“Very good turnaround and excellent service and excellent staff (Ali and Tony). RAID data recovery is not an easy task. I was constantly kept informed of the process and my files were 100% recovered. I hope this does not happen to our company again but would not hesitate to contact CDR Data Recovery again. I will definitely recommend them if I know of anyone in the same situation. Good Job.

Critical Data Recovery Lab Inc.

Specialist in all available RAID arrays on the Market today including NAS/SAN Servers, RAID 0, RAID 5, RAID 1, and RAID 10 and others. Regardless of the size of the RAID, configuration, operating system or platform of your RAID Array, CDR’s highly qualified data recovery engineers can recover your data even if all other means of retrieval have failed. WE at CDR welcome RAID arrays being unsuccessfully attempted by any other data recovery company. Engineers at CDR takes RAID jobs as a challenge and recover data as much as possible. Critical Data recovery Lab Inc. has Certified RAID data recovery engineers, and we utilized our proprietary software and hardware specially developed for data recovery of different kind of enterprise storage arrays, to get your data back in quick time at reasonable cost.


RAID Failures Causes:

  • RAID Controller failure
  • RAID configuration lost
  • Accidental reconfiguration
    and initialization of RAID array
  • Multiple drives failure
  • RAID partition missing
  • Partition was formatted
  • Virus Damage

Raid data recovery Process

CDR engineers treat every RAID recovery as a priority job. Once the the server or drives reached our lab, engineers will evaluate them and find out exactly the problem with the RAID server. In the evaluation, Engineers will determine whether RAID has logical corruptions to the file structure, or drives in RAID have physical damage. If logical Corruption engineer will make a raw image to CDR media and destripe them using proprietary tools (software and hardware) this process can be repeated several times to get better result. In case of physical damage to the drives, each drive will be fixed, and then raw image will be taken , and destripe process will be done on the whole RAID.


Data Recovery Prices

Critical Data Recovery Lab have recovered from Several RAID, NAS Servers over the years. As no two data recovery situation are identical , Therefore, it is impossible to give a fix pricing without the initial FREE Evaluation. Generally speaking, Standard price Range is From $1000 to 5500. Emergency service is available 24/7.


Raid Disk Data Recovery Turn Around Time

Critical Data Recovery Put all its resources to recover your valuable data as fast as possible. As every situation is differed in RAID data recovery Time can not be fixed until the server is evaluated. The free evaluation is started as soon as we get the media, and evaluation RAID server will be done within 2 to 6 hours, depending upon condition of the drives in RAID server. Complete RAID data recovery turn-around time including free evaluation is usually between 3 and 7 days. Some severe cases can take more time.

We also provide Rush Service on RAID data recoveries. Which means CDR RAID recovery engineers will work 24/7 on the JOB and try to finished it as soon as possible. which may be 1 to 2 days.

RAID Level 0

RAID 0: Also known as “Disk Striping”, this is technically not a RAID level since it provides no fault tolerance. Data is written in blocks across multiple drives, so one drive can be writing or reading a block while the next is seeking the next block.

RAID Level 1

Known as “Disk Mirroring” provides redundancy by writing twice – once to each drive. If one drive fails, the other contains an exact duplicate of the data and the RAID can switch to using the mirror drive with no lapse in user accessibility. The disadvantages of mirroring are no improvement in data access speed, and higher cost, since twice the number of drives is required. However, it provides the best protection of data since the array management software will simply direct all application requests to the surviving disk members when a member of disk fails.

RAID Level 3

RAID level 3 stripes data across multiple drives, with an additional drive dedicated to parity, for error correction/recovery.

RAID Level 5

RAID level 5 is the most popular configuration, providing striping as well as parity for error recovery. In RAID 5, the parity block is distributed among the drives of array, giving a more balanced access load across the drives. The parity information is used to recovery data if one drive fails, and is the reason this method is the most popular. The disadvantage is a relatively slow write cycle (2 reads and 2 writes are required for each block written). The array capacity is N-1, with a minimum of 3 drives required.

RAID 1+0

This is stripping and mirroring combined, without parity. The advantages are fast data access (like RAID 0), and single ¡V drive fault tolerance (like RAID 1). RAID 0+1 still requires twice the number of disks (like RAID 1).

Raid Level 10

Also known as block mirrored, it required minimum 4 disks. It has fast accessibility the blocks are mirrored and striped. The RAID level 10 is the recommended option for small and large business for their critical information.
