RAID server is not supposed to fail but nevertheless still fails. The reason is simple. It is unlikely that two disks will fail together and that is the perfectly legitimate "pretext" for most not to perform backup.

However, one does not realize when one disk fail, it is very likely that other disks may be failing soon as the same batch of disk arrays have been subjected to the same operating environment and conditions.

As a result, one always gets caught in such RAID array failure losing huge amount of data so critical to business operation, exactly for the same reason why RAID array has been utilized - to protect the valuable data.

In such catastrophe, one could only turn to specialist to recover the unrecoverable. Our engineers have vast experience to handle all of the current RAID server configuration (such as RAID 5, RAID 0 or RAID 1) as well as any legacy systems in the market today.

Types of RAID server we handle

These include RAID servers from IBM, Compaq, Dell, Hewlett-Packard. Hitachi, Sun, NEC. We could also handled Network Attached Storage (NAS) based RAID such as those from Quantum, Iomega, Maxtor, HP or any OEM brand.

Common causes of RAID failures are :

• RAID Controller failure or malfunctioning
• Multiple drive failures one after the other
• Accidental wrong replacement of element components
• Accidental reformatting of drives or array
• RAID goes down after rebuild
• Corrupted RAID volumes
• Virus Attack
• Fire or water damage
• Lost of RAID configuration due to human error

Normally we only need the members of the array to recover lost data. The disk image of each disk member is sector-to-sector cloned as file and individual disk files are then analyzed in a series of de-striping processes. As modern arrays are approaching many terabytes, to expedite the work, we may advise the user to send in the complete RAID array so we could achieve a much higher speed of recovery by extracting the data directly off the original RAID volume on-the-fly using our proprietary software tools.

All RAID disk arrays are treated with high priority as we understand the urgent needs when organizations lose such data. Our recovery process does not compromise the integrity of the RAID array as we always perform read functions only. If any write operation is to be done, it will always be performed on clone images or files.
