Data loss is one of the biggest concerns for everyone who creates, modify or enter data into a PC.
Data Loss occurs when you no longer have access to the required data by normal means, generally caused by corruption of file system, data media damage, hard disk crash or virus attack ect.. It can impact anyone doing routine data entry, including businesses or individuals. Depending on the Type of data loss that occurs, it may be possible to recover most, if not all, of the data using various data recovery methods.
Types Of Data Loss
One of the biggest causes of data loss is human error. Human error can consist of accidentally formatting a computer hard drive, unknowingly deleting a file or folder and damage to the computer. Working with computers requires knowing a computer's basic operation so that preventable errors do not happen.
File Corruption occurs due to a defect or bug in the software used to create and manipulate the file in question.
Often, this is a temporary problem that will occur once, then disappear forever. At other times, the bug may be the result of an infiltration by a virus or other foreign software that disrupts the function of the program. When the user attempts to open the corrupted file, the system may lock up or provide a message identifying a problem with the file.
There are a number of hardware problems that can cause your drive to Malfunction here are a few :
Head Crash : is a hard-disk failure that occurs when the read/write heads of a hard-disk comes in contact with the rotating platter, It's most commonly caused by a sudden severe motion of the disk, for example the jolt caused by dropping a laptop on the ground while it is operating.
Bad Sectors : A hard drive that has bad sectors is unable to write data to that specific area, If data was on a sector that can no longer be accessed.
Disk Controller Failure : Disk controller is a circuit that works as an intermediate between the CPU and hard drive. When the disk controller gets damaged or it fails, hard drive become inaccessible, undetectable in BIOS and renders the system un-bootable.
Cpu Failure : CPU overheating due to case fans not working
These failures will can cause a significant amount of data loss!!!.
