A Hard Disk Drive (HDD) also, known as hard drive or hard disk or disk drive is a device, for storing and recovering digital information, principally being Computer data. It is made of one or more hard rapidly rotating disks also, called as platters. Hard drives are classified as non-volatile, random access, digital, magnetic, data storage devices. 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, the knowledge to recover, the data from hard drive is of at most importance. In order, to avoid the loss of data due to disk failure, common recovery services include: 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 event. Types of hard drive data recovery services include, the On-line backup storage, Near-line storage, Off-line storage, Off-site data protection hard drive recovery service, Backup site or disaster recovery centre (DR centre).

Data redundancy occurs, in database systems, which have a field that is repeated in two or more tables. For instance, in case, when customer data is duplicated and attached with each product bought, then redundancy of data is a known source of inconsistency, since customer might appear with different values, for given attributes? Hence, this repetitive data can be used, in case, of data loss in hard disk. Laptops, palmtops etc, are more prone to impact, as they are frequently carried around. Any mechanical damage or reduction of mechanical damage to the hard disk drive can be reduced by preparing, the disk prior to impact. This technology is termed as Active hard-drive protection. S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a monitoring system, for computer hard disk drives to detect and report on various indicators of reliability, in the hope of anticipating failures.

For any kind of data recovery, the easiest would be to change the circuit board by using an identical hard disk .If it is the read-write head that is faulty, it can be changed. If is lucky and the disk platters are undamaged then data can be transferred to another identical hard disk. If it is a disk platter failure, disassembly of the disk platter is required and the disk has to be reimaged. For logical damage to file systems, there are a variety of tools including fact on UNIX-like systems and chkdsk on Windows.

Every data recovery case is unique, and that the price, you might pay, depends on a number of factors: how many files, do you need restored, what is the physical condition of the disk or drive, how complex is the recovery? All of these, questions can have an impact on, how much you may pay, for data recovery. Hard drive data recovery price can be anywhere, from $100 to $ 20000.
