Data Loss from RAID is still Possible
RAID or Redundant Array of Independent Disks is a technology which has been developed to improve the efficiency and to achieve greater levels of performance. It employs the simultaneous use of two or more hard disk drives on which the data is divided or replicated and thus increases the data reliability and input/output performance. Better read/write speeds over a single drive servers and better fault tolerance add to the list of RAID achievements.
But as all the technologies are not fool proof and so the RAID technology is. The data loss still happens similar to single hard drive systems. But this problem is even worse as the data stored on RAID is more business critical as most of the companies are moving to it due to its extra ordinary brilliance.
The system may break down if whole of the hard disks used fail at the same time or if the RAID controller fails to recognize the disks in the array. The reasons can be any but the ultimate loss is the data which keeps a great importance. So to keep the data safe there are few of the preventions which could be taken in order to prevent the data loss:
1. While copying the data from the old hard drive onto the disks to be used in the array, keep the copy to you for some time to avoid future faults.
2. More number of disks should be used in multi user environment needs
3. Make a regular check of the data stored on the disk as despite of its great performance files can still disorganize or damage.
When a RAID system starts malfunctioning or broken down, some of the business associates think that their data is no further recoverable as told by few of their consultants and IT staff. But to correct them at this point this fact is not true at all. The common practice followed by the RAID users is to follow documented administrative procedures such as forcing the RAID controller onto the same configuration. But this could lead to more problems of data loss.
The data can be recovered from RAID whatever the case may be. The solution entirely depends upon the cause of the failure. If the hard disks have failed or have undergone some physical damage then the recovery in the data recovery service is recommended while in other of the cases the recovery through suitable data recovery software is done.
Stellar is one of the leading company which provides you both the ways of recovering the data. Stellar class 100 clean room facility ensures a customer a sure and absolute data recovery from all the physically damaged hard drives. The environment provided here is suitable for a complete data recovery. Data recovery experts always keep this point in their mind the atmosphere should be dust free while performing their part.
The data recovery software provided by the company hold the best surety to recover data. No matter which operating system you are using, these software are available for each one of them including Windows, Linux, UNIX, Novell and Macintosh. You need not to be technical expert to use the software as they give an easy to operate interface. In any case of RAID data loss the software are here to help out.
