What You Should Know About RAID Data Recovery

Under normal conditions, when a hard drive fails, the stored data and information can not be accessed any more. However, Most hard drive failures, specifically the mechanical failure, do not actually erase or remove the data on platter surfaces. It means, this is possible to recover lost data in most of such cases using special procedures. The process of retrieving missing, inaccessible, and deleted data from computer storage devices is known as Data Recovery. The recovery method may vary, as per the cause and type of data loss.
You can minimize the possibilities of data loss situations using advance technologies, and RAID (Redundant Array of Inexpensive/Independent Disks) is one among them. RAID provides high level data storage reliability and performance with low-cost components. RAID can replicate or divide your data among several hard drives, according to the RAID levels (like RAID0, RAID1, RAID3) etc.
However, RAID levels that uses striping, can complicate the recovery process. The data is not placed in comparatively simple way on single hard disk rather, disseminated across several hard disks. Despite this situation, it is feasible to retrieve data in most of the hard drive failure cases; it costs more because of the complexity of RAID array.

As compared to a single hard drive, the RAID array has redundancy and provides fault tolerance, which means a drive failure does not cause data loss in most of the cases. When any fault takes place, and it is handled competently and quickly, in majority of the cases the requirement of Data Recovery does not arise. If more than one drives in RAID array fails, you can not easily rebuild it and need recovery solutions.

In case of logical data loss situations, such as file system corruption, virus infection, operating system malfunction, and hard drive formatting, you can get your valuable data recovered through Data Recovery Software. The applications use high-end scanning techniques to methodically scan the affected storage media and extract all lost, missing, and inaccessible data from it.

On the other hand, physical data loss cases like read/write head crash, spindle motor damage, disk controller failure, and power surges, need Data Recovery Service to be handled. It is a personalized and sophisticated help offered by recovery experts to repair or replace damage components of the drive and extract data from it.
Stellar Information Systems Limited is the leading provider of high-quality recovery solutions to handle all data loss situations. The recovery service is delivered through Class 100 Clean Rooms for SCSI, SATA, EIDE, and IDE hard drives. There are also various software available online for recovering data from hard drives based on Windows, Mac OS X, UNIX, Linux and Novell operating systems.
