Today the world revolves around the computer. From homes and offices to schools, airports and hospitals, computers have become an integral and indispensable part of our daily lives.
One of the foremost uses of computers is data storage. Data stored on the computer resides on a physical memory disk known as the hard drive that is a layer of magnetic disks. As people become increasingly dependent on computers, the risk of data loss also surfaces.
Hard drive crashes are a common occurrence. They are classified into two categories — logical and physical. While the logical aspect deals with failure of the file system and software, the physical aspect is related to some sort of electrical or shock damage to the disk. However, modern technology allows us to recover up to 80% of the lost
If the hard drive has suffered physical failure, proper electronic knowledge and equipment is a must. A soldering iron might prove useful when working on a damaged circuit board. Advanced tools such as magnetometers may also be used to physically extract lost bits from the magnetic media. These bits are used to rebuild a disk image.
In addition to the hands-on equipment required, certain other precautions must be taken. The hard drive, when removed, should be wrapped in anti-static material. The drive should be well cushioned to prevent further damage. Finally, the
