and they simply keep on humming along inaudibly. HDD's are also spectacularly inexpensive. Jewels for a pittance. Unbelievable what you can get for fifty bucks. You can keep your modern SSD , with built-in failure in a couple of years, and I'll keep enjoying my backward, care-free existence. I could be wrong, but I would hazard the guess that consumer computing is unprepared for the massive wave of data loss to come, as immature back-up practices collide with SSD end of life in a couple of years. Looking for someone out there to correct me.

It never gets mentioned because there are few to no applications where people are running HDDs in non-climate-controlled areas on a concrete floor, and even then, the floor has nothing to do with it. If you just mean a cool basement floor in winter, no, that is nowhere near cool enough to cause a problem if the room is otherwise a hospitable (to humans) temperature, and opening a window in winter does nothing to my fans, in fact I have ventilation fans directly exposed to outdoor freezing temperatures. They merely need a lubrication that stays effective in the temp range of startup as well as operational temp.

My experience is that it does matter because i live in a place where temperature changes of 20c to 40c can happen if i want some fresh air by opening a window, clearly not something you've had to think about. Computers are used in all sorts of places, not just at home on a desk. In the facebook data center where i work in Sweden, built here for the cold winters, we have to be very careful about temperature regulation as you may guess. May i recommend to you, look at googles study on hard drives so you can understand the lubrication is designed and proved to run best at 30 to 40c. temps below 10c can cause greater damage on start up, like anything mechanical, it will have an effect on its life span.

@@RetroTinkerer The head actuator of less expensive hard drives in the era of the original IBM XT/AT is exactly what is not a servo. They are stepper motors that jump to align to the next coil each time they are powered. It is just assumed the head will be aligned with the track meant to read. (There is always some amount of slop, which is a problem.) What makes a head actuator a servo is the feedback to the motor derived from the track meant to be read, as it is read. The feedback is what pushes the head to align with the track. Stepper motors use "dead reckoning." Servos home in to the right spot. Hard drives in expensive mini-computes already had hard drives with servos, and so did some improved floppy drives, but the price had to come down to be usable for people who could only afford an IBM AT. The spindle motors (which turn the platters) are not stepper motors or servos. One of the 8 inch floppy drives I bought (before the IBM PC era) cost about $400, which is something like $1500 in today's money. The price of the cheap HD's for an IBM XT were (at first) around $2000, or $8000 in today''s money. That would be a lot cheaper than what a HD for a mini-computer would have been.

I find it amazing that you haven't talked about "disk metal extension" over time. Indeed for HDs that have been spinning 5-8 years (yes it's common on servers), the disk has a tendency of expanding. Thus if you have to turn off you disk long enough for it to cool down from its "nice and warm working temperature", it might shrink enough so the head becomes unaligned from it's previous format. Thus rendering the disk unreadable, and causing it to be unable to boot anymore. Rare but I've seen it twice in my life.

Bit of a sigh to open by saying HDDs fail for many reasons but SSDs only when reaching max specced writes. You even include manufacturing defects for the HDDs but don't consider them for SSDs. Also, rubber mounts make very little difference. They are not shock absorbers, so they can only absorb high frequency vibration, and even there you'd need more elaborate constructions to isolate the drive from the case, and usually you have to do that to shield the case from the drive's vibrations more than the other way round, because most harddrives vibrate noticeably. As for harddisk coolers, it is much better to pass on that (especially one with little surface area as the one shown) and instead put the drive in a fan air flow path. That alone should suffice for any situation, even just a silent fan. Very mild direct air flow is multiples better than none at all and still much better than passive air flow from case underpressure currents or such.

But SSDs are fairly likely to fail simply from component failures, which happen unexpectedly and can cause data corruption from mild to severe, or render the drive completely unrecoverable. While exceeding the write capacity is something you should be able anticipate, since you can easily check how many writes you've officially got left. And having an SSD stop working due to exceeding write capacity is not scary at all. All the data can easily be retrieved without problems. So one should only care about component failures, not at all about exceeding the write capacity.

It's a blessing when SMART tells you that your hdd will gonna fail soon because you can backup your important data. Many hard-drive sometime just "suddenly dead" even though SMART monitoring software like crystal disk info or HD Sentinel tell us that hard drive are fine or 100% healthy.
@Dowlphin9 ай бұрын
Should be common knowledge by now to not assume that anything labeled as "smart" is smart. I have had a HDD and an SSD fail recently for unexpected reasons. One was spun up only for differential backup every couple days but had severe data deterioration and positioning issues at 10 years of age (masked because new writes from the backups didn't show any issue), and I had a Samsung SSD experience bit rot that the firmware is said to specifically avoid by refreshing old stored data.

