Hard Disk Recovery

Data loss may occur in computers at any time and there are many reasons for computer data loss. Generally, all factors can be divided into two types: physical faults and logical faults. Then what are physical faults and logical faults. We'll introduce them briefly.

• Physical faults:
Physical faults are related to hardware damage in disks and they may cause that hard disk run abnormally. The detailed reasons are following.
1. Circuit failure: disk circuit board burning up or control chip on disk circuit board being damaged makes that disk can not work normally and data can not be read.
2. Firmware damage: Firmware is hardware programs in charge of normal operating of a disk. If it is damaged, the disk can not continue to operate.
3. Head and electrical machine failures: This kind of fault also results in data read failure, namely data loss occurring.
4. Platter damage: Platter is the carrier of data and data loss will take place if it is damaged.


• Logical faults:

Logical faults are related to file system problems. Disk data read and write are realized via file system. If disk file system fails, we can not find disk data and data loss comes up. Common logical faults are following:
1. Partition Table being lost: We can not read and write data in if Partition Table is lost.
2. Boot Sector failure: Boot Sector defines the most important parameters of disk partitions, so we can not operate on disk data once it fails.
3. File Index or other metadata being damaged: data are distributed on disks according to a certain structure. If this type of structure is destroyed, file integrity is damaged and data will be lost.
4. Deletion and formatting: These are artificial reasons for disk data loss.

There are so many reasons for computer hard disk data loss that we have to pay much attention to data security in daily computer use, or important data may be lost unwittingly. However, if data loss occurs, we should get clear about the reasons first of all before perform hard disk recovery. According to different situations, we are supposed to adopt different solutions. If the problems are caused by physical faults, the only solution is to ask professional data recovery companies for help. They will use special hard disk recovery tools to recover lost data. If it is logical faults that cause data loss accidents, we are advised to use professional hard disk recovery software to recover lost data. And a powerful hard disk recovery tool can be downloaded from the specialized hard disk recovery web http://www.hard-disk-recovery.net/.
