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.
Also, if the operating system of a laptop fails to work, there is a possibility data will be lost. This is because the operating system is the basic platform on which all other software and other utilities run on. It is also the basic component that enables data retrieval hence, its failure leads to data loss.
Human Error: There are many forms of human errors. They can be classified into intentional and non-intentional human errors. 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. Thus, try and make your laptop as personal as possible. http://smartwebsiteideas.com/
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.
Computer Viruses: 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, forcing you to desperately seek data recovery solutions.
