RAID Data Recovery

RAID data recovery

DriveSavers provides unparalleled data recovery and digital forensic services for all RAID devices and configurations.

Critical data is often stored on RAID systems because they are considered to be fault tolerant devices. RAID systems can be configured to keep working even when one drive fails so that disks can be “hot swapped” while the system keeps running. However, even this setup of an array of drives is not infallible as it can only offset the failure of a single drive. The problem is that multiple drive failures frequently occur, against which a RAID system alone is defenseless.

RAID Data Recovery Experts

Our certified RAID data recovery engineers have the in-depth knowledge and technical expertise that comes from over 30 years of data recovery experience, allowing us to achieve the highest success rate in the industry. DriveSavers Enterprise Systems Group specializes in recovering data from all operating systems and all types of high-capacity devices including redundant arrays of independent disks (RAID), network attached storage (NAS), storage area networks (SAN) and multi-disk servers. We routinely rescue lost databases, ERP accounting systems, mail servers and other mission-critical data for organizations of all sizes.

Close Affiliations with RAID Manufacturers

Because RAID devices are constructed with unique components and configurations depending on the manufacturer, it is imperative that our data recovery engineers have in-depth knowledge of the various proprietary metadata structures and hardware.

Technical alliances with RAID controller manufacturers have enabled our engineers to develop proprietary techniques, tools and technologies that aid in data recovery from RAID devices based on solid-state drives (SSDs), hard disk drives (HDDs) and more complex hybrid and tiered storage environments. All major RAID manufacturers authorize our data recovery services so working with DriveSavers will not void your original warranty.

State of the Art Cleanroom

Extreme damage and data loss can result if any particulate matter enters an HDD. DriveSavers Certified ISO Class 5 Cleanroom is the most advanced data recovery Cleanroom in the industry. This dust-free, static-free, temperature– and humidity-controlled environment maximizes our data recovery successes on all storage devices by protecting the platters and electronic components on the drives from “killer particles” while they are open and vulnerable to damage.

Why RAIDs Fail

There are four general categories of failure: hardware RAID failure, human error, software RAID failure and application failure.

RAID Hardware Failures

At DriveSavers, we recover RAID data from hard disk failures such as bad actuator assemblies, frozen motors, controller malfunctions and media damage such as bad sectors and head crashes. Here are are some other types:

  • Corrupted RAID configuration
  • Lightning, flood or fire damage
  • Drive physical abuse
  • RAID hard disk drive (HDD) overheat, failure or crash
  • Intermittent drive failure
  • Media surface contamination
  • Multiple drive failure
  • Power spike
  • Power supply burnout or failure
  • RAID controller failure
  • RAID corruption
  • RAID drive incompatibility
  • RAID array failed
  • Vibration damage
  • Damaged connector
  • Manufacturer defect
  • Power circuit malfunction

Human Error

  • Unintended or accidental deletion of files or records
  • Reformatting of drives/array
  • Reformatting of partitions
  • Incorrect replacement of media components
  • Mistakenly overwritten database files
  • Employee sabotage
  • Lost/forgotten password
  • Overwritten files
  • Overwritten RAID config files
  • Overwritten RAID settings
  • RAID incorrect setup
  • RAID user error

RAID Software Issues

  • Backup failures
  • Computer virus or worm
  • Corrupt files/data
  • Damaged files or folders
  • Directory corruption
  • Firmware corruption
  • Repartition
  • Server registry configuration error
  • Missing partitions
  • RAID configuration error
  • Reformatting

Application Failure

  • Applications that are unable to run or load files
  • Corrupted database data or other files
  • Locked databases preventing access
  • Deleted tables
