Recover RAID
RAID Recovery is a job done to recover files lost on a RAID system due to failure or malicious attacks. RAID recovery is necessary whenever files become unavailable and cannot be accessed by normal means.
The RAID system is one of the most secure data storage technologies on the market, but even with all its levels of redundancy and mirroring it is not immune to data loss let alone a ransomware attack.
Large servers that use the RAID system, tend to store data vital to the entire company, making any failures that directly affect the stored files critical.
Data loss can occur due to logical, mechanical failures, human error or ransomware attack, in the latter case we have a department dedicated to decrypting files affected by ransomware.
Whatever the cause of data loss, they all have a enormous potential to generate damage, sometimes irreparable, to the company. This is why choosing a company that specialises in RAID recovery is extremely important. RAID recovery requires in-depth knowledge of how the RAID level affected by the data loss works.
In any scenario of data loss Digital Recovery is ready to act, regardless of the RAID level, we have a deep knowledge in each of the levels. Count on our services to recover RAID.
Why Digital Recovery?
We have been operating in the data recovery market for over 23 years, with one of our specialities being RAID recovery. Our solutions are unique and can recover RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 0+1, RAID 50, RAID 60, JBOD or any other configuration.
Our technology called TRACER enables us to remotely recover RAID in cases of data loss due to logical failures anywhere in the world. If the data loss was caused by mechanical failures, it is necessary to send the media to one of our labs.
Our labs are equipped with the latest generation equipment and are extremely secure, RAID recovery is done in a room prepared exclusively for this purpose. We offer the emergency recovery mode, in this mode our labs operate 24/7 to reduce the recovery time, and we also offer an advanced diagnosis that is done within 24 working hours.
Confidentiality is a fundamental part of our business, so we have taken care to develop all our solutions based on the General Data Protection Regulation (GDPR), to offer total security for all our customers. We also offer an NDA developed by our experts, but if you want to use an NDA developed by your own company we are willing to review it with our legal team and accept it if necessary.
Rely on the security and performance that only Digital Recovery can offer for RAID recovery.

Answers from our experts
My RAID server stopped working, what should I do?
We have compiled a list based on our many years of experience working with data recovery on RAID systems. Before undertaking any procedure to attempt to recover data from your RAID system internally, please consider these considerations:
- Be confident that the procedures to be carried out will not make the situation worse than it already is.
- In most cases, attempts made by technicians who do not specialize in RAID systems further complicate the data recovery process. Eventually, some of these attempts may make the data recovery process impossible.
- Check if the Backup is up to date. If you do not have a backup, before performing any procedure, the best thing to do is to seek expert help.
- Beware of Rebuild procedure.
Never execute the Initialize command. This seemingly harmless command (initialize) will completely reset all data on the RAID, thus making data recovery completely impossible.
My RAID system data is inaccessible, what happened?
The most common situations that cause data to become inaccessible and data loss to occur in RAID are:
- Physical damage to the RAID controller
- Physical damage to the server system board
- Improper changes to RAID controller configurations
- Problems encountered on one or more disks at the same time
- Problems booting the operating system
- Loss of disk sequential order
- Data corruption on GPT or MBR partitions
- Problems occurring in the Rebuild attempts of one or more disks with problems
- Improper recreation of both the RAID and the logical volume attached to the array
- Problems experienced during an increase capacity process
- RAID was rebuilt or rebooted with a different configuration.
Will replacing the RAID controller bring my data back?
A RAID controller is hardware specifically designed for processing information from the volumes and partitions of an Array. The controller board has among others two main functions: The first of them is to perform all the calculations regarding the data processing and storage of the parity information in the Arrays. The second function is to store the configuration data of the arrays created and managed by the controller itself.
A common technique used by the controllers to protect themselves of problems, is to store the data of the managed arrays in reserved areas in the own disks that it uses to create the arrays.
This way, if a controller presents problems, a new controller can be installed and then execute the necessary commands to read the configuration data stored in the disks of the array avoiding data loss. Normally this region of the disk is known as the DACStore. If in fact the problem is in the controller, because of the protections previously reported, it is very likely that the environment will return to work normally. However, if there is a problem with the information recorded on the disks, the data will remain inaccessible.
How does RAID 5 parity work?
Em um sistema RAID 5 com 4 discos:
- All the information from the first block of disks 1, 2 and 3 will be stored in the first block of disk 4;
- In the second block, the information of discs 2, 3 and 4 will be stored in disc 1;
- In the third block, the information of discs 3, 4 and 1 will be stored in disc 2;
- In the fourth block, the information of disks 4, 1 and 2 will be stored in disk 3;
- In the fifth block of RAID 5 the whole cycle starts again.
In this way the parity will be stored in all the disks at the same time. If one of the disks is damaged, the information of this disk that is contained in the parities recorded on the other disks will be used to reconstruct the data on the new disk that will be placed in place of the damaged disk.
For your knowledge: When creating a RAID 5 system, the available space will be the sum of the amount of disks minus 1. Because the system will use the space of one disk to store the parity.

What you need to know
Can I recover data when two or more RAID disks fail simultaneously?
Certainly it is possible, as there are techniques available to reverse this type of scenario, as in most projects, we can safely change the disk status from defunct to online, in order to clone in isolation as soon as possible, the sectors attached to this problematic disk.
How much does the RAID recovery service cost?
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 objective of this evaluation 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.
Is it possible to perform RAID recovery remotely?
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.
How long does it take to recover RAID?
We understand the disruption and damage a RAID server and storage outage can cause 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 typically takes between 4 to 8 hours. As soon as it is concluded, 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.
