“Data” is a raw material stores in a format of rows and columns which can be processed later on to get information. Data loss is situation where these data stored in the hard drive is lost or becomes inaccessible. Loss of data is most effective way of destroying any business or individual. Though of loosing data even on temporary basis give nightmare to businessmen. Let us look at the ways in which we loose our data. Hard Drive Failure Head crashes are the most common type of failure which occurs in hard drive. There are more than 44% of failures which occur due to hard drive failure. Head of the hard drive is most delicate piece of equipment. Hard disk platter in 1 second rotates 150 times. The head moves above this platter with only sub micro distance between them. Any disruption causing can cause head crash which leads to hard drive failure. Even dust particles which get traps between platter and head can cause severe damaged to the head making the hard drive inaccessible.Electro-Mechanical Failure This type of failure is also a physical failure where the circuit board of the hard drive gets affected. Electrical failure is because by electro- static discharge which damages the circuit board located at the bottom of the drive. Due to power surge and lightening also causes electrical failure. Software Malfunction There are times data loss occurs due to software malfunction, software on which we are working doesn’t function properly as a result the programs freeze and we are unable to save the data causing the data. Sometimes some software may also corrupt the operating system which leads to data loss.Data recovery software helps in recovering lost data.Viruses AttackAn operating system failure can also cause by viruses. Some viruses along with the other program or through the internet get into our hard drive. These viruses get themselves loaded in the operating system causing system file to corrupt thus we run a data loss situation. Natural catastropheNatural disaster like earthquake, flood, fire, and lighting are the some ways in which we also experience a data loss. Flood cause extensive damage to the hard drive as large amount of moisture damage the electronic circuit by hastening the oxidation process. Data Recovery Service company are capable of recovering data any type loss situations.
