What Is Hard Disk Recovery
Almost everyone who has ever used a computer has erased a file that they later wanted to bring back. The less fortunate may have also had the experience of losing an entire hard drive. Luckily, hard disk recovery allows for lost data to be recovered.
Hard disk recovery is possible because of data remanence, which means that some data continues to exist on the hard drive even after it has been deleted. While data remanence is beneficial to hard disk recovery, there is also a downside; that is, data remanence is one of the most convenient tools used in cyber-espionage. That's why computer security experts tell you that simply erasing a file doesn't always completely delete it.
A hard drive contains a series of hard disks that rotate rapidly. These disks are coated with magnetic particles, similar to a magnetic recording tape. The hard disk is actually very durable, and good maintenance will ensure long life. If it is not exposed to extreme temperatures, and does not suffer any physical damage, it can easily last for ten years. However, hard disks do have several moving parts, and can become damaged or wear out.
Hard disk recovery reconstructs lost files, regardless of whether they were deleted accidentally or are inaccessible due to a crashed hard drive. In some circumstances, the hard disk may become inaccessible because of a hardware problem. The actuator arm, a small mechanical arm that moves back and forth across the disk, may have suffered a mechanical error. In this event, the data is not lost at all, but is just inaccessible due to this mechanical problem. Similarly, the circuit board may develop flaws, which may make the hard disk inoperable. If there are strange noises, or no noise at all, the cause is likely mechanical, and a technician will have to disassemble the hard drive to repair the problem. In some cases, the mechanical problem may cause the drive itself to become damaged, which may directly affect the data. Alternatively, data loss may occur due to a software problem.
Taking a little preventive action can help prevent the need for hard disk recovery. When files become fragmented, they are stored in multiple clusters on the hard drive, which makes the computer take more time to read it. A drive with a lot of fragmentation will be harder to recover in the event of a crash. Therefore, it is recommended to regularly defrag your hard drive.
