Should my HDD be making clicking sound?

If you are noticing clicking or ticking noises coming from your hard disk drive (HDD), this is usually a cause for concern. In most cases, clicking or ticking noises indicate that there is a mechanical fault occurring inside the hard drive.

What does a clicking or ticking hard drive mean?

Inside every hard disk drive there are platters that spin at very high speeds along with read/write heads that float just above the platters on an air cushion. Data is stored on the platters in concentric circles called tracks. When you access data on your hard drive, the read/write heads will move to the correct track and location to read or write the data.

Clicking or ticking noises most often indicate that there is a mechanical problem with the read/write heads or spindle motor that rotates the platters. Some common causes include:

  • Read/write head stuck and tapping a platter
  • Spindle motor bearing wearing out
  • Damaged or misaligned read/write head
  • Platter surface damage

In many cases, the clicking or ticking sound is the read/write head moving back and forth or tapping against the platter as it tries to move into position. This indicates the head is stuck and cannot properly access data on the platter.

Why is a clicking HDD bad?

When an HDD makes clicking or ticking noises, it means there is mechanical damage and wear out occurring. This problem will progressively get worse over time until the drive completely fails. A clicking hard drive has a very high chance of complete failure in the future.

The mechanical problems that cause clicking and ticking also commonly lead to further issues down the road like:

  • Inability to access or read data – With a stuck read/write head or damaged platters, data cannot reliably be accessed anymore. You may encounter frequent errors and inability to open files.
  • Data corruption or loss – Severely stuck heads or scratched platters can corrupt data on your drive leading to data loss.
  • Hard drive failure – The mechanical issues that cause clicking will inevitably lead to full hard drive failure and breakdown.

For this reason, a clicking hard drive should be addressed immediately before complete failure occurs and important data is lost for good.

What causes the head to click in a hard drive?

There are a few common causes of a hard drive head clicking:

  • Stiction – When the head sticks to the platter surface due to friction. When the platter rotates again, the heads will click as they snap free.
  • Contamination – Dust particles or gas vapors enter the drive and contaminate the head or platter, leading to sticking and clicking.
  • Impact damage – Physical impacts like dropping the hard drive can bend, misalign or damage the heads causing clicking.
  • Wear and tear – Over many years of use, the heads and platters degrade leading to instability and clicking.

Factors that can contribute to a clicking head include:

  • High humidity environments that allow gas vapors to condense inside the drive.
  • Very hot environments that warp and expand drive components.
  • Age of the hard drive and accumulated wear on heads and platters.
  • Vibration and impacts like dropping the computer.

How can I fix a clicking hard drive?

Unfortunately, there is no reliable fix for a hard drive that is making clicking or ticking noises. The mechanical nature of the issues means that DIY remedies have a low chance of success and may further damage the drive. Here are a few options to consider:

  • Send to a data recovery pro – Data recovery pros have specialized tools in cleanroom environments to repair drives and attempt recovering your data. This can be expensive but offers the highest chance for data recovery.
  • Replace the circuit board – In rare cases, the clicking is caused by a faulty circuit board. Replacing the board can fix clicks but data loss may still occur.
  • Try DIY head realignment – There are some risky DIY methods like the freezer trick or dropping the drive. These have a very low success rate and high risk of worsening the problem.
  • Replace the hard drive – In most cases of clicking drives, replacement is the most cost effective and reliable option to get your computer up and running again.

If the drive is still under warranty, you may be able to get it replaced by the manufacturer. Otherwise, an identical hard drive needs to be purchased and installed in the computer.

After replacement, your data can hopefully be recovered from the old drive by specialists if needed. Be sure to regularly backup your data to avoid data loss when hard drives fail.

How do I recover data from a clicking hard drive?

Recovering data from a clicking hard drive requires professional data recovery assistance. Specialized tools and techniques are needed to extract data from mechanically damaged drives.

Here are some tips for maximizing chances of data recovery from a clicking drive:

  • Stop using the drive immediately – Continued use spreads damage and lowers recovery chances.
  • Find a reputable data recovery company – Look for experience, cleanroom facilities, and no fix-no fee policies.
  • Do not open the drive – This exposes it to contaminants and voids any warranty.
  • Avoid DIY recovery methods – They can often do more harm than good.
  • Be prepared to pay $500-$1500+ – Professional data recovery is expensive but often the only way.

