Causes of Hard Drive Failure

Not always are severe mechanical damages (e.g. water damage or head crash, fall) responsible for defective hard drives. Often, so-called logical causes are behind impending data loss. If you stay calm and take the right steps, your data can be successfully recovered from almost all storage media and in most cases.

Common Causes of Defective Storage Devices and Data Loss

Severe mechanical damage (e.g. water damage, head crash, drop) is not always to blame for defective hard drives. Frequently, so-called logical causes are behind impending data loss. If you stay calm and take the right steps, your data can be successfully recovered / rescued from almost all storage devices and in most cases. Watch for the symptoms of defective hard drives to act in time.

Physical Causes

Physical defects in hard drives always refer to affected components. For example, a laptop or external HDD drop (head crash) can cause the read/write head to touch the platter surface. Our specialists for HDD data recovery can help in most cases.

Mechanical Defects

Logical Defects

A logical defect occurs when digital causes such as premature disconnection of an external hard drive or a computer virus are responsible for data loss. The intentional or unintentional deletion / overwriting of files also falls under logical errors.

Software Errors

First Steps for a Defective Hard Drive

Turn off the external storage device or the computer (internal hard drive) and disconnect it from the power supply to avoid power surges and overheating. Also avoid strong temperature fluctuations, vibrations, and do-it-yourself data recovery measures with free tools from the internet. Instead, contact a professional data recovery specialist on-site.
