Do hard drives eventually fail?

How Long Will Your Hard Drive Last?

Death, taxes and hard-drive crashes: nothing else is certain. At least, that’s how Benjamin Franklin would have put it, had he lived to be an IT guy, too. We can’t help you with the first one just yet, cloud storage for the consciousness is still like a couple of years off. For taxes, our accounting software reviews can help lessen the pains of adding and subtracting. This article, however, is about sputtering hard drives.

The unfortunate reality is that predicting a hard-drive crash is a crapshoot. The truest thing we can tell you is that all hard drives go kerplooey, eventually. As much as you might think that new SSD is unbreakable, the reality is that time is not on your side (nor has it ever, as you can read in our history of the hard drive).

Coming up, we’ll give you the statistics, then offer some helpful tips about how to recognize your hard drive’s imminent eruption into flames (hyperbolically speaking, we hope). We’ll also harp some on the importance of backing up your data before things get that far.

You can jump to our best online backup roundup if you’ve already decided luck isn’t the best backup model for you. If you’re a gambling man, we’ll also talk data recovery should your hard drive fail, drawing on inspiration from our best data recovery software guide.

Hard-Drive Failure Rates

There isn’t much in the way of data available out there about hard-drive failure rates. The most comprehensive data, which everyone likes to reference, is compiled by Backblaze. The results of the study, while neat, provide a very limited answer to the question of how long your hard drive will last.

The Backblaze study began in 2013 and the most recent results were reported in February 2018. Analysts have been tracking the failure rates of several different brands and models, totaling over 90,000 drives in all.

Over the course of the study, from April 2013 until the end of 2017, the average annual failure rate for HDDs works out to two percent. Failure rates were inconsistent across various models, with HGST, a Western Digital subsidiary, putting up the best numbers with a 4TB drive: 130 failures over the course of 8.7 million drive days for a miniscule 0.54 percent failure rate.

The worst rates were reported from two Seagate models at 15.34 percent and 29.08 percent (other Seagate models performed much better).

There are a couple of problems with the study when it comes to predicting the potential for failure of your own hard drive. For one, the Backblaze drives are spinning in secure data centers with raised floors, secure racks, HVAC systems and climate controls. That’s a bit different than a desktop crammed under your desk, absorbing your kicks and breathing in flakes of your dead skin.

The other problem is that Backblaze only uses HDDs in its data centers, while today’s laptops and smartphones, along with increasingly more desktop computers, use SSDs. SSDs use chips to store data, making them far more reliable than HDDs, which use spinning platters and mechanical arms that are prone to breakage.

There have been a few studies on SSDs, but unfortunately most of those are based on data center tests, too. One of the most well-known was conducted by the University of Toronto and Google, in which researchers found that SSDs had to be replaced about 25 percent less often than HDDs. However, while lasting longer, the study did find that SSDs suffered from higher rates of data errors.

That mostly lines up with what Network World says on the matter, which is that consumer SSDs have annual failure rates of well under one percent. If your a home-computer user, then a greater-than 99 percent chance that your SSD won’t fail is probably fine.

If you’re an IT professional charged with protecting valuable business data, then your goal is likely a mark of five nines (99.999 percent) uptime. In that case, a fraction of a percent failure rate probably seems like the end of the world.

The short answer is that we don’t know how long your hard drive will last. It’s been generally observed that if your hard drive is going to fail, that failure will occur either in the early days of the hard drive’s life or after around four years. Early failures are due to manufacturer defects, which sometimes make it past QA tests. Late failures are due to normal wear and tear.

For most home-computer users, it’s far more likely you’ll end up replacing your entire computer before your drive ever crashes. Then again, you could be one of the unlucky ones.

To help ensure that you aren’t, there are a few steps you can take, including recognizing the signs that your hard drive is at the end of its road.

Signs and Causes Hard-Drive Failure

Stellar Phoenix, makers of Stellar Phoenix Data Recovery, put together a handy table of seven early signs of hard drive failure that will help you avoid troubled waters.

Symptom:Possible cause:Data protection steps:
System crashes (either often or under heavy use)CPU or memory overheating.
Bad sectors on hard disk drive.
Backup your data immediately.
Run computer, memory, or hard drive diagnostic.
Verify dust build up on the computer’s ventilation areas.
System takes longer than anticipated to bootHardware failure.
Hard drive failure.
Failing sections on the hard drive.
Backup your drive onto an external drive.
Execute system diagnostic.
Missing filesFile system corruption.
Virus attack.
Hard disk failure.
Backup data.
File explorer takes a long time to display folder contentsFile system corruption.Backup data.
SMART errors indicated by hard disk diagnosticLogical as well as physical errors.Backup your data.
Copy data to the drive.
Blue screen of deathSoftware or hardware issues.Use Windows operating system repair tool.
Remove bad device driver.
BIOS fail to detect the hard driveUse of unreliable power source.
Either too high or too low power supply for UPS.
Use branded UPS.
Switch off system when not in use.

