Hard drive data corruption arises when a system cannot completely write data to a file or the file’s parts become inaccessible. Corrupted files usually become inaccessible and useless, causing further data loss. Data corruption on HDDs can occur for different reasons. Some examples include mechanical component failure, software errors, and electrical events.
Since larger data take up more physical space to store files on a hard drive’s platters, severe data corruption is more likely with larger files than smaller ones. If there are tracking issues on the hard drive or some read/write head problems, corruption may affect multiple files or folders at the same time. Also, poor operating conditions of the drive frequently cause physical hard drive issues that can lead to corruption. However, all hard disk drives eventually fail due to wear and tear.
Common Causes of HDD Data Corruption Include:
- Virus and Malware Damage
- Bad Sectors
- Read/Write Head Issues
- Sudden Power Failures During File Processes
- Software Failures
- Malfunctioning Antivirus Software
Data Corruption Symptoms
Usually, Blue Screen of Death (BSOD) errors, system shutdowns, and program crashes are indicators of file corruption errors. Such errors prevent hard drives from systematic work. Thus, the device can no longer complete a requested process, resulting in localized file damage.
When files are corrupted, their parent programs frequently refuse to open them. Common error messages you may face include “File format not recognized” and “{File name} is not recognized.” Files and folders may also completely disappear.
Additionally, when refusing to execute specific commands, your PC’s or laptop’s operating system may refer to bad sectors.
Some common symptoms of hard drive data corruption include:
- Drive inaccessibility
- Slow HDD performance
- Missing files
- Blue screen of death (BSoD)
Apart from the issues listed above, sometimes physical hard drive issues can cause data corruption as well. Thus, you may notice clicking sounds, excessive vibration, and other similar symptoms with your external hard drive. If you recognize symptoms of a physical or logical failure, we recommend shutting down your hard disk immediately.
Continuing to use the damaged device and writing new data to the drive with file corruption issues can cause complete data loss. The data can get overwritten and, thus, decrease the chances of successful data repair.
How to Fix a Corrupted External Hard Drive
When an external hard drive becomes corrupted and unreadable, it can cause a great deal of stress and anxiety for the user. In an attempt to resolve the issue, many people turn to tools like Chkdsk and Scandisk, hoping to identify and fix bad sectors on the drive’s platters. While these tools may be helpful in some cases, they can also cause further media damage, ultimately exacerbating the problem.
Instead of relying on these tools, it may be more effective to use data recovery programs that specialize in treating corruption. These utilities can be helpful in recovering lost data, but it’s important to keep in mind that no software can fix mechanical or physical hard drive damage. In fact, using such software on a damaged drive can even cause more harm than good, potentially damaging the magnetic material that stores your files.
If your external hard drive is corrupted and unreadable, it’s crucial to avoid running any software that could cause more damage. Instead, it is recommended to keep the drive powered off and seek the assistance of a professional data recovery company.

How to Fix a Corrupted External Hard Drive Without Formatting
If you suspect that your external hard drive is corrupted, it is essential to act quickly to prevent further damage or data loss. One option to try before formatting your drive is to use a data recovery software tool. These tools are designed to scan your drive for corrupted files and recover them. While data recovery software can be effective, it is essential to use a reputable and reliable tool, as using an unreliable tool can cause more harm than good.
Another option to try is to use the chkdsk command in Windows or the fsck command in macOS, which can help repair errors on the drive. However, it is important to note that these commands can potentially cause data loss, so it is crucial to back up your important files before attempting any repairs. If these methods fail, it may be necessary to seek professional data recovery services to recover your lost data.
Although you cannot access your data, it is still stored on that non-bootable hard drive. However, you first need to have the issue resolved to access your data.

Frequently Asked Questions
What does it mean when an external hard drive is "corrupted"?
When an external hard drive is corrupted, it means that the file system or data on the drive has become damaged or inaccessible. This can result in data loss or an inability to use the drive properly.
How do external hard drives become corrupted?
Improper Ejection: Disconnecting the drive without safely ejecting it from the computer can lead to corruption as it may still be in use.
Power Surges: Sudden power surges or electrical issues can damage the drive’s circuitry and cause corruption.
Physical Damage: Physical shocks, drops, or exposure to extreme temperatures can physically damage the drive and lead to data corruption.
File System Errors: File system errors can develop over time due to improper usage or software issues, causing the drive to become corrupt.
Virus or Malware: Infections from viruses or malware can target the drive’s files or file system, leading to corruption.
Bad Sectors: The drive may develop bad sectors over time, making data stored in those areas inaccessible.
Can I recover data from a corrupted external hard drive?
