About RAID Data Recovery

A wide majority of small-to-medium business enterprises across the world have nowadays turned to RAID-configured systems, services for most if not all of their storage solutions. Some of the most frequently given reasons for opting to utilize RAID Arrays services in business enterprises today are the highly fault-tolerant levels that the solution offers its users and the most of all the cost effectiveness of the acquisition and maintenance of the system.

This is, however, accompanied by an anticlimax that, if for some reason a RAID Array fails as may be a result of component malfunctions (such as hard disk drives and controller cards) or even in the event of operating and application corruption, then it leaves all the data unusable and in most cases than not corrupted.

RAID data recovery is an extremely intricate task since the RAID data configurations most of the times have different forms of data layouts depending on their manufacturers, this is often for competitive purposes. Therefore, it goes without saying that without an in-depth and acute knowledge of how RAID arrays are usually configured in hardware, firmware and even software levels, the data recovery attempts will not only fail completely, but will also result in far much worse data corruption.

By putting into use its vast knowledge of RAID Array storage technology systems, some companies such as Seagate Recovery Services can reliably and successfully manage to recover data from the very earliest to the most recent SAN, NAS and Server RAID configurations available in the market today.

Guidelines for Raid Data Recovery

In the event that you have realized that you are handling a RAID failure and therefore you will need Raid Data recovery, the first step is to write down all that you know about the original configuration of the array i.e. ensure that you label all the member disks with a marker. These, along with the drive disks, also label the controller ports and all the cables. Then subsequently you can use the numbering format to refer to any particular disk. RAID recovery normally implies the recovery of logical RAID configuration that is made up of the following parameters; RAID type, number of its member disks and their order, block sizes, start, offset for data on member disks (this information is in most cases not given).

The logical RAID configuration is accessible in RAID controller BIOS or in RAID monitoring and configuration software. If you manage to determine all parameters, RAID recovery is accomplished for you. All the information relates to the preparation to RAID recovery that aims at reconstructing missing RAID configuration parameters. All of the information given above must be collected so as to enable you return to the original configuration should there be a need to.
