We’ve all done it – deleted files when we didn’t mean to. Whether it’s accidentally dropping them in the Recycle Bin, hitting Delete instead of Save or deleting something in DOS without thinking things through first, we’ve experienced that jaw-dropping realisation that we’ve lost work. And you may have experienced even more horror at a hard-drive crash.

However, it’s very rare that those files are completely deleted for good. Even when something really catastrophic does happen – that is, your hard drive seizes – there are professionals that can work digital miracles on your equipment to resurrect the data.

Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, solid-state drives (SSD), USB flash drive, storage tapes, CDs, DVDs, RAID, and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.

The most common “data recovery” scenario involves an operating system (OS) failure (typically on a single-disk, single-partition, single-OS system), in which case the goal is simply to copy all wanted files to another disk. This can be easily accomplished using a Live CD, many of which provide a means to mount the system drive and backup disks or removable media, and to move the files from the system disk to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.

A hard 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 random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially. An HDD consists of one or more rigid (“hard”) rapidly rotating discs (platters) with magnetic heads arranged on a moving actuator arm to read and write data to the surfaces.

Introduced by IBM in 1956, HDDs became the dominant secondary storage device for general purpose computers by the early 1960s. Continuously improved, HDDs have maintained this position into the modern era of servers and personal computers. More than 200 companies have produced HDD units, though most current units are manufactured by Seagate, Toshiba and Western Digital. Worldwide revenues for HDDs shipments are expected to reach $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 performance. Capacity is specified in unit prefixes corresponding to powers of 1000: a 1-terabyte (TB) drive has a capacity of 1,000 gigabytes (GB; where 1 gigabyte = 1 billion bytes). Typically, some of an HDD’s capacity is unavailable to the user because it is used by the file system and the computer operating system, and possibly inbuilt redundancy for error correction and recovery. Performance is specified by the time to move the heads to a file (Average Access Time) plus the time it takes for the file to move under its head (average latency, a function of the physical rotational speed in revolutions per minute) and the speed at which the file is transmitted (data rate).

The two most common form factors for modern HDDs are 3.5-inch in desktop computers and 2.5-inch in laptops. HDDs are connected to systems by standard interface cables such as SATA (Serial ATA), USB or SAS (Serial attached SCSI) cables.

Bristol is a city, unitary authority area and ceremonial county in South West England, with an estimated population of 433,100 for the unitary authority in 2009, and a surrounding Larger Urban Zone (LUZ) with an estimated 1,070,000 residents in 2007. It is England’s sixth and the United Kingdom’s eighth most populous city, one of the Core Cities Group and the most populous city in South West England.

Historically split between Gloucestershire and Somerset, the city received a Royal charter in 1155[citation needed] and was granted County status in 1373. From the 13th century, for half a millennium, it ranked amongst the top three English cities after London, alongside York and Norwich, on the basis of tax receipts, until the rapid rise of Liverpool, Birmingham and Manchester during the Industrial Revolution in the latter part of the 18th century. It borders the counties of Somerset and Gloucestershire, and is also located near the historic cities of Bath to the south east and Gloucester to the north. The city is built around the River Avon, and it also has a short coastline on the Severn Estuary, which flows into the Bristol Channel.

Bristol is the largest centre of culture, employment and education in the region. Its prosperity has been linked with the sea since its earliest days. The commercial Port of Bristol was originally in the city centre before being moved to the Severn Estuary at Avonmouth; Royal Portbury Dock is on the western edge of the city boundary. In more recent years the economy has depended on the creative media, electronics and aerospace industries, and the city centre docks have been regenerated as a centre of heritage and culture. There are 34 other populated places on Earth named Bristol, most in the United States, but also in Peru, Canada, Jamaica, Barbados, and Costa Rica, all presumably commemorating the original.
