In computer, data recovery is basically a procedure of recovering lost, corrupted, damaged, erased or unreadable data from external media, secondary storage or removable drives. This is done by restoring it from the state it was in before the error occurred. Data can be recovered from both physical and logical storage media and removable storage devices, such as USB, FireWire, SCSI, CD-ROM and floppy disks. Data recovery software is used to do this.
If your hard drive crashes or gets infected with a virus, then you will be unable to access or delete the files stored on it. Data loss can also occur due to hardware failure or system crash. In case of hardware failure, it may result in permanent loss of data.
The recovery process requires different methods depending on the type of data lost. Physical media can be retrieved from either floppy diskettes or the hard drive. There are many computers data recovery programs available for this purpose. Physical media can be retrieved using a data recovery software such as Nero or defragger, but this can be a time consuming and difficult task to perform. Hence, some of the best techniques for data recovery are discussed below.
Data recovery using software and techniques like registry scan and repair and system restore is easy and quick compared to manual recovery. Such programs are easy to use and can be performed by any computer user. They can recover all the data of the hard drive including deleted files, temporary files, internet cache, temporary Internet files and Internet cookies. Moreover, such programs can recover all the data of the external hard drive.
Recovery of deleted files or Internet cookies from your internal drive is not that easy. You need an extensive backup of all important information in order to get such files back. Even if you do so, it is still not guaranteed. Hence, manual data recovery will be more effective and efficient.
Data loss can also be caused by corrupt programs, viruses, spyware, worms, Trojans and malware. They can cause data loss by changing the files, folders and settings of the system, making the operating system unstable. Thus, a data recovery program is needed to retrieve such information and restore the data.
Recovering data from your hard disk can be done in several ways. You can get it manually, get it recovered by using a data recovery software or even get it recovered by recovering your PC registry. You can even recover data from USB drives. All these options are equally effective and are equally time consuming.
