Data recovery is the act of recovering data that has been lost due to physical damage such as a virus or a mechanical failure. It can also be recovered from a storage device that has suffered some type of data loss. There are different types of data recovery techniques and methods. For instance, it can be recovered from a memory card, a floppy disk or an external hard drive. The techniques that work best for each specific case depends on the nature of the data that was lost and the reason for its loss.
A data recovery service specializing in small business is a company that specializes in the restoration of lost data from various sources such as hard drives, flash drives, memory cards, etc. It usually performs all sorts of recoveries from file systems and other storage devices used in small businesses. A small business data recovery service might use various techniques in an effort to recover your lost data.
One of the most popular techniques used by data recovery services is called file and hard drive overwriting. This method consists of writing over your data into a completely new location and then overwriting the old data location with new data. Although this technique provides good coverage of the possible data locations, it is not very reliable and effective. File and hard drive overwriting has proven to be effective and reliable in recovering data from many types of storage devices like memory cards, hard drives, Zip drives and Compact Disks.
Another good technique is the automated defragmentation. When a file or a folder becomes fragmented, its size increases. This fragmentation will eventually make the hard drive physically smaller. When this happens, it takes more time for the entire data set to be stored in a single location. The automated defragmentation can help stop using a smaller external hard drive or a compact disk and can speed up the retrieval of data.
There is also another data recovery technique that uses an external hard drive or a CD-ROM that can be connected to an internal SSD storage device. If this CD-ROM has been formatted, the data recovery software can read the information from the disk. One drawback of this technique is that you might need an external SSD storage if the internal drive has failed.
Data recovery firms can also use different data recovery techniques that do not require physical access to the storage device. Magnetic disk writing is one such technique that can recover data from all sorts of hard drives including cd-roms and memory sticks. This method requires no manipulation of the media and no removal of any material from the storage media. The magnetic disks are written over and only a blank space is left for data storage.
A data recovery firm can also employ thermite to destroy data on a hard drive. It is a method used mainly by big companies to retrieve important data that is impossible to retrieve even with advanced tools. Thermite causes a layer of melting at the surface of the hard drive which causes irrevocable damage to the data on the device. The data recovery service provider will remove this layer and if the device is still under warranty, the device can be sent for repair or replacement.
The data recovery firm should also stop using the drive once the damage caused has been done. This is because it does not make sense to just keep the drive spinning around if there is no use of it. The data recovery firm should dispose of the drive once the damage caused has been done. By doing this, they ensure that the drive cannot be used for data recovery purposes in the future.
