Professional RAID recovery in case of Controller failure

RAID consists of a multiple number of low cost hard drives, which taken together as one single logical drive. RAID follows a pattern in distributing data across various drives and are managed by the controller chip. The RAID controller, which is a hardware device is actually incorporates specially programmed controller algorithm to store and manage data across the drives attached to the RAID array. That is the reason, the smooth functionality of the RAID system depends upon the well being of the controller chip. However, in case, the controller of your RAID fails, you need to opt for any professional RAID recovery service to rebuild your RAID.

About the RAID controller:

In general, the RAID controller has two distinguished parts, one is the front-end and the other is the back-end. Where the front-end links to the host adapter, the back-end part establishes the communication with the attached individual disk drives. The RAID controller uses parallel data paths for faster data transfer in RAID arrays(Up to 35 MB per second) and the feature is indeed a noted feature of the same. As the controller manages the functioning of the entire RAID system, any problem to it results serious data loss in RAID.

Significant error messages that signal RAID controller failure:

Among many possible instances of RAID controller failure, below are some of the most common cases, which signal a definite problem with the controller:
Stopping of the write process
Error- “Read ahead buffers timeout”
Error- “Array controller failure
[command failure (cmd= , err=)]” etc.

Under all the above situations, data from one or more drives in the RAID array becomes completely inaccessible and even you can not be able to rebuild the same. Furthermore, any wrong step can add more criticality to the situation and you may end-up loosing data permanently. Therefore, for the sake of your precious data in the drives, it is wise to opt for any professional RAID recovery service provider.

Moreover, RAID data recovery is a systematic scientific operation and obviously a job of an expert. Hence, never ever rely on any inexperienced service provider and avoid experimenting, as about RAID, it is a widely accepted truth that the first recovery attempt has the best chance of maximum possible recovery.

Professional RAID recovery services for individual entrepreneurs to industries

With the growth and development of bigger enterprises, to meet the need of storing huge volume of business data and to make the whole system/server a fault tolerant one, technologies like RAID was invented. RAID is a highly advanced storage mechanisms of the recent time, through which organizations build a single system by accumulating multiple number of individual disk drives, which can be controlled by a controller chip. RAID is excellent in terms of storage efficiency and to many extent resistant to data loss. However, due to their complex storage pattern, if any instance of data loss or inaccessibility happens in RAID, it is extremely difficult to safeguard the data in it. Under such complex situations of RAID failure, the best decision is to immediately seek professional RAID recovery services for the safe recovery of your valuable data.

A brief about various RAID levels:

There is a long list of RAID levels in terms of their data storage pattern and ease of resisting the data loss situations. Among them, RAID 0, RAID 1, RAID 5 are normally considered as the simple RAID levels and RAID 10, RAID 6, RAID 6EE, RAID 50 etc are taken as the complex categories of RAID. According to your need, you can choose any one or multiple RAID levels to configure the RAID system.

As the RAID system has been built with multiple individual disks, any problem related to the functionality of these drives can cause data loss in RAID. However, in RAID level 5 or above, if a single disk fails, the system can easily cope with the situation and by replacing the troubled disk with a new one you can be able to rebuild the whole data again on the new disk. But, the problem gets serious, if multiple disks fail simultaneously. Under such a condition, a small mistake in handling the system may cost you the whole data in the RAID system. Hence, it is always the safest way that you avail the services of any experienced RAID data recovery solution provider.

Apart from the normal hard drive failures, there can be many RAID specific problems which can lead to data loss or inaccessibility in a RAID system, such as:

Damage of the RAID controller.
Failed RAID array.
Failing to Rebuild due to the insertion of incompatible/troubled disk.
Damage of the RAID strip.
Damage to the RAID configuration.

Basic Dos & Don'ts for the safety of your valuable data in RAID:
Avoid running any repair utility on the inaccessible RAID drives.
Strictly avoid the defragmentation of drives without ensuring their good working status.
Immediately stop rebuilding, once you find the failing of multiple dives.
Ensure the drives are marked as per their positions in the RAID array.
Use the new disk drive, which is zero filled and has greater or equal number of sectors than that of the troubled drive.
Immediately see professional RAID recovery services to avoid loosing your data permanently.

Need of RAID Recovery

The term RAID stands for Redundant Array of Independent Disks. RAID is a collection of series of hard disks in the form of array. The aim of this system is to reduce the chances of data loss by storing same data at different places on various hard disks.

RAID system increases the reliability of data by storing it in series of hard drives. As if one of the hard drives from the series goes corrupted the data will remain protected on another hard drive in the series.
Because of this speed and availability of the data also increases. And it is quite not possible that all the hard drives in the array get corrupted simultaneously. RAID is divided into various levels as RAID 0, RAID 1, RAID 2, RAID 3, RAID 4 etc. in which data is repeated between various hard disks.

But sometime mishappening take place because of which your system goes corrupted. And it may be due to various reasons:

1. Virus attack
2. Power Failure
3. Controller failure: RAID system has various hard drives but only one controller; if it gets corrupted then automatically whole system will not work.
4. Wrong configuration of drives.
5. Natural calamities like water, fire etc.
6. Bad sectors in RAID array.
