How to recover data from a corrupted hard disk?

You can recover data from a hard disk or external hard drive with the top-notch EaseUS Data Recovery Wizard. Moreover, you can also learn the full guide to fix corrupted hard drives without formatting. 

Have you ever come across the problem of a corrupted hard drive? When a hard drive is corrupted, you can no longer use it, although it does show as a disk. 

How Can the Hard Disk Become Corrupted

Some typical reasons for data loss from a crashed hard drive fall into two main categories: logical issues and physical damage. 

🗃️Logical Corruption

File System Corruption: This happens when there is damage to the system that controls data storage and retrieval. Erroneous shutdowns or program crashes may cause this kind of corruption.

Virus Attacks: Malicious software may distort, erase, hide, or alter your data. The good news is that recovering from certain malware infections doesn't often involve much pain.

When you attach an external hard drive to your computer, it appears in the list, but you cannot access it to use the data. In this scenario, you cannot view any files or data on the device. This is frequently caused by logical damage or viral infection.

🛠️Physical Corruption

Overheating: Heat is the most common cause of hard drive corruption. If your CPU fans aren't operating properly, your hard disk will overheat and become corrupted.

Mechanical failure: A broken hard drive can result from dropping, scratching, or shaking the device, rendering it non-functional. It results in physically broken drive components, preventing the dead hard disk from operating normally. Power surges and wetness exposure are other common causes of physical corruption on hard drives.

When your hard disk is physically corrupted, you should seek expert assistance for data recovery. Without experience, attempting a do-it-yourself recovery could also result in irreversible data loss.
