When the file system on your external drive is corrupted, it can affect the drive. Other reasons include bad sectors on the hard drive, physical damage, malware, etc.
I’ll show you what to do if the hard drive is corrupted.
Let’s begin.
Signs of a Corrupted External Hard Drive
Most of the common signs of corrupted hard drives I’ve experienced are as follows:
- Cannot access files or folders. If you can’t access your files or directories, your external hard drive may be corrupted. When you try to open the files or folders, it shows error messages or can’t read the contents.
- Slow performance. Another sign of a corrupted external hard drive is when your PC slows down, freezes often, or experiences a blue screen of death. I recommend backing up your data in case of a hardware failure.
- Missing files or data loss. Corrupted external hard drives can cause data loss or file corruption. Files could suddenly disappear or become unable to open properly, resulting in potential data loss.
- Unusual sounds. Clicking, grinding, or whirring noises may occasionally come from an external hard disk that has sustained physical damage. These noises can be signs of a mechanical malfunction, which could cause data loss or corruption.
This means that before being retired or replaced, most hard drives used in data centers have a lifespan of almost six years, which is quite good.
So, if your external drive gets corrupted after a few years, you might want to check what’s missing in maintenance. ”
Why Does an External Hard Drive Get Corrupted?
Over the years, as a user and an engineer, I’ve realized that the causes of most external hard drives getting corrupted are how users manage their drives, malware attacks, bad sectors, or software failures.
Let’s briefly go through them:
1. Improper management of hard drives
Any device can be damaged if it’s misused. If a hard drive isn’t ejected properly, its lifespan can be significantly shortened as it becomes more corruptible.
You can also corrupt your hard drive if you use it under extreme heat conditions or unexpected power supply outages.

2. Virus or malware infections
External hard drives are vulnerable to viruses or malware infections, especially if used on several computers or linked to devices with insufficient protection.
Malware or viruses can corrupt files and the file system, making a drive unusable.

3. Bad sectors
Sometimes, your hard disk may show several bad sectors. These are regions of an external hard drive that, after repeated use, lose their functionality and may become unreadable.
Bad sectors also signal that you might need to format or replace your drive immediately.
4. Read/write mechanism issues
A traditional hard drive uses a spinning disk mechanism to write data. Your device’s read/write action is made possible by revolving platters fixed to an arm.
That said, hard drive corruption can be caused by normal wear and tear of or any external impact on mechanical HDD parts.

5. Software failures
Software errors can corrupt a healthy hard disk. While certain flaws might only impact a few, severe situations can lead to your external HDD’s file system becoming faulty.
This problem can be challenging to resolve and result in permanent data loss.

Tips to Prevent External Hard Drive Corruption
Even though it’s good to know how to fix a corrupted external hard drive, it’s best to prevent the problem in the first place.
Here are some tips to keep in mind:
1. Perform a disk clean and optimize your system regularly
Delete unnecessary and large files, junk files, and browser and system cache files that take up valuable disk space to prevent the computer from running slowly.
You can also perform a disk cleanup to improve your hard drive’s performance.
Also, the longer you use your computer in a stationary area, the more dust and debris will gather. This increases the risk of an overheated and malfunctioning hard drive.
If you want to clean it yourself, a cotton bud works well for the interior sections, and a little piece of cotton rag dipped in alcohol can be used to wipe its exterior.

2. Use the sleep and power-saving modes
Regardless of your brand, the more you use your drive, the shorter its lifespan will be. So, when not in use, turn off the hard disk.
Also, try to use the power-saving and sleep modes on your computer when it’s not in use to prevent it from running routine maintenance operations, such as defragmenting, checking for Windows updates, engaging in third-party activities, etc.
3. Use antivirus or anti-malware software
To protect your data from viruses and malware that may corrupt it, use reputable antivirus or anti-malware software like Auslogics Anti-Malware.
You can also use other free, like Windows Security, or premium software options.
