There are different types of storage devices available, and we choose one or the other to store our valuable data as per our convenience. Still, hard disk remains the primary storage media in a home or office computer / laptop by most of the users. We store large amount of our valuable data in the computer hard drive on a daily basis, and moreover, whether it is an internal hard disk or an external one, we use hard drives as a permanent storage and that to for a longer span of time . Along with their much usage and exposure to various types of data, they are highly vulnerable to data loss. However, with modern day hard disk recovery techniques, recovery from your hard drive is quite possible these days.
Some of the common cases of data loss in a hard drive:
* The system fails to boot or showing the BOD (Blue Screen Of Death).
* The system failed to detect the hard drive.
* Damage to the chips or connectors.
* The hard drive is making some unusual clicking or grinding noise.
* The hard drive remains silent, on powered on.
A hard disk has many physical components, including head, platter, motor, PCB etc. and any problem to these components can cause serious data loss. In brief, any mechanical, electrical or firmware failure to the hard disk due to power surge, file system corruption, accidental deletion of system registry, deadly virus attack, malware intrusion or any other external factor such as flood, fire, heat, magnetic waves etc can lead to data loss or inaccessibility.
In all the above situations of data loss, either by temptation to experiment or in haste, users start running untrusted tools / software, which can further deteriorate the chances of recovery. Till, they realize their mistake, it is already late and their data goes to a level beyond recovery. One thing should be kept in mind that the data in the hard drive is never permanently lost and can be recovered until it is being overwritten by some other data. Here, once you witness any instance of data loss / inaccessibility with your hard drive, let the hard disk recovery professionals to do the hdd recovery, as hard disk recovery is a carefully executed systematic process and the experts know it better. Moreover, the hard disk should never be opened in an ordinary environment and only inside CLASS 100 Clean Room, as in ordinary environment, dust particles can go inside the head and the platter, damaging the platter beyond recovery.
Note: CLASS 100 Clean Room is a controlled environment, where there are less than 100 dust particles (below the size 0.5 microns) in comparison to some thousands in an ordinary environment.
