A device for storing and recovering digital information, principally being Computer data can be referred, as A Hard Disk Drive (HDD), also known as, hard drive or hard disk or disk drive. It comprises of one or more hard rapidly, rotating disks called as platters. These rapidly, rotating disks are coated with magnetic material and with magnetic heads, having an ability to write data to the surface of the disks and also, read from the surface of the disks.
Hard drives have very good recording capacity; cost, reliability, and speed have kept pace with the requirements, for secondary storage. To summarize, a hard disk is one of the most important secondary storage units. A hard disk can fail, due to several reasons, like exposure to fire or water or high magnetic waves or suffering a sharp impact or environmental contamination. This can lead to a magnetic head crash. If a hard disk crashes, hard disk recovery is of at most importance, as it contains important data.
In order, to avoid, the loss of data due to disk failure, common hard drive data recovery service includes: Data backup is the process of backing up data, which means making copies of data, which can be used to restore data for a future dates, in event of data loss .Types of hard drive recovery services include On-line backup storage, Near-line storage, Off-line storage, Off-site data protection, Backup site or disaster recovery centre (DR centre).Devices like palmtop and laptops are more, prone to mechanical damage.
For such systems, most common hard disk recovery service would be the technology termed as S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology). This is a system, for computer hard disk drives to detect and report, on various indicators of reliability, in the hope of anticipating failures. A backup of the original factory condition, as configured by the Original Equipment Manufacturer (OEM) or the preferred condition of the computer by the end user is a recovery disc. While buying a computer, the Original Equipment Manufacturer (OEM) will give details on, how to use the recovery media.
This will help the end user to format, the hard drive, reinstall the Operating System (OS) and also, reload the pre-loaded software to either, the original factory condition or the preferred condition of the end user. Original Equipment Manufacturers, using Windows Operating System, like Windows 2003, Windows NT etc will supply, the necessary boot device, as it involves booting, from a separate CD-ROM or DVD; this, in turn, launches the recovery environment. But, the recent practise newer Operating Systems like Windows Vista and Windows 7 involves a hard disk partition to store recovery data.
The practice of supplying bundled CD-ROMS has become less common. The partitions on newer Operating Systems, in hard disk are termed as recovery hard drive. The hard disk drive can be accessed by pressing certain combination of key words, during boot and the system can launch and restore system. The main advantage of OEM Built recovery service is the speed and the cost. However, the disadvantage is the system cannot be restored, if the hard disk crashes, completely.
