Recovering Data from RAID 5 Server

Possibly the most common RAID configuration, RAID 5 provides excellent fault tolerance with only a marginal cost in performance and efficiency compared to other RAID levels. If one disk fails in a RAID 5 configuration, the rest of the array can continue to operate with no data loss, though performance will degrade severely and the entire array will become vulnerable.
RAID 5 is one of the most versatile RAID configurations. All the various aspects such as performance, efficiency, and fault tolerance are fairly balanced, which makes it an attractive option for a wide variety of purposes.
RAID 5 is commonly used in web servers, file and application servers, e-mail and news servers, database servers, Intranet servers, and home use.
We treat server and RAID recovery jobs as high priority cases. We realize the importance that these platforms tend to have, and many businesses depend on their servers as they are an integral part of their operation.
Our RAID recovery services have been developed through many years of experience, innovative methods, and the high standards to which our clients have become accustomed.
We are proud to be the data recovery service of choice for many IT professionals and businesses.

RAID 5 Data Loss

Although RAID 5 confers some protection against data loss, it is still a relatively common occurrence.
One of the ways that data loss can occur is in the case of multiple disk failure. Only one disk can fail in a RAID 5 setup without repercussions on data integrity. If two disks simultaneously fail, then data recovery becomes a necessity. Two disks can fail if they are attached to one faulty bus, or as a result of a power surge. Usually, there is some sort of an inciting event that causes one disk to fail, and the same event can cause another disk to fail simultaneously.
Some common causes of RAID 5 data loss are:
■ RAID Controller Failure
■ Lost, Damaged, or Corrupted RAID Array Configuration
■ Accidental Formatting
■ Intermittent Drive Failure
■ Incorrect Drive Marking
■ Rebuild Errors
■ Addition of an Incompatible Drive
■ Hardware Conflict

What to Do If Your RAID 5 Array Fails?

  • ■ Do not reboot: Simply power down the server/computer and the array. Rebooting can cause serious damage when a RAID 5 array fails.

    ■ If you suspect mechanical failure, power down the array immediately: If a drive is making an unusual noise, such as clicking or grinding, power it off as soon as possible. Continuing to run a physically failed drive can cause irreparable damage to the platters where data is stored.

    ■ Do not run defragment or volume repair utilities on suspected failed drives: Utilities such as chkdsk, scandisk, and fsck are generally not intended for RAID repair. They are designed to solve very specific problems relating to the filesystem, and unless you are sure you have these problems, you should avoid running them at all costs. These operations involve moving and writing a lot of data, which can make the damage far worse.

     ■ Furthermore, the kinds of problems that these utilities are meant to fix can often exhibit themselves in cases  where the actual cause of the original problem is different. Running these operations can be very dangerous!

    ■ Label the positions of all drives in the RAID array and mark the one that failed: People panic when they lose data, and in attempting to fix the situation, it happens surprisingly often that they will mix up the order of the drives or forget which ones failed. This is understandable - data loss can be highly stressful. But it can make data recovery more difficult when we lack such information, so please take care to label your drives as soon as you can.

     ■ Please note that drives in a RAID array are numbered starting from 0.

    ■ Log the events you observed that led to the failure: This will provide valuable information that will make the data recovery effort more likely to succeed.

     ■ Also please log all attempts you have made, if any, to remedy the problem and any consequences you observed.


    ■ Do not change the order of the drives in an array: When the situation is already dangerous, you run an extremely high risk of data loss if you alter the RAID configuration in any way.

    ■ Do not swap another disk into the array: This can also become catastrophic if done incorrectly. New disks have to be completely zeroed out before insertion, and it is crucial to follow the manufacturer's instructions when swapping. It is highly advisable not to perform this operation in any potential data loss scenario.

    RAID-5 Recovery

     Generally, data recovery from a RAID system is feasible, but the knowledge, time and resources that are required make RAID-5 recovery the most technically demanding form of data recovery. RAID manufacturers differ vastly in their designs of the internal components and circuitry of their systems, and an in-depth knowledge of these designs is crucial for successful data recovery. But because manufacturers do not disclose this information, RAID recovery techniques require many years of development in order to determine which ones are the most effective.
    RAID 5 presents some benefits and difficulties for the recovery process. On the one hand, parity information, if available, can speed up the recovery process significantly. However, the highly distributed nature of data storage in a RAID 5 system does tend to make RAID 5 recovery a complicated process in comparison to some other RAID configurations.
    After receiving your RAID system, we will quickly assess the extent of the damage and connect you with an expert who can guide you on the best course of action for your specific situation. Our recovery engineers will work around the clock to recover your critical data. If the data cannot be recovered, we do not charge a recovery fee. We can recover data from all servers, home computers, direct-network RAID storage devices, NAS devices, SAN systems, and a wide variety of other storage environments. Our engineers have performed countless successful RAID recoveries over their decades of combined experience.
