RAID Data Recovery

Whether your device has suffered physical damage or undergone a logical failure, we offer you a range of services to match your specific needs.

Our experts are on-hand and will respond to your issue immediately. From assisting with troubleshooting to onsite recovery, our wide range of expert recovery options will ensure you receive the very best solution to solve your RAID data loss problem.

What To Do When Experiencing RAID Failure

Nas Unit with Fire Damage

Before doing anything, answer the following questions:

  • What specifically happened/ how did the event unfold?
  • What data is lost?
  • How critical/valuable is this data?
  • Do I have a backup or other means of getting this data back?
  • What are the financial implications of this data loss?

The answers to these questions will be crucial to determining the data recovery next steps.

Often you only have one chance to get the system back up and running and recover stored data, so gathering as much information as possible is important.

Stopwatch

Stop!

The majority of avoidable data damage happens in the first sixty minutes after a failure, the so-called golden hour, due to human action.

Here's a few examples:

  • Swapping wrong disks in the RAID configuration (RAID 0, RAID 1, RAID 5, RAID 6, RAID 10...).
  • Raid corruption by replacing incorrect RAID controller.
  • Forcing disks online.
  • Initialising wrong disks.
  • Failed rebuilds.
  • Restores from incomplete backups on the same system.
  • Performing a VMware Storage vMotion when the storage system has failed.

In all these cases it is essential that all activities are stopped and no further changes are written to the original configuration of the system and the individual storage devices itself. A RAID is the base of most servers, Network Attached Storage (NAS), and Storage Attached Network (SAN). It is often not obvious when the RAID is the underlying cause of a problem.

Often you only have one chance to get the system back up and running and to recover stored data. It is essential to reach out to data recovery experts, Ontrack Engineers will help you to determine how to proceed and will inform you about chances, risks and possible next steps.

Symptoms of a broken RAID

Many symptoms can hint there is a RAID array failure. 

Obvious symptoms:

  • Error messages
  • Beeping sounds / alarms
  • (Red) light on the server
  • Drives making noises

Less obvious symptoms:

  • Data corruption
  • Database corruption
  • Unable to access files
  • Logical drives disappearing
  • Lost connection to server, volume, share, LUN
  • Volume down
  • System speed
  • System no longer accessible

Common RAID Data Loss Causes

HDD Icon
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 failure can lead to failure of the RAID. We have the cleanroom environment and expertise 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.
Power Icon
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, our teams have the tools and expertise to map the data and logically rebuild the RAID in order to extract the required data.
Water Icon
Natural Disasters
Fire, water, dirt and other contaminants from natural disasters can destroy a RAID in an instant. Rebuilding file systems from a RAID affected by a natural disaster takes specialised 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.
Human Icon
Human errors
Whether by accident or completed with malicious intent, data loss from reformatting, reinstalling or volume overwrite can occur throughout any organisation of any size. However, with the knowledge and expertise of Ontrack, even the most damaging human error can be conquered by expert data recovery engineers.
Cyber Attacks Icon
Cyber attacks
Whether conducted through computer information systems, computer networks, infrastructures, or personal computer devices, unwelcome attempts to steal, expose, alter and/or destroy sensitive information through data breaches and cyber attacks cause significant data loss. Ontrack has the tools and expertise to safely recover your data from a malicious cyber attack.
Gray-Raid 6 Ransomware Attack
Ransomware attack
A form of malware, malicious software that encrypts a victim's files, Ransomware attacks prevent an individual from accessing their computer, or any data stored on it. This form of attack can result in the computer itself becoming locked, or the data on it to become stolen, deleted, or encrypted. Ontrack’s expert data recovery engineers can recover data from a ransomware attack.

RAID Recovery Tips

  • Never replace a failed hard drive with one that was previously part of a RAID system – ensure you completely erase the replacement drive before use.
  • If a drive makes unusual mechanical noises, turn it off immediately and seek help.
  • Obtain a bit-by-bit image of the hard disks before making any changes to hardware, software, or performing a RAID rebuild.
  • Label the disks with their position in a RAID array.
  • Do not run recovery programs on suspicious volumes. Volume repair tools, such as CHKDSK are designed to force file systems to a consistent state. This can be useful for a single disk system with simple errors. On a RAID system, inconsistency of a volume can usually be traced to problems with the RAID (i.e. out-of-sync disks, failed rebuild, etc). Using CHKDSK in such scenarios can result in harmful and irreversible changes to the file system.
  • Do not run defragmentation programs on suspected failed disks.
  • Do not run volume recovery programs in cases of a power failure on a RAID array, when the file system looks suspicious or is un-mountable, or the data is inaccessible after power is restored.
