RAID Recovery

Expert RAID recovery services in the North West of England

RAID Array Data Recovery Services.

For further information on Server and RAID array data recovery please visit our dedicated website.

Hard disk drive and solid state disk RAID arrays are frequently used to store vital information. When they fail it can be a stressful for situation even for the most experienced IT professional. Reconstructing a failed RAID array requires expert knowledge of both system controllers and filesystems. CDR – Manchester Data Recovery Services – offers data recovery for all server and RAID configurations, including:

  • RAID0 – Striped disks
  • RAID1 – Mirrored disks
  • RAID5 – Striped disks with parity
  • RAID6 – Striped disks with dual parity
  • RAID10 – Stripe and Mirror

CDR offer free consultation, free diagnosis, and free turnaround time estimate. CDR offers data recovery services to a timescale that you require. It is also possible for CDR to send out a technician to your building to examine the RAID array. Moreover, ahead of any payment CDR will send you a file listing detailing the recovery, it is only once you have approved this file listing that payment is requested. This way we ensure that recovery is successful on your terms.

About RAID

“RAID” is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. The different schemes/architectures are named by the word RAID followed by a number, as in RAID 0, RAID 1, etc. The various designs involve two key design goals: increase data reliability or increase input/output performance. When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes including increased performance and redundancy with the ability to allow large multi-terabyte storage volumes.

Why does RAID fail? Systems can fail due to the following reasons:

  • Mechanical or physical failure of hard disk drive
  • Firmware failure
  • Controller / motherboard failure
  • Power failures or power cycling
  • Multiple hard disk failure due to electrical surge
  • Failure of multiple SSDs
  • Multiple disk with unreadable sectors / bad blocks
  • Corruption of the filesystem
  • Physical shock
  • Fire / flood damage

Do not leave the recovery of your critical data to chance. Initialising a rebuild can cause unrecoverable data loss. If you require data recovery from your device then please turn the device off and contact CDR for expert help. CDR has a very high success rate in the recovery of data.  Please see these example of CDR’s previous work on RAID and server recovery. CDR has the capability to recovery data from proprietary configurations, including those used by Apple Xserve, Adaptec and HP.

All data recovery work undertaken by CDR is on a free diagnosis and a “No-recovery, “No-fee” policy.
Synology RAID

Synology RAID array with 8 disk WD Red setup

RAID 0

RAID 0

RAID 0 (or ‘striped’) data distribution, as pictured. Data is spread over two physical hard disk drives.

It provides improved performance and additional storage but no redundancy or fault tolerance.

A single disk failure destroys the entire array because when data is written to a striped drive set, the data is broken into fragments.

This setup is commonly found in Lacie Big Disk and G-Tech drives.
