RAID Data Recovery

We can help you recover data failed RAID-0 and RAID-5 arrays:
JBOD (Spanned ) volumes – LaCie & Western Digital NAS Drives often use this setup.
RAID 0 (Disk Striping) – LaCie, Western Digital and other high speed hard disks use this setup.
RAID 1 (Disk Mirroring) – Western Digital & Maxtor external hard disk often use this setup.
RAID 5 (Disk Striping with Parity) – Dell, HP, Compaq, IBM Servers and onboard motherboard RAID controllers use this setup for data protection.
All other RAID levels including RAID-6 – Windows, Mac, XFS and Linux
The most common problems we see is when 2 hard disk fail in a RAID 5 array, 1 hard disk fails in a RAID-0 array or a Network Attached Storage External hard drive’s RAID controller/enclosure has failed. Most problems are caused by hard disk wear & tear, a firmware corruption, shock/impact to the hard drives or overheating. Most servers or RAID systems are on 24 hours a day and never powered down. Frequently, RAID-5 systems suddenly report 2 disks as ‘dead’ since 1 disk normally dies at an earlier time without being noticed, the system keeps working and a problem is not discovered until a 2nd disk fails rendering the system Offline. Don’t worry, the chances are we can still recover your data!

RAID Systems
The most common RAID systems we rebuild are from HP, Compaq, IBM, Dell, Adaptec, LaCie, Apple, D-Link and Other NAS Units. Windows, Mac & Linux file systems are our specialty. We can also recover form Vmware and Virtual Machine Environments.

Do not attempt to repair or rebuild your RAID array. If done incorrectly or with the wrong stripe block size or disk order, this may corrupt your data permanently. Shut Down your RAID System, leave all of the hard drives powered off. The sooner you do this, the better your chance of data recovery.
One of our Technicians will carefully remove each disk from your RAID array and note the number the Disk Bay number they are removed from or label them with the SCSI ID or Disk ID if this is known. Once we assess the array at our data recovery centre, we will give you an idea of how long it will take to recover the data and the cost involved. We also offer an emergency service if it’s urgent.

Typical Problems:
RAID controller failure
Rebuild failure
RAID array or volumes that won’t mount after a server crash
Multiple drive failure (or multiple drives go offline)
Partition Corruption or Damage
Lost RAID configuration
Damaged striping
Faulty hard disks in RAID Array.
Configuration damage or corruption
Addition of incompatible drives
Drive not detecting in BIOS
Hardware conflicts
Media surface contamination and damage
Software corruption
Windows Blue-Screen Errors, Cannot access files.
Viruses or malicious intent
Software or operating system upgrade
Un-bootable Systems
Corrupted RAID
Missing Partitions
Controller Failure
Computer virus and worm damage
Natural Disaster
Human Error
Unable to start server
Unable to boot into the operating system
Failed hard disk(s)
Broken raid set
Deleted/broken configuration

Price Guide
The time needed to recover data from a RAID array can vary depending on the brand & model of the RAID Controller, RAID configuration, file system type, the problem with the hard disks, ability to locate spare parts and the condition of the data in RAID array we receive the disks in.
The cost to have data recovered from a RAID array range from $1,200 to $10,000 depending on the complexity of the RAID and the level of urgency.
