The scenario is typically one such as this; John (fictional character) is going about his day-to-day life, minding his own business, working away on his computer when suddenly, it crashes. Maybe it was a virus or the motherboard that overheated. Or maybe John dropped his laptop or some other damage occurred which, regardless of what, he now needs to recover the information on his hard drive.
What is Data Recovery?
Wikipedia describes data recovery as “...the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally”. To put it more plainly, some something has occurred which resulted in a person not being able to access their electronic device and they now need a way to recover their files. Thus, the actual process of data recovery involves using software and/or an alternate computer to recover files from the damaged computer.
Types of Data Recovery Situations
There are only two types of situations, where a person would need to have their electronic information ‘recovered’.
* Internal damage to the device
* External damage to the device
Internal damage refers to programs designed to alter the way the computer works. Commonly known as viruses (which can include adware and malware), the purpose of these programs is to disrupt how a computer normally functions. Given enough time, these programs can change file names, paths, directories, links, computer commands and partially or completely delete items, thus resulting in a ‘crash’.
External damage refers to something physical happening to the device. Exposure to heat or liquids (especially anything with sugar) can result in damage to the circuitry. Impact damage from dropping the device, or it being involved in an accident (such as a car accident), which may damage the memory storage unit (memory card or flash drive or hard drive).
Data Recovery: How Does it Work
Depending on the type of damage to the memory of the electronic device, data recovery can be as simple as plugging into a secondary device. For instance, if one were to drop their digital camera, the camera itself may be ruined, but the memory card may be have suffered no damage at all. In that instance, simply plugging the memory card into another device that could read it may be all that is required to retrieve the data. If there is no damage to the memory unit, then there is no need for data recovery software.