The data recovery process may involve:

  • Imaging the drive to create a full sector copy
  • Troubleshooting and repairing mechanical issues
  • Using specialized recovery equipment and software
  • Manually extracting data with forensic tools

If the platters are physically damaged from severe head crashes, data may only be partially recoverable or fully unrecoverable. But professional firms offer the best shot.

Can a clicking hard drive be fixed?

In most cases of clicking hard drives, the odds of DIY repair working are quite low. The mechanical nature of the issues makes at-home fixes challenging. But data recovery pros have tools that can repair some clicking drives.

Here are some factors that influence whether a clicking drive can be repaired:

  • Cause of the clicking – Simple issues like stiction may be easier to repair than physical head or platter damage.
  • Extent of damage – Light clicking may indicate minor issues compared to loud frequent clicking.
  • Importance of data – The cost of repair may only make sense if critical data needs recovery.
  • Age of the drive – Older drives with wear have lower repair success rates.

Actual repair techniques data recovery firms may use include:

  • Replacing or realigning the read/write head assembly
  • Replacing the circuit board or motor
  • Microsurgical platter repair in a dust-free cleanroom
  • Correcting firmware issues with a PCB swap

Diverse specialized tools like magnetic platters for head realignment and microscopes for platter surgery allow technicians to repair many clicking hard drives. But there are always cases too severe for repair.

How can I prevent my HDD from clicking?

You can help prevent your hard drive from developing clicks and ticks by:

  • Minimizing vibration and shocks – Place your computer on a stable surface and avoid dropping it.
  • Keeping the drive cool – Ensure sufficient air circulation to prevent overheating.
  • Protecting against dust and particulates – Only use the drive in clean, dry environments.
  • Having robust backups – So data can easily be restored if the drive does fail.
  • Checking HDD health – Monitor drive health with SMART status tools.
  • Considering an SSD – Solid state drives have no moving parts and won’t click or tick.

You can also have your drive professionally serviced to extend its lifespan if concerning symptoms appear. But hard drives are mechanical devices that will eventually fail given sufficient time and wear.

Are some HDDs more prone to clicking than others?

Certain hard drive models and product lines do tend to have higher rates of clicks and failures compared to others. Some factors that contribute to failure-prone drives include:

  • Cheap budget drives with lower quality components.
  • Older drive models as technology improves over time.
  • Drives from brands known for poor reliability and RMA rates.
  • High capacity drives which pack more platters and heads.
  • 2.5″ laptop drives exposed to more shock and movement.
  • Drives used in hot server environments 24/7.

According to various surveys and reports, Seagate Barracuda and WD Caviar Blue desktop hard drives experience some of the highest failure rates over time. High workload enterprise drives also click more often.

In contrast, server-grade HDDs like WD RE and Seagate IronWolf that are designed for 24/7 uptime tend to be much more reliable and stable.

Should I be worried about a ticking hard drive?

Ticking or repetitive clicking coming from a hard drive is an alarming sign. It likely indicates mechanical instability and imminent failure in the future.

Some signs a ticking drive is cause for serious concern include:

  • The ticking occurs constantly at regular intervals.
  • The ticks are loud and noticeable from outside the computer case.
  • The ticks started recently after not hearing them previously.
  • The computer freezes or is slow to respond when the drive is ticking.
  • There are actual performance issues or failed drive operations.

More minor occasional soft ticks may just indicate normal HDD head alignment calibration movements. But frequent loud ticks almost certainly mean the drive has a mechanical defect requiring replacement.

It is recommended to immediately backup data and replace the drive before failure occurs if concerning ticks arise. The ticks likely indicate instability that precedes more serious failure down the road.

Conclusion

Hearing your hard drive suddenly start clicking or ticking can be worrying. In most cases, it indicates mechanical issues with the read/write heads and rotational parts that will get progressively worse over time.

Continuing to use a clicking or ticking hard drive is risky since failure could occur at any moment resulting in catastrophic data loss. The only options are professional data recovery, and then replacement of the faulty drive.

To avoid clicks and ticks, go with reliable drive models, handle your computer gently, keep the HDD cool and dust-free, and follow other best practices. But ultimately hard drives are mechanical devices subject to wear, meaning clicks and failure are inevitable over time.
