Data Recovery specialists work toward retrieving “lost data” on computer hard drives. The keyword in the latter statement is “lost”; no data is really lost on a hard drive, in fact, at least 85 percent of the time it is merely irretrievable. In addition, data recovery can not only be conducted on computer hard drives, but data recovery attempts are often successful on magnetic tapes and magnetic discs. As a final point, the most popular type of data recovery can be identified in the various software applications that help computer users restore their computers in the event of an ever-fatal computer crash.Data recovery specialists are armed with advanced knowledge and their services far surpass that of software applications. The difficulty with many software applications is that the user is often an amateur at data recovery and is therefore attempting to fix a problem that he or she cannot necessarily outright identify. The user finds out rather quickly that data recovery is more than just rebooting the hard drive or reinstalling a program. In essence, by using software data recovery programs an inexperienced computer user may merely be grasping at straws as he or she struggles to repair the computer damage he or she is faced with. What is worse is that, more often than not, the computer user is adding such applications to a computer that is already damaged. Consequently, the software applications that are meant to repair the computer may not install correctly or they may not repair the problem at all – in fact, some could make data recovery even more difficult.
If your computer files are of extreme importance to you, it is time to call in the specialists. Data Recovery experts are far more successful at retrieving that which is seemingly irretrievable like lost or accidentally deleted files. In fact, less than fifteen percent of all of the computers handled by data recovery specialists are deemed as non-restorable.
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.
