Invention of RAID has given industries a new boost with high data storage capacity. RAID is a technology of the recent time, through which you can build a fault tolerant system taking together multiple number of hard disk drives. In case of a RAID system, data is distributed across different hard drives in a particular pattern and the whole process of storing and accessing data in a RAID system is managed by the controller chip. In spite of the fault tolerant mechanisms, the RAID system undergo serious cases of data loss. Moreover, due to their peculiar data distribution pattern and complex storage architecture, the RAID recovery process is indeed very much complicated.
In RAID, there are various levels, with respect to the data distribution pattern and the fault tolerant mechanism. RAID 0, RAID 1, RAID 5 are considered as the simple RAID levels, where as RAID 50, RAID 6, RAID 6EE etc. are considered as the complex ones. In systems with RAID level 5 or above, if there is a single hard disk failure, you can restore the data by the 'REBUILD' operation. Rebuilding can be easily done by replacing the damaged drive with a new healthy one. The problem gets really critical, if there is a simultaneous failure of multiple hard drives.
During such a critical condition of RAID failure, if you make a single mistake, you may loose all your data from the drives. Hence, it is always advised to take the help of any professional RAID recovery service provider for the safe recovery of your precious data.
There are many possible cases, in which the RAID system may fail resulting in the loss/inaccessibility of data. Following are the list of such reasons:
- RAID controller failure
- Damaged strip
- The RAID configuration has been badly damaged
- Rebuild failure
- Malfunctioning of the operating system
- Simultaneous failure of multiple hard disks in the RAID array
- Any other hardware/software contradiction etc.
Under all the above instances of RAID failure, you must be careful in dealing with the troubled drives. Moreover, once after encountering any instance of RAID failure, remember to note down every RAID data recovery process, you follow to trouble shoot.
