A hard disk functions as a long-term memory of a computer. When you save data or install programs on your computer, the information is written onto the hard disk that records and stores that information in return. The hard disk is housed inside the hard drive, which reads and writes data to the disk.
A hard disk can be classified into two categories pertaining to its utility. An internal hard drive is the primary storage device located inside the computer system. It can capacitate pre-installed software applications, the operating system and other files. Many desktops have several internal hard drives that allow them to provide greater data storage.
The other one is an external hard disk that is a separate device which needs to be connected to the USB port of the CPU while using. Many new-age hard disks can communicate with the system unit wirelessly.
A hard disk is touted as a vital part of the computer owing to its several characteristics. It provides large storage capacity ranging from 160 GB to 2TB and more. A primary source to store crucial information, a hard disk functions much faster than a floppy disk. The data stored in a hard disk is much more reliable and safer than stored on a floppy.
Most often a hard disk drive malfunctions and the stored information cannot be accessed when it is used without a properly configured computer.
Usually hard disk failure occurs primarily under two situations. One is during normal regular usage and second accidental exposure to fire, water or high magnetic fields through sharp intact or environmental hazards.
Hard drives may also be rendered inoperable through data corruption, disruption or destruction of the hard drive's master boot record, or through malware deliberately destroying the disk's contents.
A laymen approach to fixing hard disk errors is carried out by scanning your computer system through installing and running authentic anti-virus software. Another way is to make use of data recovery tool.
Such methods might resolve basic hard drive errors but are incompetent to handle bigger and serious hard disk error issues.
