When Will Your Hard Drive Fail? 297

jfruh writes: Tech writer Andy Patrizio suffered his most catastrophic hard drive failure in 25 years of computing recently, which prompted him to delve into the questions of which hard drives fail and when. One intriguing theory behind some failure rates involve a crisis in the industry that arose from the massive 2011 floods in Thailand, home to the global hard drive industry.

      Sounds about right. I've had two crashes, one was back in 2006 and it was a raid night in WoW, the drive head of my main drive crashed. The other was a SSD failure, when I was writing a term paper. Luckily in both cases I used a triple redundancy solution for my backups and was up and running again in a few hours. I learned way, way back in '91 that if you don't have a backup you're up shits creek.

        Yes. I bought a new drive to replace my old PATA drive. The new SATA drive is to take its place. Now, the copy operation I tried failed because there were too many bad sectors on the old drive. So, it'll take some massaging and a different method, but I'll be able to salvage the data. The drive, at that point (migrated off and useless) is then free to "die" a peaceful and convenient death. Oh, and the old drive is SMART, but no errors were generated warning of the issues, until I tried moving off it.

        At the minimum, the guy should have at least an external hard disk and Mozy, Carbonite, BackBlaze, or another provider. The external HDD is for the backup program to allow for a bare metal restore of the box, and saving it on a remote provider helps with retrieving the files if the computer and its backup drive become inaccessible (destroyed/stolen/etc.)

      • That is basically what I do. I copy over all the important files and my data to a external HD. I have used automatic backup systems and bare metal recovery options in the past. To me they have never been worth the trouble. Seems like every time I try to recover from one of these something isn't comparable or something is missing like a driver.

        To me its just easier to reinstall and copy over the data from backup once I replace the drive.

      I have to disagree - Yes, I personally go for a waaay more paranoid backup approach, but just backing up to an external USB HDD (though with a "real" backup, not his manual drag-and-drop BS) puts someone a whole world of hurt better off than 99% of computer users.

      If Grandma calls and says her HDD died and she hasn't "run that DVD backup thing" in a few months, well gee, sucks for you, granny! If, however, she calls and asks for help getting her nightly USB drive backup reinstalled to a new computer, hey, cool, she's lost almost nothing.

      Now, sure, perhaps her computer got hit by lightning and toasted both. Perhaps her house got flooded and nothing electronic in it still works. Perhaps her PSU went bad and toasted every component in the machine (although even then, USB devices will often survive that). Perhaps she caught a cryptolocker-type virus that ate the backups as well. Sure, a single connected backup device has a lot of points of failure in common with the system drive itself. But in practice, it drops that "lose everything once every few years" down to "lose everything once in a lifetime".

      Why? Most people only have one computer, and really, anything in the same building is subject to most failures that are going to get a drive in the same machine. Back up often to a dedicated hard drive in your computer, or a NAS. Less frequently, back up that drive to something more secure.

      People don't make backups because it's inconvenient. An automatic backup to a dedicated drive in the same computer is very convenient, and will take care of the vast majority of failures.

    Short answer: If you actually care, you need better backups.

    If the HDD in one of my PCs dies, I don't care in the least. Restore it from last night's backup to the NAS, and call it good.

    If up to two of the HDDs in my NAS die, I buy new ones, swap them in, resilver them, and call it good.

    If my entire NAS dies, I would start to get worried, but at that point I can still fully recover (at least to where I left everything last night) from my partially offsite backup, an exact snapshot of my NAS that lives in my detached garage.

    If my house and garage somehow both get destroyed at the same time, I would lose a lot, but do still have my most important data mirrored offsite... Though at that point, I probably have more important things to worry about than re-ripping my music library. :)

    But if you care about when any one particular drive will fail on you, you've already accepted the eventual catastrophic failure and loss of your life's work as entirely acceptable.

      Don't forget the bits where you verify that the 'backups' actually restore into something useful; such verification ideally including integrity checks of every file; but at the very least a sanity check of the backup.

However, there is a well know law of physics which states that the more time that passes from your last backup the more likely your hard disk is to fail more or less regardless of the dis's age and the odds of the damn thing failing increase exponentially if you have been doing something really important and/or time consuming in the interval.

