Recover files RAID 0

We can act on any scenario of data loss in RAID systems.

RAID 0 is based on the synchronised 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 performance and security when 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, as 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 disk fails the stored data can be affected and become unavailable.

Why Digital Recovery?

Digital Recovery works in data recovery since 1998, with time and experience we have specialized in data recovery in 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 Acrópolis).

We have the ability to act in cases where other data recovery companies have classified as irreversible, we can do this because we have a unique and proprietary technology that we call Tracer. 

With Tracer we generate differentiated results in data recovery in large datacenters, 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 also operate in the area of data recovery.

In case your data is stored on any 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 your case, please consult our department 24×7.

If you require, we can also provide you with a Non-Disclosure Agreement (NDA) in a language of your choice. It is important to mention that our NDA is already adapted to GDPR. Please speak to one of our experts about this.

Being fully aware of the existing levels of pressure and urgency in data centre and cloud computing environments, we also offer a 24×7 emergency service. This type of service provides our customers with the possibility of performing services 24 hours a day, 7 days a week, 365 days a year.

Answers from our experts

What are the main reasons that cause data loss on RAID 0?

RAID 0 has no redundancy and this leaves stored data vulnerable, as any disk that stops working prevents access to files. Here are the main issues that can lead to data loss on RAID 0.

Configuration Issues

  • Loss of Array data;
  • Deletion or change in the RAID controller settings;
  • Exclusion or change of the Array volumes;
  • Loss of the sequential order of the disks.

Logical Problems

  • Deletion or corruption of data on partitions;
  • Formatting drives or partitions;
  • Overwriting information;
  • Formatting followed by reinstallation of systems;
  • Problems booting the system;
  • Dissynchronization of data from one HD to another.

Physical Problems

  • Burns or problems occurring on the RAID controller;
  • Burnout of electronic circuits;
  • Burn in of reading heads;
  • Breakdown of reading heads;
  • Damage to the disk surface (HDD platters);
  • Bad Blocks – Defective Sectors;
  • Natural wear of the media;
  • Scratches and scratches surface;
  • Scratches and scratches serious;
  • Braking of the motor bearings;
  • Motor burn-out;
  • Problems caused by falls or impacts;
  • Problems related to Servomechanism area;
  • Firmware problems;
  • Problems with water or other liquids.

Will replacing the RAID controller bring my data back?

RAID controller is a 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 from 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.

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

While RAID 0 is based on synchronised 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.

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.

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

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.
