The moment you plug your external hard drive in, a window opens stating that it can’t be read, or that it’s inaccessible. You might even receive a window that suggests formatting it. Regardless, something has happened that’s now preventing you from accessing your files.

In these situations, you have to be strategic in what you do. Making changes could worsen the situation if you’re unsure of what you’re doing. In this article, we’ll discuss what could have caused this to happen and how to recover your external hard drive without formatting it.

👀

As with any data loss situation, you should stop using the drive immediately. Continued use of the affected drive may result in new data overwriting your lost files. Only use the drive once you’re prepared to implement the fixes outlined in this article. Click here to jump straight to the recovery guide.

Reasons Behind Faulty External Hard Drives

Hard drives are far from perfect. Their proneness to data-related issues worsens as they age. Let’s take a look at a few common reasons why your external hard drive has decided to stop working:

  • 🦠 Virus attack – Viruses can be created to attack your hard drives. This includes external hard drives that are connected at the time of a virus attack.
  • 😷 Corruption – If a hard drive is removed during a write operation, there’s a chance that the hard drive, data included, will become corrupted. Corrupted data is inaccessible and corrupted drives have problems being recognized.
  • 🔧 Driver issue – Drivers are what allow our computer’s hardware and operating system to communicate with each other. If they’re outdated or corrupted, this could result in a breakdown in communication.
  • 💥 Physical damage – Anything that results in physical damage to the hard drive. Water damage, drops, and faulty cables, etc. Physical damage is harder to recover data from if the drive isn’t being recognized, and often requires an inspection from a professional.
  • 💻 Incompatibility – It’s possible that the hard drive won’t work with the computer or operating system you’re attempting to use it with due to hardware or file system compatibility issues.
  • Bad sectors – Possibly caused by physical or logical failures, bad sectors can degrade the performance of the drive, or they can even make files inaccessible.

Any one of the above problems can prevent access to the drive. Let’s move onto how you can recover an external hard disk without formatting.

How to Take Care of Your Data

Of course, while data recovery is a lifesaver in many situations, actively taking care of your data ensures you’re less likely to lose data in situations like this one.

💾 Make regular backups

You won’t ever have to worry about recovering your data if you always have a copy on hand. Making regular backups may sound tiresome, but it’s the best way to ensure your data is safe.

🦺 Eject drives safely

Unplugging your drive without ejecting it safely can interrupt write operations. If this happens, there’s a chance your data, and perhaps your entire drive will become corrupted. To avoid this, make sure to eject your drive safely before unplugging it.

💼 Store drives properly

Drives, especially hard drives, are very susceptible to physical damage. While some manufacturers invest in sturdy housings for the drive, it’s still only one layer of protection. Consider buying an external hard drive case for your drive to live in.
