1 . Analysis of the causes of hard drive data loss
* Data loss due to hard drive failure : Missed circuit , bad sectors , dead body , mechanical errors ( corrupted reader , reader error , scratched discs ... )
- In case of damaged vessels : usually caused by fire
- The case of bad sectors , dead body , engine error : possibly due to the longevity of hard drives , due to unstable power source plug , or drop by bumps , resulting in damage to perfection, ... hard drive .
* Data loss caused by the user or by the virus : It's possible that you accidentally deleted , ghost , wrong format or wanton destruction . Because the virus hides data .
2 . Recovery plan for each case of hard drive data loss
a. For the case of data loss due to deletion , ghost , or viral wrong format : The rescue deleted data fast and simple , low cost if you do not handle anything on the drive.
Note: This case will become more difficult when running recovery software and copy the data subject . Running the free software database on the internet usually do not get back 100 % of the data or file recovery can be faulty . Therefore, the data structure will be broken causing the older restoring more difficult . If you accidentally copy the data subject is not able to recover .
b . In the hard disk bad sectors , dead body , engine error : The logic to save the data in this case is not simple , require people with expertise in the field of research is the data but actually capacity , equipment and machinery must be dedicated can retrieve data .
Hopefully you will have options to restore optimal for the case of data loss on your hard drive . Avoid handling yourself is dangerous for other important data .
