RAID Recovery Capabilities

With over 12 locations nationwide, Sherlock Data Recovery services deliver fast and reliable results for recovery on all RAID levels.

Why People Choose RAID

A RAID uses multiple disks to increase storage capacity for systems and have a redundant way to store data. Information is stored in different places on multiple hard disks which gives it fault tolerance to survive one or many disk failures. Individuals and businesses flock to this technology as they believe it is the safest way to store their critical files.

Unfortunately, RAID arrays are still susceptible to data loss. The distribution method of data among the disks and the mechanical nature of the disks makes them vulnerable to failure. In some cases, their resiliency works against them as one failed disk may go undetected before the rest of the disks begin to fail.

RAID Levels

Our experienced engineers can successfully recover data from all RAID levels including:


Utilizes a striping storage method to break down and store information into fragments across the disks in the array. Our engineers use advanced tools to recover data from striped storage.


Uses a mirroring technique for writing data so each disk holds the same information. We can recover files from your RAID 1 from any data loss scenario.


Writes to each of its disks simultaneously and has a parity function distributed on each disk for fault tolerance. Engineers have decades of experience treating all types of servers and RAID arrays.


Stripes data across disks with two distributed parity blocks per drive. Parity blocks allow RAID reconstruction after a single drive failure. We develop innovative recovery techniques for RAID 6 and all other arrays.


The nested configuration that includes mirrored drives in each RAID array and striped data across every set. They can sustain one hard drive failure per set. Engineers are experts in recovering mirrored and striped data from all systems.


Combines striped data of RAID 0 and has a parity disk on each set as a RAID 5. A minimum of six drives is required. We pioneered many successful recovery techniques for RAID 50.

Causes of RAID Failure

While RAID configurations have higher redundancy and fault tolerance, in many cases, one disk failure can affect the entire configuration. Your array can experience data loss due to a variety of scenarios. Common types of RAID failures include:

  • Inadvertent data deletion
  • Formatted Partitions
  • Virus Infection
  • File System Corruption
  • Controller Failure
  • Incorrect RAID rebuilds
  • Single or Multiple Drive Failures
  • Power Surge

Our secure recovery process begins with a free diagnostic review of your RAID (HDD/SSD). Engineers then make an image of the disks and scan and analyze the file system, RAID, and SAN metadata.

After a quote is given and approved, engineers will repair damaged RAID members and image them to work from a copy of the media so the device stays in its original state. They will then perform RAID assembly, SAN assembly, file system repair, or database repair (SQL, Exchange, Oracle, etc.) if needed. Engineers will then extract the data and send it back to clients on secure storage media.

Secure Data Recovery Services offers industry-leading success rates for data loss from RAID 5, 0, 1, and all other configurations.

What to Do When Experiencing RAID Failure

When experiencing a RAID failure, immediately shut down the system and call a professional. There are several actions you should NOT take when your device fails:

  • Attempt to reset the RAID
  • Re-insert and force online RAID members
  • Try to repair file system by running checkdisk or fsck
  • Read from drives with SMART errors or bad sectors
  • Run software-based recovery programs

These actions will cause damage to the data, destroy redundancy, damage file systems, and irreversibly damage the drives. Call Secure Data Recovery for experienced RAID data recovery services at 1-800-388-1266.

Questions and Answers

Does my RAID configuration level affect the data recovery process?

The engineers at Secure Data Recovery are experts in treating any type of RAID array. While configuration options can make recoveries more difficult depending on the failure itself, we regularly work with RAID 1, 0, JBOD, nested RAID and many other arrays. Our overall success rate for RAID recovery is 90%.

Can you remotely recover data from my RAID?

In some instances, yes. We have an advanced set of services for RAID arrays, but we can’t remotely repair a RAID if it has been physically damaged. Those types of data loss scenarios must be treated in our certified lab.

How much does a RAID recovery cost?

Costs vary between cases due to factors like RAID configuration level, number of drives, operating system, failure scenario, and size of the files that must be retrieved.

Secure Data Recovery provides risk-free diagnostics for all RAID systems and stands by the company’s “No data, No recovery fee” guarantee. We maintain a fully equipped RAID lab and our engineers can treat any scenario effectively.

Can I use data recovery software to recover my RAID files?

We do not recommend using software for recovery on RAID systems. Many commercial applications are not designed for RAID arrays and can cause serious file corruption. Operating your RAID in a failed state can cause permanent damage and overwrite of files. Secure Data Recovery engineers make a full clone of each drive in the RAID array before performing logical repairs. This ensures the best chance at a full recovery.

Does my operating system affect the RAID recovery process?

Yes, though the file system on your operating system has a greater effect. Many RAIDs use Linux, Unix, Solaris, Windows, or Mac OS. Our team have developed specialized utilities for the file systems associated with these products.

What can I do to ensure a fast turnaround for my RAID recovery case?

Take appropriate steps to limit the damage to your system by turning your server off as soon as you notice failure symptoms. Do not attempt to rebuild a damaged RAID array if you notice error messages or if previous attempts have failed. Keeping the array powered down will increase your chances of a full recovery.

Sherlock Data Recovery offers several turnaround options for RAID data recovery including 24/7 emergency service with an average turnaround of 48 hours.
