Recover Lost Data in 3 Steps




-A disk drive (HDD) is a data storage device used for storing and retrieving digital information using rapidly rotating discs (platters) coated with magnetic material. An HDD retains its data even when powered off. Data is read in a very random-access manner, meaning individual blocks of information may be stored or retrieved in almost any order instead of sequentially. An HDD is made up of several rigid ("hard") rapidly rotating discs (platters) with magnetic heads arranged on the moving actuator arm you just read and write data to the surfaces.
Introduced by IBM in 1956, HDDs had become the dominant secondary storage device for general purpose computers through the early 1960s. Continuously improved, HDDs have maintained this situation into the modern era of servers and private computers. More than 200 companies have produced HDD units, though most up to date units are produced by Seagate, Toshiba and Western Digital. Worldwide revenues for HDDs shipments are required to succeed in $33 billion in 2013, a decrease of about 12% from $37.8 billion in 2012.
The primary characteristics of an HDD are its capacity and gratifaction. Capacity is specified in unit prefixes corresponding to powers of 1000: a 1-terabyte (TB) drive features a capacity of merely one,000 gigabytes (GB; where 1 gigabyte = 1 billion bytes). Typically, some of the HDD's capacity is unavailable on the user because it is used by the file system and also the computer operating system, and perhaps inbuilt redundancy for error correction and recovery. Performance is specified by the time to advance the heads to a file (Average Access Time) plus the time it takes for that file to go under its head (average latency, a function of the physical rotational speed in revolutions each and every minute) and the speed at which the file is transmitted (data rate).
The two most typical form factors for modern HDDs are 3.5-inch in personal computers and two.5-inch in laptops. HDDs are connected to systems by standard interface cables for example SATA (Serial ATA), USB or SAS (Serial attached SCSI) cables.