    Friends, I am hear to bear witness! Once I lived in darkness and sin, and I have suffered the pain of my transgressions.

    I kept one copy--yes friends--one copy only-- of data I believed was important.
    One fateful day Providence saw fit to show me the error of my ways. The foundation of rust on which my data was build collapsed into the sea of oblivion and the data thereon was lost forever to the void. Yes, Lost! Lost and without hope of salvation!
    But this was a blessing, Friends, a blessing and a revelation for it was at that moment of humiliation and regret that the truth was shown to this poor sinner!

    (cue rising electric organ chord)

    That data is gone and despite our mournful remembrance of our departed files, they can never be brought back from their eternal sleep.
    But, friends, that data was not important. For verily it is written that none may know the hour that the data will be lost, only that the data will be lost. And it is also written that data of which there is only one copy is not important data.

Spend ye a small sum today for truly I say to ye that if ye are afraid to purchase an additional drive, then surely professional data recovery is beyond your means! Trust not in single parity for it is written that filesystems have grow huge in our greed for virtual machines, high resolution, and hoarding. Yea, though RAID5 was once a stalwart guardian against the failure of a single drive, RAID5 is dead and its promises are vanity for surely on the day the first drive fails thou shalt begin to rebuild thy array and before thou canst complete thy task the second drive shall fail and on that day there will be no salvation but only the wailing and gnashing of teeth.

    Scrub ye regularly thy filesystem and furthermore perform regular smart long tests, but never at the same time, for it is written that a scrub and a long test shall persist unto eternity and never complete.
    Implement well thy automated email notices and read thoroughly thy notices every week. When thy status report does not arrive at the appointed hour and when thy daemon sends thee an unexpected email, remain not idle but take action to investigate and resolve thy anomalies.

    When thee hast constructed and filled a robust and well-monitored filesystem name it thy primary file server and do not rest in false security, but instead do the same a second time call this thy secondary file server. Locate ye thy secondary server in a place separate and apart from thy primary server and schedule ye regular backups from the primary to the backup filesystem. Monitor ye well the status of the backups and should the report of successful replication fail to arrive at the appointed time, investigate thy primary and secondary servers and all the links between. For in truth it is written that RAID is not a backup.

    Go forth in peace my brothers and sisters in the knowledge that while it is inevitable that thy data will still someday be lost, this day will come to pass after all else has been lost and on this day the data will truly not be important.

    I work for a small repair/IT firm and our experience largely matches backblazes when looking at brands. We rarely deal with NAS drives or larger capacities so I cannot speak to those. There is a 2007 study by google into predicting HDD failure. Per their data, about 50% of drives fail with a discernible warning in SMART. However, that warning requires manual watching as what they saw is that any type of pending or reallocated sector is indicative of failure. However, a few pending sectors may not be past the manufacturers threshold for failure. Therefore, 50% will fail with no warning, that is a given. The number probably approaches 95% or more if you are relying on tools that compare SMART stats with the manufacturer thresholds. You need tools that allow you to set your own thresholds or look at the numbers manually on a regular basis. My personal (and uneducated) assumption about this is that most of the pending/reallcoated sectors are caused by the magnetic domains on the surface of the platters weakening over time. Given the areal density of modern disks, slight defects in the coating or other chemical degradation could be to blame. Basically this would be a form of bit rot, and makes a sort of sense given the failure rate seems to spike for all manufactures at about the same time frame. Lastly, all drives will fail. Also other events happen, be it fire, theft, crypto viruses that encrypt your files and local backups, accidental or malicious deletion, etc. An on-site backup protects against none of those in any reliable way. Add in the fact that SSDs (which also will fail for other reasons), and are more difficult (expensive) to recover from are gaining traction, an off-site backup is the most logical solution, be it cloud, safe deposit box, etc. I am not here to advertise so I won't name names, but the solution my firm sells is cloud-based with both file and system image backups, including versioning and archiving. It also allows for a local copy of the backup set to be stored on a suitable drive. This allows for super fast recovery of large backup sets, with the online version as a backup. The backup set is fully encrypted with a choice of encryption standards and the ability to have only the customer have the encryption key (normally we keep the key as well, but we do not have to). If you are serious about your data, you should look into features like that for yourself. Relying on manual on-site backups can only be a recipe for eventual disaster.

