The data recovery from the hard disk is the process of restoring the files from the hard disk such as pen drive, flash drives or the USB Drives. The common cases of the data loss are the cause of either human error or the technical failure or sometimes, the failure of a hard disk. You, as a computer user must be aware of the fact that the data do not get lost completely immediately after you click the deletion option. It either goes to the recycle bin in Windows, in Trash if you have installed the MAC operating system in your PC or it remain in the hard disk. The necessary condition for the successful accomplishment of the lost or deleted files is that the deleted files must not be overwritten. If the file gets overwritten, then there is no software which can assist you to restore the lost files.
The accomplishment of the data recovery is very much possible even if you have formatted the hard disk, re partitioned it or even re formatted it.
When you format the hard disk all the data gets lost but it still remains in the hard disk. The data recovery software will offer you the necessary steps to get that data back to the system. When you press the keys Shift + Delete for the purpose of deletion, then the data do not go to the recycle bin, in fact it goes to the hard disk and stores there. In this condition it is not possible for you to restore the files from the hard drive, if you do not have the data recovery software installed in the system. So, install the data recovery software in the OC now only and avoid the possibility of the files being overwritten. In case of the logical failure, the user gets the interface by the recovery software which can guide him/ her to the location where the data were stored.
The Microsoft Windows operating system has the drawback that it does not offer the inbuilt recovery software which can straight away guide the user on the location of the deleted files.
Although, the recovery software is so popular in the market, but still there are many computer users who are unaware about the presence and the benefits of this software. The technology known as the Redundant Array of the Independent Disks also plays a vital role in avoiding the possibility of the lost data. The RAID (Redundant Array of the Independent Disks) enables the data to be replicated and it allows it to be stored in the hard drive. The hard drives are the threats to the working of a computer because they have the ability to store a large small volume of data, which sometimes speed up the process of operation and hence consequently ends up in the technical failure.
The RAID is available in a large number of version and help significantly in the process of restoring the lost files.
