Recover RAID 6

We can handle any data loss scenario in RAID systems.

Recovering RAID 6 is a delicate job that requires the best professionals to handle the best and newest technologies for data recovery in RAID System on the market, with the goal of resuming the Servers and Storages affected by data loss.

The RAID 6 system is an evolution of RAID 5. The main difference is that instead of using only one disk for redundancy, 2 disks are used.

In other words, in this system, even if two disks are physically damaged at the same time, the system will still continue working. But the available space will be the total of disks minus 2.

So if you set up a RAID 6 with 7 disks, the space you have available will be the total equivalent of 5 disks.

This system is used in extreme security situations. The RAID 5 system allows only one disk to go bad. If two disks go bad at the same time, or a second disk goes bad before the first disk has finished rebuilding, the system will stop.

The RAID 6 system allows the same performance as RAID 5, but with greater security. When creating RAID 6, the available space will be the sum of the number of disks minus 2. Because the system will use the space on two disks for storage and parity control.

And if data is lost on RAID 6, even though it is difficult, we at Digital Recovery can recover the files.

Through reverse engineering and full understanding of the algorithms used in RAID controllers, we can recover data in the vast majority of cases of data loss in RAID systems.

Answers from our experts

What are the main causes of data loss in RAID 6?

There are three main causes, which are: configuration problem, logic problem, and physical problem.

Configuration problems:

  • Array data loss
  • Deletion or change of RAID controller settings
  • Array volumes deleted or changed
  • Loss of the disks’ sequential order

Logic problems:

  • Deleting or Corrupting Data on Partitions
  • Formatting drives or partitions
  • Overwriting information
  • Formatting followed by system reinstallation
  • System booting problems
  • Data desynchronization from one hard drive to another

Physical problems:

  • RAID controller burn-in or problems
  • Burnout of electronic circuits
  • Burn in read heads
  • Read head breakage
  • Damage to the disk surface (HDD platters)
  • Bad Blocks
  • Natural Media Wear
  • Surface scratches and scuffs
  • Serious scratches and scuffs
  • Motor bearing seizure
  • Motor burn-out
  • Dropped or impacted problems
  • Servo Mechanism area related problems
  • Firmware problems
  • Water or other liquid problems

Will replacing the RAID controller bring my data back?

RAID 6 is designed to be the evolution of the predecessor RAID levels, increasing security and performance, but it is still not immune to failure. Let’s look at the positives and negatives of this RAID level.

Positive points – Fault tolerance of 2 disks at the same time; performant read time.

Negatives – 50% reduced storage level; Performance problem if a disk fails.

Can I preselect the most critical files to be recovered first?

Yes, in many situations it is possible to recover data from a RAID server or storage remotely. For more information about this recovery modality, please contact us through our support channels, which are available 24x7x365.

The RAID 6 system is a type of Redundant Array of Independent Disks (RAID) that offers enhanced data protection using double parity. This means that


What you need to know

We understand the disruption and damage that a RAID server and storage outage can cause to your business. With that in mind, we have created a 24×7 department that is dedicated to assisting customers who have extreme urgency in recovering data from RAID systems.

As soon as disks from a RAID server or storage enter our lab, the advanced diagnostic process begins immediately. The advanced diagnostic process usually takes between 4 to 8 hours. As soon as it is completed, the customer will be informed about the possibilities of data recovery, the amounts involved, as well as the estimated time for recovery.

The average time for data recovery in servers and RAID storage at Digital Recovery is approximately 36 hours, but in some cases, projects have been solved in less than 12 hours. Depending on the complexity of the problem and the type of solution to be adopted, the time for data recovery may extend for a few days, but at all times a specialist will be in contact with the focal point of the customer, to report in detail on all movements made.

Regardless of the number of disks that will be allocated in the array, the system will use the space equivalent to one disk for parity, ie, to get the net space, just multiply the capacity of the disks by the number of disks subtracting one.

Example | Considering 5 disks of 3 TB each, totaling 15 TB of raw space.

Subtracting one disk gives us a total of 4 disks of 3 TB, i.e. 3 TB x 4 = 12 TB

The first action to be taken is to contact the manufacturer or technical support of your server or storage. They will direct the diagnosis in the best possible way, because through the logs collected, it will be possible to create a coherent and assertive action plan.

If it is not possible to restore the environment either via the manufacturer or via restore of the most updated backup, we can help you solve this challenge in the best possible way.

Because of the many variables involved in a RAID data recovery project, it is not possible to know the final value without performing a detailed evaluation. The purpose of this assessment is to determine:

  • Level of complexity and urgency
  • Real possibility of recovery
  • Time to perform the service

To make an assessment, please contact us through our support channels, which are available 24x7x365.

The Logical Volume Manager (LVM) can be fully recovered, as it is an option for managing logical volumes of a hard disk or RAID in Linux/Unix operating environments.

In some cases yes. Especially when you have an environment with few disks and when you remember exactly the array configurations.

But when you have storage with numerous hard disks, running with multiple volumes, using different RAID configurations and even with Hot Spare disks, even if you have all this documented it will not be an easy task to recreate the array and get it working again.

In the case of Virtualized RAIDs or vRAIDs, even if you have all the configurations noted down, the only possibility of returning the Array is by reading the configurations contained on the disks (DAC Store).

Since we know that a disk failure can drastically impact both the availability and integrity of companies’ strategic data, 24×7 monitoring of the health status of disks is extremely important, as it allows the suspect disk to be replaced even before it actually fails.

The RAID controller management software itself can be used for this type of predictive monitoring.

Through unique technologies Digital Recovery can bring back encrypted data on any storage device, offering remote solutions anywhere in the world.