    I personally like to put RAID-1 in my end user systems. The data goes to a RAID-6 array. The array is duplicated to another live. Never lost any

    While interesting, the devil is in the details, and these are more less all generalizations. So yeah, don't go out and buy a Seagate built with those specific specs. That said, usually you can't tell wtf you are buying until you have it at home, crack the box and look at the serial numbers and such, at which point you are probably SOL anyway as it is yours now.

    The analysis looks at the Hitachi drives as the best, which were acquired by WD. However they were acquired by Hitachi from IBM before that. IBM had it's own scandal for anyone that cares to remember for 1) The "DeathStar" class of drives that had an industry worst failure rate once upon a time for whatever reason, and 2) leaked documents about warranties and planned obsolesce, in that an approximate 3 year failure rate was more less built into drives for commercial reasons (i.e. to sell more hard drives). They were designed for 3 year lifespans, though they didn't intentionally fail after that.

    Anyway it all depends. Certain drives, made at certain times, made by certain manufactures, *may* have higher or lower failure rates... This is why this topic is so hard to pin down...

    I liken it to back in the golden age of OC CPU, people would be very particular to get lots or batches of certain CPU that would perform much better than their counterparts. However it had the same issue. You buy it, usually without knowing that kind of detail, roll the dice, and hope when you open the box it is the right serial number, etc...

    Though where the similarity is really close it is by regional manufacturing. I vaguely recall some Intel CPU being make in Thailand, and others being made in Malaysia, and one being better than the other back in the day for a certain spec... I doubt it is much of a causality leap to infer that the drives made in China may be of lesser quality than those made in Thailand during that period of time...

    One other thing to remember with computer electronic is binning. Usually in *any* electronics manufacturing process there will be binning where after QA testing, a product could pass, it could fail, or it could marginally pass and be classified as another product. As you may recall, after the whole Thailand flood, either for real or imaginary (for profit), there was a shortage of drives, and the prices doubled, then tripled. It would be VERY hard for any company to not cheat a bit in the binning process when the profit is triple what they used to make. So perhaps usually drives that might otherwise be binned as marginal or failiure, were making it to market simply because the drive you used to pay 70$ for is now selling for 300$ and that is too good to pass up (particularly for short term CEO getting quarterly bonuses not overly concerned with long term implications of branding).

  • Having a quality backup solution isn't all that hard these days.

    On-site file server with a ZFS RAID-Z (2/3) storage pool. Frequent snapshots of data (hourly?). Occasional ZFS Sends to offsite location over VPN (nightly?)

    Occasional ZFS scrubbing, which validates block level data against hashes rather than just a basic checksum/parity bit/SMART check. (weekly/monthly?)
    Single drive failure? Just replace it, nothing is down.
    Multi-drive failure? Depends on your RAID-Z level, but possibly still nothing down, and

  • I once tried to back up my windows 7 laptop to a external hard-drive. It continuously failed with no good explanation as to why. Turns out The external-drive which was 2 TB had a different sector size than the laptop’s 200 MB. WTF Microsoft?!? You can’t bother to be more explicit that you need to have the right sector size before a huge backup that several hours later fails??? And even then doesn’t tell you why it failed?

    I lost several hours trying to find the cause of the problem, an

  • Google. I am sure some Slashdotter will feel umbrage at this approach, but it has worked wonderfully for me. I now have my documents synced from all my computers in one place, and as I said, backing up is done by highly trained professionals, using storage devices and methodologies far above my means.

  • I have in my possession a 1TB WD Blue which was built in 2011.

    The controller board was assembled onto the drive improperly, with the board bent over an alignment post instead of the post going through a hole.

    Eventually, this caused a power issue as some SMD or other's RoHS solder joint(s) turned intermittent through years of heat-cycling: It wasn't spinning up or being recognized in BIOS.

    I took it apart, looked at it funny, put it back together as properly as possible, and applied a rubber band to put some
