We recover data whatever the cause of data loss

Typical RAID failures are caused by component malfunctions (hard drives and controller cards) or operating and application corruptions resulting in inaccessible and/or corrupted data. Kroll Ontrack has listed the most common RAID data loss causes.

Procedural mistakes in the aftermath of a malfunction, or a failed RAID data recovery attempt, can increase damage. Kroll Ontrack provides tips to avoid typical human errors and explains RAID system failures.
We are experienced in recovering from all RAID levels, including:

RAID 0 RAID 1
RAID 3 RAID 4
RAID 5 RAID 1E
RAID 6 RAID 5E
RAID 5EE RAID 0+1
RAID 10 RAID 50
RAID 51

Contact us to verify your RAID level and configuration.

Case story Sunrise Resort – Failed RAID

The backups at Sunrise Resort were out of date when both drives in a mirrored RAID physically failed, and the configuration information for another RAID 5 set was completely lost. Yet, this business bounced back overnight after a "follow the sun" RAID recovery by Ontrack Data Recovery engineers.

RAID Data Recovery Tips

If you suspect data loss in a RAID array the best approach is to take a step back and assess:

  1. What caused the data loss?
  2. What are the consequences of a permanent loss of the RAID data?

Attempting to recover a RAID system without an experienced data recovery specialist can put your critical data at further risk. When hardware malfunction is a component of the problem, permanent destruction of data can occur with failed recovery attempts. Furthermore, the actions taken immediately after a RAID failure can have significant effects on the ability to achieve a full recovery of the data involved.


Successful RAID Data Recovery

Due to the highly technical nature of RAID recoveries, an important step to take when choosing a data recovery provider is to ensure that the provider has the capacity to take on large and highly complex recovery jobs. Many data recovery providers do not have enough resources or expertise to handle a successful RAID recovery. In most data recovery cases, a first recovery attempt will have the highest success rate. For this reason, hiring an expert in RAID data recovery in the beginning will increase the amount of data recovered.  

RAID Data Loss and Recovery Tips

Volume repair utilities such as CHKDSK, are designed to force file systems into a consistent state. While this can be useful on single drive systems with light corruption, in most cases, inconsistencies in a volume stored on RAID storage are a result of problems at the RAID level (i.e. out-of-sync drives, bad rebuilds etcetera.). Running CHKDSK in these scenarios can cause damaging irreversible changes to the file system structures.
  1. Never replace a failed drive with a drive that was part of a previous RAID system; always zero out the replacement drive before using.
  2. If a drive is making unusual mechanical noises, turn it off immediately and get assistance. Leaving a mechanically failing drive powered on increases the likelihood of further damage, significantly reducing the chances of a full recovery.
  3. Have a valid backup before making hardware or software changes.
  4. Label the drives with their position in a RAID array before removing them from your system.
  5. If a RAID system fails in the middle of a rebuild process, do not run further rebuild attempts.
  6. In a power loss situation with a RAID array, if the file system looks suspicious, is un-mountable, or the data is inaccessible after power is restored, do not run volume repair utilities.

RAID Data Recovery Causes

Kroll Ontrack has success in recovering data from virtually all RAID failure scenarios, including:

Human error - Reformat, reinstall and volume overwrite. Proprietary tools allow us to rebuild the RAID virtually, mask out the new active data and repair the original underlying volume to access lost data.


Power issues - Power failure/loss, power cycling and power surges can cause significant issues to RAID systems. RAIDs already running in a degraded state are particularly vulnerable, as power issues can cause out-of-sync drives to be reincorporated into the array. In these cases, Kroll Ontrack has the tools and expertise to map the data and logically rebuild the RAID in the degraded state, before virtually recreating the out-of-sync drive in order to extract the required data.


Mechanical issues and failed rebuilds - Individual drives in RAID systems are subject to failure, as are any hard drives. Once a RAID is running in a degraded state, the workload of the remaining drives increases significantly, particularly during rebuild processes that require much more intensive read/write activity than that to which a normally functioning RAID is subjected. In many cases, this can lead to further drive failure and subsequent RAID failure. Kroll Ontrack has the Clean Room 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.
