We have developed unique solutions that can recover data on RAID 10
Recover files RAID 10
RAID 10 is nothing more than the junction of RAID 1 with RAID 0, it differs from RAID 0+1 in its structure. RAID 10 combines the performance of RAID 0 and the security of RAID 1, making it one of the most performant and secure RAID levels.
At this level the storage can contain numerous disks, and each disk will have another identical disk (mirror) in the same array. In other words, a RAID 0 is created and for each disk of RAID 0 is created a mirror with the same information.
If on the one hand, RAID 10 we have the same performance of RAID 0 and RAID 1 security, it also takes its toll. The disadvantage of this system is that it will always take half the disks – 50% of available storage – to generate data redundancy, ie if you create an array with 10 disks, you can use the space equivalent to only 5 disks. The other 5 disks will be for the exclusive use of the controller and will be used for generating data redundancy.
Even at this level the risk of data loss is not zero, companies that use this RAID level demonstrate the value that their data have, in this case, any data loss can become a major problem.
There are many reasons that can lead to data loss on RAID 10, the most common occur due to configuration failures, logical failures, mechanical failures, human error and, perhaps the most serious of all, ransomware attacks.
In any of these scenarios Digital Recovery is able to act, with our 25 years of experience we have recovered several RAID levels, including 10.
Why Digital Recovery?
Digital Recovery is a company specialized in recovering RAID of all levels. We created a dedicated division to exclusively serve highly complex environments.
This business unit is known as Data Center Recovery Services and specializes in recovering data from RAID systems (0, 1, 10, 5, 50, 6, 60, vRAID, RAID-Z and JBOD), Storages (NAS, DAS and SAN) with Host Channel iSCSI, SAS and FC (Fibre Channel) from various manufacturers such as HP / HP, Dell / EMC and IBM / Lenovo, databases (Microsoft SQL Server, Oracle, MySQL, PostgreSQL, MariaDB, Firebird, DB2, Informix, Caché and Btrieve) and virtual machines (Microsoft Hyper-V, VMware, Citrix XenServer, Proxmox and Acropolis).
Even if you’ve received a negative diagnosis from a data recovery company, we are still happy to look into your case.
We have developed software and hardware technologies that enable us to act with precision and agility in advanced diagnostic and data recovery processes. The creation of technologies – many of them proprietary and exclusive – has kept Digital Recovery on the cutting edge.

Soon after a new wave of LockBit 2.0 ransomware attacks, many companies saw their business come to a standstill because of data locked out of encryption. Here is a case of decryption for one of them.
We received a contact from a company that said it had suffered an attack and was unable to continue its activities. When they arrived at their offices after the weekend, they realised that a large part of their data was inaccessible.
One of the largest River Logistics companies in Latin America contacted us to decrypt files after a Quantum Ransomware attack.
There has been a wave of attacks by the Quantum group targeting several different companies. Small, medium and large companies have been targeted. In this case a large Fluvial logistics company in Argentina was the victim.

Why is data lost in RAID 1?
- After 2 years of continuous use of a RAID 1, one of the disks fails with a bad block problem. Because this disk is no longer in normal use, the controller or the array management software will discard any attempt to write or read to this disk. The system will also warn the user about the problem so that he can replace the failed disk quickly. This is exactly where most of the problems occur. Because the system continues working normally, because one of the disks is still 100% functional, the user does not pay attention to the warning and continues using the machine. Six months later, the second disk fails. But this time instead of only presenting failures caused by bad blocks the RAID disk is completely inaccessible. When trying to solve the problem by connecting the disks on another computer or sending to a technical assistance the only disk that will still be accessible is the disk that stopped first (6 months ago), because even presenting bad blocks it may still be possible to access some information, but from 6 months ago.
- Because most RAID 1s are mounted on ordinary machines and without the infrastructure (Enclosure and RAID Controller) required for RAID systems, they are much more susceptible to failure. Because of this, another problem can happen when one of the disks presents problems in the cable or connection to the motherboard. Although the disks are without any problems, a bad contact in the connection cable of one of them interrupts communication. The Array management system warns the user, but he does not notice. As there is 100% redundancy of the data on another disk, the machine will continue working normally and without performance problems. Some time later, when doing maintenance on the computer, the cables are disconnected and reorganised. In this maintenance there is a risk of reconnecting the HDs in different ports and confusing the system. Once two disks are connected in RAID 1 again the system will identify that they are not equal, because there is enough time that one of them was disconnected from the RAID. At this point the system will update the information from one disk on the other. As the disks were connected on different ports, the system can simply copy the disk with old information on the disk with new information.
- Following the same line of problems mentioned above, when one of the disks of RAID 1 fails and the user continues to use the system, there is the possibility of data loss if for some reason the user recreate the array. By doing so, the system will identify that the disks contents are not exactly equal. At this time the system will copy the information from the first disk to the second and data overlapping may occur.
Can I pre-select the most critical files to be recovered first?
Yes, you can send us a list of the main files and folders that need to be recovered urgently so we can focus on those specific files and recover them as a priority.

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.
What is Degraded RAID? How do I know if my RAID is degraded?
A Degraded RAID is when one or more redundancy disks have stopped working. Depending on the type of Array this will imply loss of performance. The surest way to know if the RAID is degraded is by accessing the controller management software. On IBM/Lenovo servers this software is called MegaRAID Storage Manager. Another way to see it is to observe if any orange led is lit on the disks belonging to the array in question.
How much does RAID data 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 purpose of this assessment is to determine:
- Level of complexity and urgency
- Real possibility of recovery
- Time to perform the service
To perform an assessment, please contact us through our support channels, which are available 24x7x365.
Is it possible to recover data from a RAID 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.
Is it possible to recover an environment containing LVM?
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.
If I recreate the Array with the old configurations will my RAID return to working as before?
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, used different RAID configurations and even with Hot Spare disks, even if you have all this documented will not be an easy task to recreate the Array and it will work again. In the case of Virtualized RAIDs or vRAID even having all the configurations noted the only possibility of returning the Array is by reading the settings contained on disks (DAC Store).
