There are several reasons for a typical hard drive crash: Clicking noises from the hard disk are a clear indication of mechanical damage. With time, these mechanical components get deteriorated and fail to cause crashed hard drives. Mechanical Failure: The hard drive contains some mechanical components like the disc and the read-write head. The appearance of the famous blue screen of death is a clear indication of logical damage to a hard drive. Logical damage can be caused by viruses, corrupted files, and human error. Logical Failure: it is software related and does not have anything to do with physical damage. Water spillage on the hard drive can cause damage due to moisture while dropping the laptop can cause shock damage to the hard drive. Most of the time, the inability of the fan to provide enough cooling to the hard drive owing to accumulated impurities in its filter causes heat damage to the hard drive. All of these can cause serious damage to a hard drive causing it to fail. Physical Failure: A hard drive can get physically damaged by heat, moisture, or shock.
