RAID Data Recovery

In case of failure occurs RAID, RAID data recovery can be very difficult. However, it is an impossible task. Data recovery depends on many factors.

For example, the height of the matrix plays an important role in its ease of use. RAID level 0 is a striped array without fault tolerance. If a hard disk array fails, all data is accessible. RAID 1 is a symmetrical fault tolerance. IfMirroring hard drives, data can be easily retrieved from the mirror the other disk to level 5, data is striped with parity. If a drive fails, the degradation of the matrix, but the data are usually on the Internet. If the failure of two disks, the data is lost. Therefore, it is easy to see why the RAID levels used impacts RAID recovery.

Another factor to consider is the disk array. Oftenthere is nothing wrong with the disks in the RAID configuration and the problem itself, but mostly there are errors on the disk, making the image online. Disks in the array can be many problems with bad sectors cyclic redundancy error and mechanical failures. The signs of hard drive failure can do with the presence of flashing lights on the server. Sometimes you may hear the evidence of mechanical failures such as clicking on the disk. The data valuedepends on the hard drive and problematic, it can be repaired.

Another factor that comes into play is if the plant was built with the software or hardware. A series of software is integrated into the operating system and does not use the hard disk controller. A series of equipment for the physical inspection. Problems can arise with the hardware and software that is causing the table is not displayed.

If a series is successful, it is important to help identify expertsto restore the data. errors, the data can be edited or deleted. It 'also important that the disks in the correct order and document the events that took place before the blackout and how to label RAID failure.

RAID data recovery can be difficult, but not always possible. For a positive result, the recovery RAID recovery companies always done by a professional data.
