Before advancing to the methods in which we can repair a corrupted hard drive without losing data, it is important to first know how to diagnose a corrupted hard drive.

It automatically becomes inaccessible: Whenever you try accessing the hard drive you get an error message saying the drive is inaccessible. This error message also pops up even when you try accessing files in the drive from shortcuts.

The BSOD (Blue Screen of Death): This infamous occurrence becomes your buddy for the day when the hard drive with your operating system gets corrupted. Experiencing the blue screen of death simply indicates a damaged hard drive.

When you begin to have bad sectors: A bad sector is described as the unusable areas of your hard drive, and the files stored in these areas are prone to corruption as well. The good news is, bad sectors can be identified by analyzing Self-Monitoring, Analysis, and Reporting Technology (Smart).

This is why you must understand the common causes to enable you to determine how to fix corrupted hard drive.

Malware and Virus Attacks: A corrupt file system and severe data loss are the end product of an orchestrated virus and malware attack from an unknown source. Fortunately, there is some reliable anti-virus software to help prevent such attacks same time implementing precautionary measures.

Blocks or Bad Sectors: As earlier mentioned, bad sectors are the unusable areas of a hard drive. They become unusable due to long-term use and can cause a hard drive to become unreadable. Sometimes, a user may receive drive reports of a bad sector and may need to format or replace them immediately.

Software Failure: Software bugs are the primary cause of software failure, and this can be seen with hard drives. However, only a few files may be affected by these software bugs, but it becomes an even stickier situation when your entire file system becomes affected, which can potentially lead to permanent data loss.

Improper use of Drives: When a hard drive is misused, it becomes prone to damage and corruption. Incorrect ejecting of drives and operating under non-suitable conditions are examples of misuse and can lead to corruption.

Manufacture or Firmware Faults: This can sometimes be the reason for a corrupted hard drive, irrespective of how careful a user might be. However, firmware updates are frequently released by manufacturers to resolve such problems. These updates can be gotten from their official websites.

Read/Write Issues: A spinning disk mechanism is what’s used to write data in traditional drives. To facilitate the read-and-write process, this mechanism heavily relies on the rotating platters of the traditional drive. And due to the nature of these rotating platters, they are prone to wear and tear which can also lead to read and write issues, and may even cause corruption of the hard drive.
