Natural Disasters: As we all know, man can never control nature. This means if disasters occur naturally like floods, tornadoes or earthquakes, then the data within ones laptop is bound to be destroyed and get lost.
Human mishandling, carelessness and motive: Human errors can come in these forms. They motive of human can be either intentional or non-intentional. Non-intentional errors may include accidental erasure, accidental dropping of the laptop and also sometimes forgetting to backup data. Human beings are not perfect and thus are bound to carry out many erroneous deeds. Some intentional human errors are mainly computer crimes like hacking into one’s laptop and deleting some data. Stealing is also considered a human error because the motive is wrong. Another way human beings may cause you to lose data in you laptop is by introducing a virus to your laptop. That’s evil, but believe it or not, people actually do it. Try your best and keep your laptop safe!
Hardware and/or System failure: Some the hardware components of ones laptop are vital for data storage, especially the hard drive. If the hard drive fails or crashes, information is unable to be read by the user. The user may think the data is lost but it can be recovered. For example, if you drop your laptop and the hard drive still remains intact, chances are high that all your information will be recovered. Otherwise, if it is damaged, some of the information may be recovered.
Also, if the operating system of a laptop fails to work, there is a possibility data will be lost. The operating system is the basic platform on which all other software and other utilities of the laptop are built on. It is also the basic component that enables data retrieval hence, its failure leads to data loss.
Virus Infection: Viruses are programs that are designed to corrupt or interfere with the normal operations of a computer system and even cause destruction of files. The destructive ones attach themselves to certain files and ensure all the data within is completely destroyed. The viruses may also cause one of the above problems i.e. system failure. They cause system file corruption and when read, many error messages are produced.
