Specific failures on RAID systems that we can recover data from include:

RAID array / Controller Card Failure
Controller Card Set-up Corruption
RAID Container Crash
Server won't boot
Server registry configuration lost
Rebuild failure
Damaged striping
Multiple hard disk drive failure (or multiple drives go offline)
Intermittent drive failure resulting in configuration corruption
RAID array or volumes that won't mount after a server crash
Configuration damage or corruption
Addition of incompatible drives
Hardware conflicts
Software corruption
Software or operating system upgrades

Data Clinic's Recovery Process for Servers, NAS, or RAID Arrays

Our technicians treat Server and RAID data loss situations as high priority cases. An initial diagnosis determines whether each media device is accessible to our lab equipment. If so, the first priority is to create a raw image of all data from accessible media onto new media so that logical analysis can determine the nature of the information loss situation

If some of the media is inaccessible our lab will test the components and closely examine its internal health to determine the extent of physical damage.

Recovery of crashed RAID and other hard disks often involves replacing failed or damaged components in a clean environment and using specialized hardware and software tools to create the raw image. Failed components typically include electronics, read/write heads, head assemblies, magnets & drive motors.

Logical RAID data recovery uses the raw images of all the server's media by examining the low-level data sectors. Technicians must determine both the exact layout of volumes which span or are striped across multiple drives and what fixes to filesystem structures are needed to get access to the important data.

Multiple-drive servers are typically 'destriped' onto our media so that filesystem repairs can be performed and the data files extracted. Sometimes the existing filesystem structures are missing or damaged so much that data has to be extracted directly from one or more fragments of the destriped image.
Our programmers have created a full set of software tools used by our technicians to analyze, destripe, fix & recover data from raw images drives to virtually all operating systems. Once a recovery has been successfully performed, file lists are created and information validity is checked.

"Data Clinic's achievements in the field of data recovery consistently break new ground and move the industry forward"

Dr P Nutter
Lecturer in Computer Science and Data Storage Technologies
The University of Manchester

"Thank you Data Clinic for the excellent service you provided in restoring all of the data from the RAID drives. Although the solutions that Data Clinic provide are clinical in nature, the people are professional, friendly and bend over backwards to get the job done. Highly recommended."

C Russell, Digital Asset Solutions

"I found Dataclinic to be highly efficient, professional, and gave great customer service. Within 36 hours of a system failure we had our data recovered from the server, restored and installed. This was despite the geographic issue of being some 270 miles between ourselves and DataClinic, and the fact that the server was shipped back on a Friday afternoon. Excellent service."

RAID-0
Level 0 is not redundant, hence does not truly fit the "R.A.I.D." acronym. In level 0, information is split across drives, resulting in higher data throughput. Since no redundant information is stored, performance is very good, but the failure of any disk in the array results in information loss. This level is commonly referred to as striping.

server data recovery

RAID-1
Level 1 provides redundancy by writing all information to two or more drives. The performance of a level 1 array tends to be faster on reads and slower on writes compared to a single drive, but if either drive fails, no information is lost. This is a good entry-level redundant system, since only two drives are required; however, since one drive is used to store a duplicate of the other, the cost per megabyte is high. This level is commonly referred to as mirroring.

RAID-5
Level 5 employs a combination of striping and parity checking. The use of parity checking provides redundancy without the overhead of having to double disk capacity. Simply put, parity checking involves determining whether each given block has an odd or even value. These values are summed across the stripe sets to obtain a parity value. With this parity value, the contents of a failed drive can easily be determined and rebuilt on a spare drive.
