RAID 0, 1, 5, 10 Data Recovery

At Mass Data Recovery, we recover data from all kinds of multi-disk setups. We can handle it all, from just a bunch of disks (JBOD) to every RAID configuration: RAID 0 to RAID 10. Whatever your RAID Data Recovery needs are, be sure to contact our RAID and server experts for more information.

 

Successful RAID Data Recovery

To successfully recover data from a RAID setup, all drives are always required. This is true even if the problem was caused by only one failed drive. The data is split evenly between the drives. Therefore, the data recovery cannot succeed with just the one failed drive.

 

You will need a RAID data recovery if any physical damage to the drive(s) has occurred. The RAID needs to be repaired before the structure can be recreated in the lab. Only then, can a full RAID recovery be created on a healthy drive.  If your RAID recovery situation requires a hardware RAID card, we will need the actual RAID card, as well as all hard drives used in the setup. This ensures that the specific RAID setup can be completely recreated and your RAID recovery will succeed.

 

Why RAID Arrays Fail

There are four general categories around failure: RAID Hardware Failure, Human error, RAID Software Failure and Application failure.

RAID Hardware Failure

  • Actuator failure
  • Bad sectors
  • Memory or controller failure/malfunction
  • Corrupted RAID configuration
  • Lightning, flood or fire damage
  • Damaged motor
  • Drive physical abuse
  • RAID hard disk drive (HDD) overheat, failure or crash
  • Head crash
  • Intermittent drive failure
  • Media damage
  • 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
  • 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 configuration files
  • Overwritten RAID settings
  • RAID incorrect setup
  • RAID user error

RAID Software Failure

  • 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

 

Supported File Systems

We support all kinds of file system formats:

  • FAT12
  • FAT16
  • FAT32
  • NTFS
  • Apple Mac OS and its HFS(+) file system.

We also cater to the Linux file systems, ext2, ext3, ext4.

From a single drive to a much larger setup, such as RAID or JBOD, we can handle all of your problematic data situations.

 

It is evident that there are many factors that may contribute to a hard drive failure. We have outlined only the most common occurrences. If your RAID Array is experiencing other symptoms, we are still able to help. We pride ourselves in our ability to recover data from any type of failure. We are not limited by the complexity, brand, size, or manufacturer of your hard drive.

What To Do If Your RAID Array Has Failed
If you suspect that you are in need of RAID Data Recovery, taking certain precautions can dramatically increase the chances of a successful recovery. Continuing to power up a failing hard drive can cause irreversible damage and may result in an unrecoverable hard drive. If your RAID array shows symptoms of failure, discontinue use immediately.
Types of Hard Drive Failures

Over time hard drives are bound to fail. There are two main types of hard drive failures. The most common is a logical failure. The second type of failure is a mechanical or physical failure.

Logical Hard Drive Failure

The hard drive’s internal components are functional, but other complications make the data inaccessible. The integrity of the data is compromised and the stored data is damaged in some way. Common causes of logical hard drive failures include accidental formatting or deletion of files, corrupt or missing partitions, operating system errors, a corrupt file system, or a computer virus.

Mechanical Hard Drive Failure

Hard drives contain internal moving parts. When a mechanical or physical failure occurs, one or more of the internal components has malfunctioned. The drive may be experiencing difficulty spinning or, in some cases, it may not spin at all. This will result in data that cannot be accessed unless the drive is opened.  This requires a clean room environment where the hard drive can be rebuilt mechanically. Common causes of mechanical hard drive failures include head crashes, alignment issues, a broken motor, or spindle problems.

What to expect

The initial evaluation usually takes between 1-3 business days depending on the extent of the damage. Upon completion of the evaluation, you will receive an exact quote for the recovery.  We will also provide you with the estimated time to completion and probable success rate. You can stop by anytime.  An appointment is not required.

What is the price of the recovery based on?
Although many factors determine the cost of data recovery, it is based primarily on the level of damage to the hard drive.  Detailed reconstruction is often required to get the drive back to a point where the data can be read properly. Once the drive has been rebuilt, successfully extracting the data is the easiest part! Whether its one file or a million files, the work required to get a drive operational is the same. As such, the amount of data usually doesn’t affect the price.

Mass Data Recovery uses a Class 100 clean room for hard drive data recovery.
A Class 100 rating means that the company has followed federal standards for air quality control. For more information on our clean room, click here.
