Why Do Hard Drives Lose Data?

KAB Computer Services classify hard drive data loss in two categories:

• Logical failure - the hard drive is in working order but some files or data cannot be accessed for logical reasons such as a lost partition or accidental reformatting.
• Mechanical failure - the hard drive is not functioning. The most common causes are head crashes and motor failures.

What Causes Hard Drive Failure?

The list of incidents causing hard drives to fail and lose data is not limited, but some of the main causes that we recover from include: power surges, overwriting, physical damages, natural disasters, and viruses.