While many of the symptoms listed above can mean other things, they’re all generally indicative that something is wrong with your computer. If you haven’t backed up your computer, at this point you might want to get on that.

Hard-Drive Backup: Prevention is the Best Medicine

Backing up your hard drive is a smart thing to do, even if the small percentage of a chance your hard drive might fail doesn’t scare you off. There are many other ways to lose data other than a disk crash, including human error, natural disasters, malware and software corruptions.

Backup tools replicate not only your files, but your file system as well. That way, if you have to switch to another hard drive, you can recover everything as it was with just a few mouse clicks.

When backing up your hard drive, you can elect to go with a local backup option like an external hard drive or a network-attached storage (NAS) device. If keeping data locally seems like a bad idea, there are also online backup options, which means your files will be kept in servers in secure data centers.

The approach most data-backup gurus suggest, though, is to follow the 3-2-1 backup rule, which calls for storing backup data both locally and in the cloud to gain the advantages of both.

If you’re looking for an affordable online backup solution that requires little effort to implement, Backblaze is a good choice. Not only does the company have the easiest backup tool to use we’ve reviewed, you get , which is the best backup deal we know of.

Hard Drive Crashes and Data Recovery

If you fail to backup your hard drive and it crashes, there’s still a chance you can recover your files. You could take your drive to a computer repair professional, although recovery in that case might cost you hundreds of dollars or more.

A better first step is to try and recover it yourself, which you can attempt with many of the tools mentioned in our buyer’s guide for the best data recovery software. After having put all of the best options through more testing than we care to remember, we personally recommend Stellar Phoenix Data Recovery.

To recover data from a crashed drive with Stellar Phoenix, you need to attach that drive as a slave to a working computer with recovery software installed, then run a scan. If you’re dealing with file corruptions on a drive on its way out, you can run the recovery program on the failing computer, though you’ll want to have another drive ready to transfer it to once recovered.

We have a full Stellar Phoenix Data Recovery review you can check out, but here’s a quick look at the process in a video created by the company itself.

Overall, Stellar Phoenix is a pretty simple tool to use. While designed for IT professionals, it’s suitable for less experienced users, too. The company also makes a dedicated tool for recovering deleted or corrupted images, which ranks as our pick for best photo recovery software.

Final Thoughts

There’s no simple way to calculate the lifespan of your hard drive. It depends on whether you’re using an SSD or HDD, how much abuse your computer endures and luck. As a rule of thumb, once you hit the four year mark, consider yourself in dangerous territory, though really you should always be on the lookup for the signs of impending demise.

If you do experience a data loss due to a drive crash or corruption, Stellar Phoenix Data Recovery will often work to bail you out. However, it’s not foolproof, and neither is taking your computer to an expensive data recovery expert.

Major Signs and Causes of Hard Drive Failure (Here’s What To Do)

Hard drive failure is one of the several leading causes of data loss! Surprisingly, while hard drives are one of the most critical vehicles for data storage, they’re also the least thought about. Think of the last time you gave serious thought to the health of your hard drive? The fact is, hard drive failure happens and it’s more common than you think.

Did you know?

In the US alone, over 140,000 hard drive failures occur every week. Do you know how many hard drives crash due to mechanical failures?

Over 60%. The other 40% happen due to misuse and accidents.

You may never face a hard drive failure, but if you do (very high chance) , it could be the worst day of your life.

In this blog, we’re going to take you through the Major Signs and Causes of Hard Drive Failure and what to do just in case.

But before we dive in, remember that your top priority should always be to create an extra backup of your data. This is to prevent data loss in case your primary hard drive fails. Neglect in protecting your data will leave you vulnerable to hackers, malware, and much more!

In case you don’t have an existing backup, see this article on best backup strategy. Looking to back up your data? Check out Best Backup Strategy and Practices to Protect Your Data

Symptoms and Signs Of A Failing Hard Drive

Computer freezes, slows down or displays a blue screen

So you’re finally free from a hard day’s work and looking forward to the next episode of your favorite show. But the moment you’re about to dive into it, your computer freezes, slows down or just starts displaying a blue screen.

Now such a breakdown can be caused by a host of reasons and a failing hard drive could be a major driving factor behind it. Immediately call a DriveSavers expert in case the problem persists. The recurrence of this problem is a major sign of an impending hard drive failure.

Data gets corrupted and the buildup of bad sectors

Here are a few signs of corrupted data surfacing. If you encounter any of these, it’s a major tell-tale sign your hard drive might be about to give up.

  • File or folder name has become scrambled
  • Open, move, or save files and receive random error messages
  • User can’t open files
  • Files contain corrupted data
  • File or folder has disappeared

There are two main reasons for data corruption. Either it could be a virus or just an accumulation of bad sectors on your hard drive.

Role of bad sector accumulation in hard disk failure?

Basically, the magnetic media that resides on the platters breaks down as time goes by. This is simply a sign of aging hardware, so there’s nothing you can do to prevent this. In fact, all new hard drives have defective or carry bad sectors.

