Hard Disk Recovery

Hard disk data may be lost due to many unexpected reasons and they can generally be classified into two types: physical reasons and logical reasons.
Logical faults:
Logical faults are related to file system. Data write and read are realized through file system. And if disk file system is damaged, hard disk data can not be found and data loss problems occur as a result. File system in composed of several elements.
1. Partition Table: if Partition Table is damaged, disk partition or volume can not be identified.
2. Boot Sector or Super Block: they define the most important parameters of disk partition or volume.
3. Index and Meta Data: hard disk data and files are distributed in hard disk in a certain structure. And if this kind of structure is destroyed, integrated files or data will not exist, which means that data are lost.

Physical faults:
Physical faults involve hardware damage of hard disk itself, which make hard disk run abnormally, inaccessible or not store data. Hard disk generally consists of circuit board, firmware, head, platter, electrical machine and so on and each component may fail sometimes.
1. PCB gets burned: if circuit board or chips on circuit are burned, hard disk will not work.
2. Firmware corrupts: firmware is a hardware program that controls the normal run of hard disk. It can be considered as the "brain" of a hard disk, and if it fails, the hard disk fails, too.
3. Head and motor failure: head and electrical motor are mechanical components of a hard disk, located in sealed and dust-free disk body. Head being aged and deformed or electrical motor being burned or stuck will lead hard disk to be useless.
4. Platter scratch: platter is the carrier of data. And bad tracks may be produced in the process of using computer.

Data loss problems resulting from the above reasons have corresponding solutions. As to physical reasons, we can do nothing but resort to professional data recovery companies, which will cost much, so we should go to any length to protect hard disk from physical damages. As to data loss issues caused by logical problems, we can deal with them easily if we are in possession of hard disk recovery software, recovering hard disk data without any difficulty.
