Why do hard drives get corrupted?:

Physical failure: the hard drive may be physically damaged by heat, moisture, or electric shock. These physical damages may cause serious damage to the hard drive, resulting in hard drive failure. Most of the time, due to the impurities accumulated in its filter, the fan cannot provide sufficient cooling for the hard drive, which will cause thermal damage to the hard drive. Water overflow on the hard drive cam can cause moisture damage, while falling laptop can cause hard drive damage.

Logical failure: logical failure is usually related to software problems, not physical damage. Viruses, file system corruption and human errors may cause logical corruption. The common blue screen error problem is often caused by the logic damage of the hard drive.

Mechanical failure: hard drive contains some mechanical components, such as optical disc and read-write head. Over time, these mechanical parts will age and cause damage to the hard drive.

How to distinguish the causes of hard drive crashes?

Physical damage and logical damage can be distinguished according to the symptoms of hard drive damage. If the hard drive has obvious symptoms of physical damage or is damaged in case of overheating, it is obvious that the physical damage causes the hard drive to crash. In addition, if the hard drive stops working immediately after being impacted or overflowed, it is also a physical failure. The hard drive with logical crash will have symptoms such as low system performance, accidental data loss and disk error.


Hard drive damage is unpredictable, but it can be prevented by maintaining and optimizing the health of the drive. The best way to avoid data loss due to hard drive damage is to back up regularly. For physical hard drive damage, it is recommended to seek professional help to recover the data.
