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.
