What is A RAID Server?
RAID is also known as‘Redundant Array of Inexpensive Disks or Redundant Array of Independent Disks’. This is basically a virtual data storage technology, which combines multiple hard drives into a single logical unit & works together to provide data redundancy with increased overall system performance. This technology has fault tolerance ability that encourages a system to perform all the functions, even when one or more hard drives have failed. RAID provides a highly secured environment and protects data against the data loss and losses and reduces the chances of a disaster.
RAID systems use multiple ways to distribute data in the hard drives, which are called RAID levels, for example RAID 0, RAID 1, RAID 2, RAID 3, RAID 4, RAID 5 and so on. This technology is used by a majority of small to medium sized businesses across the world as their storage solutions due to its highly fault-tolerant level and the cost effectiveness of acquisition and maintenance.
Like every technology, RAID system can also fail due to multiple reasons, which might leave the data unusable. Although, RAID recovery options also are available, however, due to RAID systems’ complicated layout, it is mandatory that the data recovery source should understand configuration level of RAID hardware, firmware and software. Any type of wrong data recovery attempt may not only fail the system but also result in further data corruption.
In any kind of RAID server failure NEVER experiment on your own to get back your critical data. It may further damage your stored data. Let RAID Recovery experts from STELLAR DATA RECOVERY SERVICES do the job for you, as one small mistake in haste, at your end, can lead to permanent data loss or beyond recovery.
Since a RAID server data is mirrored or stripped across various disks, hence, RAID Data Recovery is a very tedious task. In RAID 5 or above, if you lose multiple disks simultaneously or the RAID rebuilding terminates in the middle, the RAID failure must be handled with utmost care to safeguard the data.
RAID Data Recovery is complicated task since RAID configurations are dependent upon the data layouts. So, without proper analysis of how RAID arrays are configured at software, hardware of firmware levels, any recovery can make data corrupt and furthermore reduce the possibility of successful RAID Recovery.
Stellar Data Recovery Services, with its experts RAID data recovery professionals can successfully recover data from any possible RAID Configurations in market today.

RAID Failure – Guidelines to Keep Your Data Safe
- Label the drives in the RAID array with respect to their positions.
- Never try any repair utility on an inaccessible volume.
- Always ensure good health of the drives before Raid rebuilding.
- In case if any one of the drives in Raid 5 or above is faulty, while replacing the faulty drive, make sure that the new drive is zero filled and has sectors greater than or equal to (=>) that of the faulty drive.
- Stop the Raid rebuilding operation immediately, if multiple drives fail simultaneously.

- Never run any defragmented utility without checking the health of the individual drives.
Here is a list of most common scenarios of RAID server failure which causes data loss:
- Virus Attack
- Hardware failure
- RAID controller failure
- Damaged RAID Strip
- Data Deletion or reformat
- RAID array failure
- Software corruption
- Power Surge
- Missing RAID partition
- Loss of RAID system registry or configuration settings
- Error in RAID rebuilding or problem in volume reconstruction
- Wrongly replaced hard disk element to a working raid volume
- Accidental reconfiguration of RAID volume
- Multiple disk failure resulting in data loss
- After system or application upgrade loss of RAID disk access
RAID 1 is basically a disk mirroring, or set of two drives that are configured for data to be written in 2 volumes simultaneously. This configuration provides complete data redundancy in the event of a drive failure. Whenever a member of RAID 1 fails or become disconnected, the raid array starts running in degraded mode and data mirroring gets lost. In order to re-establish data mirroring and to restore data redundancy, the system starts waiting for a replacement of drive, which may take a day or two. During this waiting time, the drive failure of raid volume is very high due to over stress. Therefore, if one disk fails, the chances of another drive failure are probable. Many users assume that they are completely protected against data loss with a RAID 1 volume but it is actually, not the truth. A RAID 1 volume definitely provides protection against data loss but it does not eliminate the need for regular backup and recovery options.
If you are experiencing RAID Array failure, ensure that proper steps are followed to protect your data.
- Turn off the Array instantly because if the array is in use it can cause more damage to the data and retrieval might be difficult.
- Do not attempt to repair the system on your own. RAID requires clean room milieu as the atmospheric air can cause irretrievable damage.
- Contact RAID Data Recovery Professionals to retrieve the data. RAID Data recovery experts will estimate severity of damage and the data that can be recovered.
