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.

Stellar Data Recovery is a well known RAID recovery service provider in India. With all the necessary assets, for more than 17 long years, Stellar has been rendering its industry best data recovery services to large corporates as well as individuals.

Physically Damaged Drives? Opt for Data Recovery Services for Safe Recovery

In spite of taking many measures to prevent instances of data loss, we still come under the grip of it almost every day. Loss of valuable data can be due to an accidental deletion, virus attack, formatting of the media, operating system malfunction, hard drive crash etc. With sheer work pressure and changing technologies, it is practically impossible to avoid the occurrence of accidental data loss. Moreover, sometimes the situations are so worse that you do not even able to boot-up the system or the hard drive is making some unusual grinding noise at the start-up, forcing you to turn it off. For those instances of data loss/inaccessibility, it is better suggested to opt for any data recovery services, rather experimenting, when your precious data is on stake.

Among many possible instances of data loss, the situations which arise because of any physical damage to the storage media are the most critical ones. Following are some of the common cases of data loss:

Appearance of an unusual blue screen at the time of booting.
The system fails to boot further, hanging infinitely at the start-up screen.
Unusual grinding or clicking noise is coming out of the hard disk.
Hard disk remains silent even power being on.
Missing of files and/or folders.
The system repeatedly restarts, failing to boot further.
The hard drive is completely undetected by the BIOS.
Spilling over of any liquid.
Visible damage to the media by hit or drop.

Situations as above do happen accidentally and many users get tempted to open the hard drives and repair them. The result of such an act is nothing but disastrous and they end-up loosing all their data from the drives. Data recovery is very much possible until the lost or inaccessible data is not being overwritten with some other data. Apart from this, if you open up the storage media in normal environment, the dust particles may go within the platter and the head, resulting in severe damage to the patter & permanent data loss.

Hence, any physically damaged media must be opened and repaired only inside CLASS 100 Clean Room labs, where there are even less than 100 dust particles, below the size of 0.5 microns per cubic foot of air. Moreover, hard drive recovery is a systematic scientific process and must be performed through experienced professionals.

The company is in the field of data recovery for more than 17 years and with advanced utilities, skilled recovery engineers, vast inventory of hard disk parts, CLASS 100 Clean Room labs is the most trusted data recovery services provider in India.

Always Opt for Professional Hard Disk Data Recovery for Safe and Timely Recovery

Whether for office use or it is for home, hard disk of a computer stores the major portion of our data. Usage of various applications, human errors and regular exposer to different types of data over Internet make hard disk of the computer very much vulnerable to data loss or inaccessibility. As, many users store large amount of recent data, any data loss situation raises serious hue and cry. However, with advanced techniques like hard disk data recovery, all your lost, deleted, formatted or inaccessible data can be easily recovered back.

Many instances of data loss are so accidental that they never can be avoided. Moreover, though it is advised to take regular backups of the important data, at times it is practically impossible. Below mentioned are some of the most common cases in which you may lose hard disk data:

- The computer system failed to start-up.
- Received the unusual Blue Screen of Death while booting.
- The hard disk of the system can not be recognized by by the operating system.
- There is no sound of hard disk movement even if it is powered on.
- An unusual clicking or grinding sound is coming out of the hard disk of the computer.
- Visible damage to the chips and/or the connectors of the hard disk.

Under all the above instances of data loss, the good thing is that data is never permanently lost until that is being overwritten. Hence, once you encounter any problem with your hard drive, care should be taken not to over write the existing data with new one. You must always avoid disk-defragmenting, installation of new software, saving data to the troubled disk, tapping or heating the disk etc. Moreover, in no condition, open the hard disk, as the dust in the environment can come within the head and platter of the disk causing scratches on the magnetic surface and permanent data loss.

Hard disk data recovery is a specialized scientific operation and should only be performed by the specially trained experienced professionals for the safe and in-time recovery. Above all, physically damaged hard drives should only be opened inside CLASS 100 Clean Rooms.

Note: A CLASS 100 Clean Room is a technologically controlled closed room, where the number of anomalies present is less than 100, with the size less than 0.5 microns per cubic foot of air.

For more than 17 years, Stellar Data Recovery has been the most reliable hard disk recovery service provider in India.
