What Causes RAID Failure and How to Recover From It
RAID failure can bring a business to a virtual halt so bringing the information back and secured on the computer is important. RAID failure recovery is possible from the computer itself and there is also software available to help get that information back so you can get it copied and running on a working volume.
Many people were misled to think that information on RAID could not be lost. It can come as quite a shock to find out that it can be. Information CAN be lost from one or more discs and either professional or professional software may be necessary to regain that lost information.
When one hard disk fails, very often, there is no ready standby. Consequently, the raid array is running on degraded mode. While waiting for the replacement drive which may take a day or two, there is an increased likelihood that another disc will fail. Some reasons for RAID failure include:
- Virus attack
- Data deletion
- Missing RAID partition
- Loss of RAID configuration settings or system registry
- Loss of RAID disk access after system or application upgrade
- Power surge
- Malfunctioned Controller
Be warned though. There are many "quick fixes" typically used by clients attempting to restore a failed RAID that actually cause more harm than good. If you have a RAID failure, it is best if you do not try to recover the RAID yourself using "quick fix" techniques or "off-the-shelf" data recovery software. Never leave computer issues to unknown people or products. There are some reliable RAID recovery programs but be sure it is one that comes highly recommended.
Believe me, RAID failure is never easy to deal with. It can be costly and it is always inconvenient. There are times when the computer may be down for several days while the issue is being resolved. Luckily, there are ways to recover the data.

Recover Data From A Broken RAID Level 5 or 0 Array With RAID Reconstructor
Runtime's RAID Reconstructor will help you to recover data from a broken RAID Level 5 Array consisting of 3 to 14 drives, RAID Level 0 Array (Striping) consisting of 2 drives.
The Pros and Cons of RAID Recovery Software for RAID Data Recovery
The purpose of raid recovery software is to detect the type of the original RAID array and in some instances, still allow for fully manual operation. It makes recovery of a raid system as easy as a single disc system. Many of the raid software programs are able to detect the type of raid array and go to work recovering the data that has been lost. Most raid software also allows you to back up the information before you fix it.
Recovery for RAID 5 - A Quick Guide
When RAID 5 is implemented, redundant information is used across an array of discs which would leave one to assume that if information is lost from one disc, it is obtainable from another but that is not the case. Information can and is lost from RAID 5 arrays but the good news is that the information is recoverable.
RAID recovery for Linux Systems
As most people realize, dealing with Linux issues is not the same as dealing with Windows or other systems. The same is true when you encounter RAID issues and need to use Raid recovery for your Linux.
Read This Before Attempting to Recover Your RAID 0 Data
Most RAID recovery systems use an algorithm where an exhaustive scan of the drive is performed to locate lost volumes. It recovers data from corrupted RAID configuration, failed/ bad Controller card, damaged/ deleted/ corrupted volumes even from initialized disks. In the case of RAID 0, the information is not repeated on another disc so it is vital to be able to recover all of the information that was lost.
