Common Reasons RAID Arrays Fail and RAID Data Recovery


I am using a Windows server 2003 with a disk array system. This has a Raid controller as part of the set, and so I installed a pair of disks using a Raid 0 partition system. This worked fine until recently, but there now seems to be a problem with one of the drives in the array. Because I have a busy work schedule that often means that I have to leave data overnight, I have a program of scheduled restarts, which means that the computer saves all of this data, and then reboots. Rather than reboot and carry on as usual, the computer will suddenly boot up again and again. It has got to the point where it won’t stop rebooting, and I can’t access either the drives, or the data which has already been saved onto the server. This means that I can’t recover the information from the server. I have looked on BIOS< which is suggesting that here is a corrupt sector on the first drive.


I need some help with a set of 3 WD hard drives which I have been trying to recover. They are set up into a RAID 0 formation. Something happened last week, and when I tried to open one of the files, the computer suddenly tried to reduce the size of the array. I don’t know what has happened to cause this, but I am concerned that there is data on the drives that I won’t be able to recover because of this problem. I am not running drives which are too large for the server, and in fact they have been connected to the computer for several months. I haven’t made any significant changes to the array, only saved data to it, and I can see that at least one of the drives is nearly full, although the other seems empty. I tried to remove one of the disks to lighten the load of the array, and the computer now says that the disks are not found, and I need to do a reboot.

Common Reasons RAID Arrays Fail and RAID Data Recovery

In many cases, the reasons businesses or organizations opt to use RAID systems is to avoid the devastating results of lost data. Despite the overall reliability of RAID Arrays, they do experience failures from time-to-time. When this happens it can mean lost productivity and expensive employee downtime. Many business owners don’t have the resources to cope with the level of financial loss that can be the result of malfunctioning RAID arrays over a long period of time.

What is a RAID Array?
RAID stands for a Redundant Array of Independent Disks, which in simple terms refers to a group of multiple hard drive disks. RAID arrays offer users a number of advantages, including increased performance and reliability. When a RAID system is utilized, data is saved in several locations at one time, which can mean data is saved even in the instance of an error or failure. Although RAID arrays are a reliable way to store data, they are still subject to failures, which makes the services of a qualified data recovery service necessary.

Common Causes of Failure?
Although RAID systems are designed to be fault-tolerant, they are by no means completely resistant to fault. Many types of RAID systems can withstand the failure of one hard drive, but problems come into play when more than one of the hard drives endures an error or failure. Using a RAID system can often be problematic, because users have the common misconception that failure isn’t possible, so they don’t take the time to back-up data. Despite the solid reputation of RAID systems, all data should be backed-up, in any circumstances.

Commonly, RAID systems experience failures because of problems that affect traditional hard drives, including physical damage, such as motor damage and platter damage, as well as electronic damage, that occurs from situations such as power surges. RAID systems are also susceptible to failure due to viruses, logical problems and human error.
In addition to the causes of failure shared by RAID arrays and regular hard drives, RAID arrays can be vulnerable to additional problems because of the complexity of the system. This includes lost server registry configurations, RAID controller drive failures and multiple drive failures.

How to Recovery Data from a Failed RAID System
A RAID system is much more complex than a standard hard drive, and requires a high level of expertise to recover data. Many IT departments are not equipped to deal with the failure of a RAID array, and it often requires the services of a specialist in the field of RAID recovery.
Again, because of the complexity of these systems, an individual should never try to recover data without the help of a professional service, because it can lead to the permanent loss of data.

It’s important to find a data recovery service that offers state-of-the-art equipment, a secure facility and a long history of successfully recovering data. If a RAID array does experience a failure, it can be an incredibly stressful time, and it’s important to remedy the problem as quickly and effectively as possible.
