External hard drives are a convenient way to store large amounts of data, from family photos and important documents to music and movies. However, when they suddenly stop working, it can be a frustrating experience. In this blog post, our team will explore why an external hard drive may not work, some risk-free diagnostic methods to identify the problem, and data recovery options for external drives.

Reasons Why USB External Hard Drives not Working

  • Physical Damage. External hard drives are prone to physical damage as they are often transported around. Dropping or banging the hard drive can cause mechanical issues that prevent it from working properly.
  • Power Issues. If the external hard drive is not getting enough power, it may be unable to spin up or operate. This can happen if the USB cable is damaged, the power source is inadequate, or the USB port on the computer is faulty.
  • File System Corruption. The file system organizes and manages the data stored on the hard drive. It can prevent the operating system from accessing the files and folders on the hard drive if it becomes corrupted.
  • Bad Sectors. Bad sectors are areas on the hard drive that are damaged or corrupted. They can occur due to physical damage or other factors and can prevent the hard drive from reading or writing data in that area.
  • Malware or Virus Infection. Malware or virus infection can cause damage to the hard drive and corrupt files, making them inaccessible.

Risk-Free Diagnostic Methods When External HDD not Working

Before attempting any data recovery methods, diagnosing the problem with your external hard drive is important. Here are some risk-free diagnostic techniques to identify the issue:


Check the Cables and Power Source

Check the USB cable for any signs of damage, such as fraying or breakage. Also, make sure the power source is adequate, and the USB port on your computer is working correctly.


Try a Different Computer

Connect the drive to a different Windows PC or iMac to see if it works. If it does, the problem may be with your computer rather than the hard drive.


Use Disk Utility

Disk Utility is a built-in tool on computers that can diagnose and fix the external drives. Connect the external hard drive to your PC and open Disk Utility. Select the external hard drive and click First Aid to scan for and repair errors.



CHKDSK is a command-line tool in Windows that can diagnose and repair issues with hard drives. Connect the external hard drive to your Windows computer, open Command Prompt, and type “chkdsk X: /f” (replace X with the drive letter of the external hard drive) and press Enter. This will scan and repair any errors on the hard drive.

What not to Do When the External Disk Drive is Not Working?

When your external disk drive stops working, it can be a frustrating experience. You may be tempted to try and fix the issue yourself or use recovery software to recover lost data. However, these steps can be risky and may cause further damage to your device.

Using Recovery Software

One of the first steps people take when encountering a problem with their external hard drives is to use recovery software. While recovery software can help recover lost or deleted files, it can also cause more harm than good. 

Recovery software works by scanning the disk for data and attempting to retrieve any recoverable data. However, if the disk has physical damage, trying to use recovery software can cause further damage to the disk, making data recovery more difficult and sometimes impossible.

Additionally, some recovery software can be malware or spyware that can damage your computer and put your data at risk. If you choose to use recovery software, it is important to choose reputable and trustworthy software from a reliable source. Even then, recovery software should be used cautiously and only as a last resort.

Trying to Repair the Device Yourself

Another common mistake people make when their external hard drive stops working is attempting to repair the device themselves. This can be tempting, especially if you are familiar with technology and have some knowledge of how to fix things. However, attempting to repair the device yourself can cause more damage to the disk and make data recovery more difficult and sometimes impossible.

There are several components inside the external hard drive that can be damaged, including the read/write head, the platters, the motor, and the circuit board. Attempting to repair any of these components yourself can be risky and potentially worsen the problem.

If your external hard drive stops working, the best course of action is to power down the device and send it to professional data recovery services like PITS. Data recovery service providers have the expertise and equipment necessary to diagnose and repair a wide range of issues with external hard drives.
