Optimal conditions for hard drives are between 20 and 25 degrees Celsius. Thus, overheating causes frequent adjustments to the crystal oscillator clock. And it will mess up the inner workings as well. Therefore, you should make appropriate efforts to cool your hard drive and keep it safe from heat.

Physical Damage

Damage to the hard drive’s casing is a leading source of faulty sectors. Causes include rough treatment, falls, and high temperatures. A disk’s magnetic field is so weak that even a scratch might render the damaged area useless for storing information. Bad sectors are when the read/write heads are misaligned or damaged due to impact from accidents or rough treatment.

Hard Drive Age

Bad sectors can emerge on hard drives due to normal wear and tear over time. The magnetic coating on the platters is worn away over time due to the platters’ constant spinning and the read/write heads’ constant motion.

The heads’ ability to read and write data reliably degrades due to this wear and tear, leading to inaccuracies and the eventual appearance of faulty sectors. Type cmd in the Run window that appears after pressing Windows + R. Enter “wmic” and hit the enter key. Press Enter after typing “wmic diskdrive get status” to inspect the disk’s current condition.

Software and Malware Issues

Human error can also cause bad sectors in software or malicious software. Sectors can become bad when misallocated or corrupted due to issues with disc management software, operating system bugs, or poorly conducted disc operations like formatting or partitioning.

Malware like ransomware and disk-wiping viruses can cause physical or logical damage to the hard drive, resulting in the appearance of bad sectors. You can start protection updates by typing virus & threat protection at the search bar. After that, click on it. After that, go to virus & threat protection updates and check for updates.

Manufacturing Defects

Sometimes faulty sectors appear on a hard drive because of a manufacturing flaw. Discs with these problems may have uneven surfaces, read/write heads that aren’t aligned, or malfunctioning electrical components. Bad sectors are more likely to occur on a hard disc, with manufacturing faults undermining the drive’s reliability.

Electrical Issues and Power Surges

Power surges, voltage changes, or sudden power outages can cause bad sectors on hard drives. A power outage during data writing might cause faulty sectors due to incomplete or incorrect data. The magnetic coating on the disc can be damaged by the read/write heads making accidental contact with it if there is an electrical problem.

Shock or Sudden Impact

Hard drives are vulnerable to mechanical failure if they sustain sudden impact or physical shock, such as when the device is dropped or accidentally smacked. Because of the force of the hit, the read/write heads may become unaligned or displaced, the platters may be broken, or other internal components may fail. The afflicted sections of the disc may develop faulty sectors due to the physical impact.

What are the Symptoms of Bad Sectors on a Hard Drive?

Errors when opening or saving files, sluggish operation, frequent system freezes, and crashes are all signs of bad sectors on a hard drive. The hard drive may be making odd noises in conjunction with these problems. To avoid further hardware failure, bad sectors must be dealt with ASAP.

Your computer’s performance and security are at risk when a hard disk has bad sectors. Understanding the warning signs of failing sectors is critical for intervening quickly to limit losses. In this section, we’ll review the symptoms typically associated with faulty sectors on a hard disk, so you can identify the problem and fix it before it worsens.