Years ago, back before many of you were born and before machines like the VIC-20, TRS-80 or the Commodore PET, the relatively non existent computer industry (there were big firms like IBM and Honeywell making huge mainframes but nothing for the home user) was engaged in an informal debate as to how to cheaply implement computer technology into homes, hospitals, elementary schools and small business. One of the initial topics was memory. Industry used large tape drives or punch cards to store programs and data. The fledgling home computer industry didn't want to go this route. Their idea was to store as much data as possible electronically without cards, tape or a very primitive optic drive. The problem was it couldn't be done. The cost was too prohibitive and the technology to cheaply manufacture high density solid state electronics was just not there. Technologies after the development of the transistor such the Op-AMP and the four NAND Gate chip were HUGE. So the industry had to turn to cassette tape drives, floppy disks and eventually CD/DVD burners and HDD hard drives (in early drives those disks were made from glass and weighed a "relative" ton causing many spinning motors to burn out after less than a year of use) . The SSD drive was where the consumer computer industry wanted to start and it took almost 50 years for it to get there. Today the HDD is on it's last legs. The detour is finally over. Already gone are punch cards, tape and floppy drives and almost gone is the DVD burner. The only reason the HDD is still readily sold is due to inventories and third world manufacturing costs. Once the inventories are gone so will be the HDD. For all my clients I am switching them over to SSD. Any HDD implementation is done externally. I am much older than the presenter of this video and I can say it has been a fascinating ride these past 63 years. When I started working in consumer home electronics a home computer was just an "Orwellian." concept. The Vacuum tube would still be king until 1970 and an ipod was a transistor radio with a crystal earphone. I will not live to see it but I believe some form of implantable computer technology (either biologically or electronically) will be dawning soon in the next 20 years

My computer is now over 10 years old (bought in August of 2010), but initially I only had a prebuild that would fail about 4.4 years later. Then I used a laptop for ~2.8 years, and after that period I finally built my own PC using working parts of my prebuild (CPU, RAM, mainboard, hard drive, DVD/CD drive) and bought the other parts online (case, power supply) since the ones of my prebuild were too small / weak for what I had planned. As for the graphics card, I was lucky and got a Zotac GTX 470 from a friend of my sister which I used for ~1 year although for some reason after a summer vacation (I had it for ~8 months already) it suddenly "died". However, I could still use it without drivers but it stuttered _a lot_ and I think sometimes it would even have visual artifacts on the screen. Well, needless to say I could barely play any games or even just watch videos / browse the web smoothly with that "zombie" of a card... Fast forward a few months in the autumn of 2018, I got my new graphics card at last! It is an MSI (AMD) Radeon RX 570 8 GB Armor OC - which I still use today. :) So this is the current state of affairs. Sorry btw, this turned out to be an essay lol

Datafade is not a joke. I am mega paranoid about it, full backup refresh every 6 months. Just be sure to refresh backup disks one at time, use a surrogate disk as a temporary backup to your backup in case of failure during the refresh. If you really want to retain your data, have a distro stick to boot from during file copy operations with your backups. Dont use windows, Microsoft filed patents to compare your files to known hashes they are paid to look for and auto-delete them. Its still in the development stage, but it will eventually make it into the update pipeline, and I suspect they will not tell you. Plug your backup with all your movies and music into windows 10... and.. its gone! That's what they hope to roll out. Dont play games with your files, do data management and wrangling in linux.

it's only paranoia. Rewriting all the data every 6 months is straight up insane, even every 5 years makes no sense. In fact, it makes no sense to do that ever, since the drive can fail anyway. All you need to do is to check that the data is readable, nothing more. And thinking that Windows will read your every file, really? That would absolutely never happen. What's this patent you mention? I wasn't able to find anything related to hashing the contents of files.

SMART was originally intended to catch predictable failures but in actual implementation it rarely catches anything until it's too late. This was apparently due to concern that such predictive information would likely increase in-warranty repair attempts and could provide necessary legal evidence for class action lawsuits. Instead of reporting failures before your data is lost the drive plays musical chairs with failed sectors until the unit has passed well beyond the warranty period and the defects begin to exceed the drive's ability to hide them. At which point it's time to buy yet another drive from Western Digital (which now includes Hitachi and Seagate).

When noodling around in the linux man pages, I saw some peculiar, forgotten, or ignored stuff. At one time, in the old days, the way to take care of bad sectors, which normally increased, was in the file system. It wasn't internal to the HD. I believe you can still have failing sectors marked for non-use, if you care to. Another thing: At the factory, before you get the HD, they map out bad spots, because all platters have them.

Intending to test their durability I even have had them operate with poor cooling becoming really hot, reaching almost 70c and operating like that for hours. half of those drives were reported as imminent failure by monitoring software with less than 12 working hours left on them when I first got them. other than re magnetizing a handful of sectors via software on a couple drives None of them has given me any trouble and all have worked way longer than the predicted 12 remaining hours, even the "crappy" IBM travelstar drives.
