RAID Data Recovery Services

RAID or Server Crash? We Can Help.

We can help you recover from single or multiple drive failures in RAID 5, RAID 6, RAID 0, 10, and volume corruption on NTFS, ZFS, Ext3, and Ext4 File Systems.

CDR has been working with businesses and MSPs throughout North America for over a decade.

Here's a quick look at the process in recovering a RAID array

  1. First, we create images of all drives from your array using industry standard tools (PC3000 or DS). These tools will help us recovery data from damaged disks (bad blocks; weak magnetic heads; FW issues, etc.)
  2. Once the drive is completely imaged, we can mount the image of the cloned drives on our recovery server.
  3. Using HEX editing software we can search through hex-data on each drive, attempting to discover what the RAID parameters were.

During the recovery process we need to determine:

  • Order of the drives
  • Size of data-block and size of the parity-block
  • Type of parity order (backward; forward; synch; usynch)
  • Offset (where does the RAID data start on each drive)
  • Which drive we need to skip

After that we can reconstruct your failed array virtually and mount your data partition:

At this point we can now save files and folders to a destination drive, and provide you with a detailed listing of the recovered data.


What makes CDR Core Data Different?

As software developers, we have an in-depth understanding of the firmware operations of today's physical and solid state hard drives. Salvaging data from damaged hard disks is a process which involves firmware re-programming along with replacement parts.

Data recovery services for all types of RAID and models of hard drives.

  • We offer proven strategies and techniques for physically damaged or clicking hard drives, deleted files or formatted computers
  • Personable and "high-contact" service. We guarantee the highest level of customer service.
  • 92% Recovery Success Rate
  • Competitive transparent pricing – ‘No Data, No Charge’
  • Fastest possible turnaround times for all recovery types.

CDR's Data Recovery engineers classify hard drive data loss in two categories:

  • Logical failure - the hard drive is physically working but due to some damage at the file system level or corruption of the actual files the data cannot be accessed. Logical failures include partition corruption, re-formatting and deleted files.
  • Mechanical failure - Physical damage to the hard drive, often caused by head crashes, spindle motor seizure, electrical PCB damage
