RAID (Redundant Array of Inexpensive/Independent Disks) failure can bring a bunch of miseries for an organization. When a RAID array crashes, the reason is often considered as multiple disk failure. But, in many cases, a RAID crash can be caused by a defective RAID controller or complete failure of the vital RAID controller. A RAID controller manages hardware interfaces between the system and the hard disks, thus enhancing the reliability of a RAID array.

When a RAID controller failure occurs, all the hard disks (part of the array) become totally inaccessible. As a result, an organization has to suffer from critical data loss situations. To reduce the impact of a severe crash, an organization can rely on clean and updated backups of the data. However, if no backups exist, an organization should get in touch with the RAID experts by acquiring professional data recovery services.

Good data recovery companies might be hard to find, but do not lose heart. With the growing demand for data recovery, many ventures have established their shops in great numbers. And, you never know, you might locate one in your neighborhood area. All you have to take care is do your research and find a reputed data recovery company which has a rich and extensive experience in handling various RAID failure cases.

What are the symptoms of RAID failure?

A failed RAID array can exhibit strange behavior and throw various error messages. In fact, it is through symptoms only you can judge an impending failure and call for data recovery services timely. It is important for you to know how a RAID array behaves if its controller fails. If a RAID system is writing the information and failure occurs, you would witness the following signs:

• The write process will stop abruptly
• After rendering a clip, it will become invalid; red frames will appear
• All clips in the library and on the desktop will become invalid

If a RAID array is reading the information, and its controller succumbs to a failure, you will notice the following:

• ‘Read ahead buffers timeout’ error message
• Your desktop will be flooded with red frames

To avoid such problems, most of the RAID arrays use a second controller. In an event of failure, all the hard disks can be positioned on another controller. Since this serve as a temporary solution, you must look for specialized

RAID recovery services.