When these bad sectors are discovered, they’re replaced with spare sectors on another part of each platter. But once all the spare sectors are used up the hard drive’s data integrity is compromised.

The more bad sectors in your hard drive, the higher your probability of issues will be with corrupted data and hard drive health.

Unusual and Alien Sounds

If your hard drive has started emitting alien sounds, it usually spells trouble for your hard drive. There are a couple of unusual sounds you should be on the lookout for.

  • “ Click of Death ” This is a repetitive sound caused by the head trying to write data but failing in its operations. It keeps on trying again and again causing it to make a consistent clicking sound.
  • Screeching noises or grinding could mean your hardware’s bearings or spindle motor is failing .

Major Causes Of Hard Drive Failure

The Read/Write – Heads Crashed

A head crash occurs when your hard drive’s head physically touches the platters. This issue can be caused by either an electrical malfunction between the logic board and the head or trauma to the drive.

Did no one tell you to not carry your hard drive around? If you dropped it and heard a crashing sound, chances are, you just caused an HDD head crash!

Whether your hard drive is spinning or not, if it was dropped or not, the heads can slap or crash into the magnetic layers of the platter.

The Hard Drive’s Spindle Motor Malfunctioned

Spindle motors are powerful. They spin the platters at over 7200 RPM! If your HDD platters don’t spin, the HDD heads can’t send and receive information thus rendering your hard drive useless. This situation is called a Spindle Motor Malfunction.

Your hard drive’s Spindle Motor can give out due to a number of reasons

  • Deteriorating Lubrication
    Vibration levels and operating speeds can be affected by inadequate lubrication leading to a spindle motor malfunction.
  • Contamination
    By contaminating your hard drive’s bearings with a variety of fluids and particulates, such as coffee or a glass of wine, smoke etc, you significantly shorten its lifespan.

Types of contamination

  • Coolant Contamination
  • Chip and Air Contamination
  • Mishandling leading to hard disk drive failure

Spindle motor failure produces a faint beeping noise as we warned earlier in this article. So if you hear any strange sounds coming from your hard drive, power down your computer right away!

If the motor failure hasn’t compromised the platters in any way, there’s a good chance you can fully recover your data. This is a great sign! But trying to handle this situation yourself will make it worse.

Motor issues can only be addressed by a data recovery engineer if you want to keep your data recovery hopes alive, call DriveSavers!

The Hard Drive Exhibits PCB Problems

Power circuit boards or PCBs, are the lifeblood of your hard drive. PCBs are responsible for enabling the read/write heads to create and interpret data. Inside the hard drive, there’s a tiny arm powered by an electromagnet that changes the cell orientation. The microcontrollers within PCBs power this tiny arm. If the PCB fails, the hard drive will surely fail.

Symptoms of having a PCB problem can be a burning or smoke smell, an unresponsive drive, a drive that overheats, the computer prompting you to format the drive, strange file errors, and more.

Adaptives Deviations

Within every hard drive’s firmware is a list of its imperfections—literally! Hard drive manufacturers know their product will eventually fail so they provide a list of those imperfections called the adaptives list or adaptives table. When your hard drive is calibrated, they take into account these potential issues.

But over time, every hard drive’s operation changes. And as a result of these slight physical changes, the read/write heads get off track. This is called adaptives deviation. The adaptives originally set forth by the manufacturer remain the same, even though the physical operation of the hard drive shifts. When this happens, your hard drive can’t read or write data.

Natalie overcomes a data loss nightmare

What TO do . . .

In today’s world, data is important. This is because we all have so many memories, pictures, videos, and miscellaneous important files stored on our PC. We just never think about losing them and instead take hard drive health for granted.

Here’s a little challenge. Sit back and ask yourself, “Is the data stored on my desktop or laptop important to me?” We’re sure the answer is a no-brainer. The next question to ask is, “what have I done to ensure its safe keeping?”

We know you’re busy in everyday life, it can often be hard to think about your hard drive’s health. In our vast experience, we are often approached by individuals facing hard drive failures. We get so many queries from users who never created an extra backup of their data from the start. Don’t know how to backup your data ? We have some suggestions.

The path to preventing data loss begins with the understanding that hard drives fail. They are bound to eventually. Either through age or damage. So what should you do when your hard drive fails?

You may be able to self-diagnose the issue if you are computer savvy and are willing to do some research. But diagnosing the problem is one thing, repairing the damage of data loss properly is entirely another.

Our sincere suggestion to you is; never be seduced by the seemingly endless amount of data recovery tools on the internet. Data recovery isn’t a DIY project which you can just casually tackle on the weekend!

In fact, attempting to repair your hard drive will probably result in irreparable damage and permanent data loss. Every hard drive failure, no matter what the cause, is best addressed by a data recovery specialist.

So don’t waste your time, energy and possibly lose your data permanently by trying to fix your own hard drive. Call DriveSavers today to ensure the best possible outcome for your hard drives data recovery.
