Data loss from a RAID can occur unexpectedly, and we understand it can be catastrophic when it does.

If you suspect a RAID array failure, contact the experts at Ontrack Australia to get your data back as quickly as possible.

Unparalleled expertise in RAID data recovery

Recovering lost data from an enterprise RAID system is much more complex than from a simple hard drive.

Ontrack uses advanced techniques to repair, recover and reconstruct data that has become inaccessible. With Ontrack, you'll know exactly what data is recoverable before committing to the actual recovery. 

RAID data recovery experts

All types of RAID systems

Our engineers backed by over 25 years of data recovery research, experience and development, have the knowledge and tools to get your data back. We perform RAID data recoveries on:

  • Any RAID level
  • Any RAID controller, RAID architecture including software-defined storage (SDS)
  • Any hard drive type, make or model
RAID 51  

RAID recovery services

Whether your RAID system has suffered physical damage or experienced a logical failure, we have a range of services to match your specific needs.

In lab

The best recovery option for any type of RAID system, for any situation. This recovery service is provided in our state of the art data recovery lab and specialist cleanroom environment to ensure the safety of your data.



Your RAID data is recovered remotely without your media ever leaving your premises. We connect to your system via the Internet to perform a live recovery. Available when the storage device or system is still operational.


If your RAID system cannot leave your premises, our engineers can bring their recovery expertise to you. This option is only available for emergency service. For onsite data recovery, the storage device or system must be operational.


We offer custom designed recovery solutions for proprietary RAID systems and/or highly complex enterprise level systems. Our R&D team will work with your IT staff to create an emergency solution to retrieve your data.

Common causes of RAID data loss

Each RAID data recovery is unique, but there are a few common causes of data loss:

Human error

Whether it was by accident or malicious intent, data loss from reformatting, reinstalling or a volume overwrite can be overcome by expert data recovery engineers.

Power issues

RAID systems can be affected by loss of power, power cycling and power surges causing loss of data. RAIDs running in a degraded state are especially vulnerable, as power issues can cause out of sync drives to be reincorporated into the array. In these cases, we have the tools and expertise to map the data and logically rebuild the RAID in order to extract the required data.

Mechanical issues

RAID systems are built to withstand individual drive failure, but once a RAID is running in a degraded state, the workload of the remaining drives increases and so does the risk of additional drive failures. Additional drive failures can lead to failure of the RAID. We have the experience required to recover data from failed drives, combined with the logical skills and tools to rebuild and repair file systems from failed or partially rebuilt RAID systems.

Natural disasters

Fire, water, dirt and other contaminants from natural disasters can destroy a RAID array in an instant. Rebuilding file systems from a RAID affected by a natural disaster takes specialist facilities, knowledge and tools to decontaminate the drives and logically rebuild the data. Ontrack has state of the art tools and cleanroom environments to safely recover from physically damaged drives.

The different types of RAID

A RAID configuration, including the number of disks used, determines the type.

As a reminder, RAID stands for 'Redundant Array of Independent Disks' is a storage solution that distributes data across multiple disks that together form a single system. In addition to being less expensive, these devices have a high level of performance and fault tolerance through built in system redundancy.
