Always seek Professional RAID recovery service to avoid permanent data loss

RAID stands for Redundant Array of Independent Disks

. RAID is an advanced data storage technique that is used to make a single fault tolerant system by taking multiple number of low cost hard drives linked together via a controller chip. In RAID, data is distributed across multiple hard disk drives and in a way increases the storage capacity, performance and data safety. Apart from all the good things, because of their complex data storage pattern, data loss situations in RAID systems are more difficult to deal with. However, various RAID restore techniques and RAID data recovery services can help recover your data from critical RAID failure situations.

Some of the major reasons behind RAID failure:

There can be numerous reasons behind a RAID failure, however, below are some of the common cases of RAID failure, directly linked to the RAID configuration:

RAID controller Failure.

RAID array Failure.

Rebuild Failure.

Damaged strip.

Possible damage to the RAID configuration.

Different categories of RAID levels:

There are different categories of RAID levels available, with respect to their storage pattern and fault tolerant mechanism. RAID 0, RAID 1, RAID 5 is considered to be the simple RAID levels, whereas, RAID 10, RAID 50, RAID 6 and RAID 6EE are considered as the complex ones.

If a single disk fails in a RAID level 5 based systems or above, you are still able to rebuild the disk by simply replacing the damaged disk with a good one. The problem gets higher, when there is a failure of multiple numbers of disks simultaneously. In such a case, data loss is indeed problematic to handle. Moreover, any wrong step in haste can lead to a definite loss of data beyond recovery. So, it is better to consult and seek professional RAID data recovery services, whenever there is a RAID failure.

Professional RAID recovery process:

All the accessible hard disks in the RAID system are cloned in order to avoid damaging the original media and the data in it.

The inaccessible drives are repaired inside CLASS 100 Clean Room labs to make them ready for cloning.

Data from different volumes in the RAID system are saved to a single contiguous memory.

Then the length of the RAID strip is determined using special technique and close observation.

The RAID controller is analyzed to understand the data distribution algorithm and thereby the parity strip movement.

In case, the controller card is damaged, with extensive research, the controller algorithm is reformulated.
