Now we live in this century, when the most valuable thing we have - is information. Its loss can lead to various troubles, such as financial losses. This is because in our day life full of computers and other devices containing, large amounts of information. But, unfortunately, nobody is safe from computer failure, and other devices. RAID (Redundant Array of Inexpensive Disks - redundant array of inexpensive disks) - a way to combine multiple hard drives into one virtual device in order to increase the speed and reliability. In most cases, RAID is used for multi-enterprise servers to store large amounts of information. When failure of the array, blocked the work of the entire organization, so in the recovery disc information most important thing is the time for which the data will be restored to the RAID. We understand the criticality of the situation and for this we offer this service as a RAID rebuild the clock. Here, we will not give any recommendations on the restoration of RAID arrays. From my own experience, we know that any attempt to recreate the RAID non-specialists in this field, not the owner of the subtleties of the organization of an array end fatal destruction of data RAID. We note only that according to our statistics, the reasons for failure of the RAID arrays are divided into three groups: 1. Excess level of reliability of the array. In most cases, the redundancy in the arrays used in one drive, at a failure of one disk array continues to operate, but requires replacement of defective components. As practice shows, often replacing a damaged disk does not occur after a second drive failure, RAID array fails. 2. Incorrect reconfiguration of the array when replacing a damaged disk. In this case, the various options, but the essence is the same, a defective drive is replaced with serviceable, and then make the restructuring of the array, which in most cases involves mashing the primary sectors of the array and leads to loss of information. 3. Failure of the controller array. In RAID controllers there is no single standard, even the controllers of the same company may differ significantly from each other. When failure of the RAID controller, it is often impossible to find a similar controller to re-assemble it on the array. Meanwhile, all disks can be serviceable, but the data recovery process is similar to recovery from a failed array. We, of course, fully aware that complete or partial loss of information from the RAID array - it's always great strains on any company. In many areas require handling large volumes of data, and if I lose access to the company could suffer serious financial loss, or just be on the brink of ruin. In such cases, to companies to recover lost data files "matter of life and death.
