Data loss - Hardware reason

Sometimes data loss is because of hardware, such as bad sector in hard disk, power cut, head damage, circuit panel problem, etc.

When your hardware has some problems, you probably will find: the speed of hardware become slow; you cannot operate successfully; you cannot read data, etc, which are most often physical bad track failures.

Correspondingly, data recovery in hardware fix is considered as hard recovery, such as memory medium damage, track damage, hard disk scrape, head damage, electric machinery damage, chip burnout and so on.

The most distinct feature or difference between soft recovery and hard recovery is whether the memory medium itself can be normally accessed by fixing or replacing parts.
