Recover RAID 0
RAID 0 is based on the synchronized distribution of information among several disks, in other words, the system causes all stored files to be written to all disks at the same time.
The RAID system is designed to increase the performance and safety of writing and reading data on a disk.
The controller in RAID 0 divides all files into multiple blocks (stripes) on all disks in the array, the data is written sequentially. This makes RAID 0 extremely fast, because it distributes the writing and reading of the stored data among several disks.
RAID 0 is the most performant RAID levels, besides not compromising the storage capacity of the disks used, at this level only 2 disks are required for operation.
But even if there is a large increase in performance, RAID 0 is not fault tolerant, if any of the disks fails the stored data can be affected and become unavailable.
Why Digital Recovery?
Digital Recovery has been working in data recovery since 1998, with time and experience we have specialized in data recovery on RAID systems. We have a division exclusively dedicated to meet cases of high complexity, as is the case of data loss on RAID 0.
This business unit is known as Data Center Recovery Services and specializes in recovering RAID (0, 1, 10, 5, 50, 6, 60, vRAID, RAID-Z and JBOD), Storages (NAS, DAS and SAN) with iSCSI Host Channel, SAS and FC (Fibre Channel), 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).
We are able to act in cases where other data recovery companies have classified as irreversible, because we have a unique and proprietary technology that we call Tracer.
With Tracer we generate differentiated results in data recovery in large data centers, we can execute this solution remotely in most cases, thus drastically reducing the time of the recovery process.
We are a Brazilian company with a branch in Germany. Other partnerships for information exchange and technology sharing are made between companies in countries such as the United States, Russia, and Ukraine.
In addition to providing services to governments, financial institutions, and small, medium, and large companies, Digital Recovery also provides services to other companies that are also active in the area of data recovery.
In case your data is stored on a device located outside the countries where we have laboratories, we have the technology that enables us to assess and recover your data remotely. If this is the case, please consult our department 24×7.
Should you need it, we can also provide you with a Non-Disclosure Agreement (NDA) in a language of your choice. Please talk to one of our experts about this.
Being fully aware of the existing levels of pressure and urgency in data center and cloud computing environments, we also offer a 24×7 urgency service. This type of service provides our customers with the ability to perform services 24 hours a day, 7 days a week, 365 days a year.
We are always online
Please fill out the form, or select your preferred contact method. We will contact you to start recovering your files.
Customer experiences
What our customers say about us
"We had a serious issue following a NAS server power outage in Raid 5. I immediately contacted DIGITAL RECOVERY. After a few days of hard work the issue was resolved."
"One of our RAID servers had stopped. After several attempts without fixing the problem we found DIGITAL RECOVERY and 5 hours later, at 4:00 am, the data was recovered."
"We referred DIGITAL RECOVERY in a special case (data loss) in a storage RAID 5. Digital Recovery recovered 32 million files and the customer was extremely satisfied."
"Without any doubts the best data recovery company. Digital Recovery contact details will always be saved on my cell phone, as I will inevitably need it again."
"The quality of the service is excellent. The attention given to the service is gratifying and the feedbacks that are given leave us calm, knowing that we can trust in the work and dedication."
Customer since 2017
"Great company, they saved me from a big problem!!! I recommend them, what a quick service, my thanks to the Digital Recovery team for the attention and speed in solving the problem! Awesome!"
"The second time I count on the agility and professionalism of the Digital Recovery team, they are very experienced and agile. I recommend them to everyone"
They helped me recover some data that I had thought was lost. I had a great experience with the team for their calmness, agility, and transparency.
Answers from our experts
What are the main reasons that cause data loss on RAID 0?
RAID 0 has no redundancy and this leaves the stored data vulnerable, as any disk that stops working prevents access to the files. Here are the main problems that can lead to data loss on RAID 0.
Configuration Problems
- Array data loss;
- Deletion or change in RAID controller settings;
- Exclusion or change of the Array volumes;
- Loss of the sequential order of disks.
Logic Problems
- Deleting or corrupting data on partitions;
- Formatting drives or partitions;
- Overwriting information;
- Formatting followed by reinstallation of systems;
- Problems booting the system;
- Dissynchronization of data from one hard drive to another.
Physical Problems
- Crashes or problems occurring on the RAID controller;
- Burnout of electronic circuits;
- Burnout of read heads;
- Breakage of read heads;
- Damage to the disk surface (HDD platters);
- Bad Blocks – Defective Sectors;
- Natural wear of the media;
- Scratches and scratches surface;
- Scratches and scratches severe;
- Locked motor bearings;
- Motor burnout;
- Problems caused by falls or impacts;
- Problems related to the Servomechanism area;
- Firmware problems
- Problems with water or other liquids.
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 controllers to protect themselves from problems is to store the data from the managed arrays in reserved areas in the disks that are used to create the arrays.
This way, if a controller has a problem, a new controller can be installed and then execute the necessary commands to read the configuration data stored in the array disks, avoiding data loss. This region of the disk is usually 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 function normally again. However, if there is a problem with the information on the disks, the data will still be inaccessible.
Can I preselect the most critical files to be recovered first?
Yes, you can send us a list of the main files and folders that urgently need to be recovered, so we can focus on these specific files and recover them as a priority.

What you need to know
What are the differences between RAID 0 and RAID 1?
While RAID 0 is based on synchronized distribution across all disks in the array, with a focus on performance, RAID 1 has the main focus on data security by applying disk mirroring, i.e. all data stored on one disk is written to another.
Can I recover data when two or more RAID disks fail simultaneously?
It is certainly possible, as there are techniques available to reverse this type of scenario, as in most projects we are able to safely change the disk status from defunct to online in order to clone the sectors attached to this problematic disk in isolation as quickly as possible.
How much does RAID 0 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 make 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.
