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.

Leeds is a city in West Yorkshire, England, the principal settlement in the City of Leeds metropolitan district. In 2001 Leeds’ main urban subdivision had a population of 443,247, while in 2011 the City of Leeds had an estimated population of 757,700 making it the third largest city in the United Kingdom.

Leeds is the cultural, financial and commercial heart of the West Yorkshire Urban Area, which at the 2001 census had a population of 1.5 million, and the Leeds-Bradford Metropolitan Area, of which Leeds is the integral part, had a population of around 2.3 million, making it the fourth-largest metropolitan area in the UK. In addition, the Leeds City Region, an economic area with Leeds at its core, had a population of 3 million. Leeds is the UK’s largest centre for business, legal, and financial services outside London, and its office market is considered the best in Europe for value. Leeds is considered a Gamma World City, alongside cities such as Phoenix, St. Petersburg and Valencia under the 2010 GaWC study.

Historically in the West Riding of Yorkshire, the history of Leeds can be traced to the 5th century when the Kingdom of Elmet was covered by the forest of “Loidis”, the origin of the name Leeds. The name has been applied to many administrative entities over the centuries. It changed from being the appellation of a small manorial borough, in the 13th century, through several incarnations, to being the name attached to the present metropolitan borough. In the 17th and 18th centuries Leeds became a major centre for the production and trading of wool. Then, during the Industrial Revolution, Leeds developed into a major industrial centre; wool was the dominant industry but flax, engineering, iron foundries, printing, and other industries were important. From being a compact market town in the valley of the River Aire in the 16th century Leeds expanded and absorbed the surrounding villages to become a populous urban centre by the mid-20th century.

Public transport, rail and road communications networks in the region are focused on Leeds and there are a number of twinning arrangements with towns and cities in other countries. Its assigned role in the Leeds City Region partnership recognises the city’s importance to regional economic development, and will now play a large part in the UK’s planned new high-speed railway development.
