Raid recovery is possible only in a single case - when there is a physical failure of hard drives. In case of any other failure, partition recovery is virtually impossible. RAID array is a system of conventional reservoirs, which consist of discs. To manage the entire array, the controller is used and for the server the entire array appears as a disk that contains high capacity.
Restoration of RAID arrays can not guarantee complete security of all your information if failure occurred during the controller operation. Also, in case of a failure of equipment or improper operation of the array all the information is at great risk of loss. Virus attacks, which often adversely affect the data saved on disks, can also lead to the escape from the operating mode.
Restoration of RAID arrays is required to recover the vast amount of information that is stored in ROM. There are several types of RAID arrays.
The first is RAID 1. Their work is like a mirror image on two drives. In case of failure of one of them, all information is easily restored with a different disk. An improved and a new kind of arrays is RAID 5. Their zest is that they continue to operate even when there is a failure of one of the disks. However, it concerns only the breakage that happened due to physical failure. If the cause is the failure of a disk controller and hit of different viruses in the program, then no kind of disk arrays will be able to keep important information for you.
Restoration of RAID arrays after failure of the controller causes a change in the construction of all files and folders, which are mixed with each other in a chaotic manner. Using the normal way without any special recovery software, you will not extract any information.
Restoration of RAID arrays becomes very complex and difficult to achieve if using the tools, users incorrectly install new disks and programs, or use them for other purposes. Often such slips lead to partial or complete loss of information.
