Datlabs Capability.
More than ever before, data is a key asset for many organisations, and the security and accessibility of that data is crucial for business continuity.
If your organisation has been disrupted by a loss of data, our RAID recovery experts are on standby to help you get back up and running as quickly as possible.
We provide data recovery solutions for all RAID levels, and we are experienced at dealing with everything from malfunctioned controllers to power surges and virus attacks.
We work with both software and hardware RAID implementations, and our technicians have extensive experience working with all major RAID controller manufacturers, including HP, Dell and IBM.
Our phone lines are manned 24/7, and we offer emergency on-site support throughout the UK.
The RAID Recovery Process.
Here at Datlabs, our specialist RAID recovery technicians have the expertise needed to recover data stored on failed or inaccessible RAID systems.
There are 3 main stages within the recovery process:
- Repair and restore individual failed hard disks to make them operational.
- Rebuild and reconfigure system and file structures.
- Extract and restore your operational data.
We work with all RAID configurations, all hardware manufacturers and all operating systems to minimise the impact of any RAID failure on your business.
Common Causes of RAID Failure.
Common Causes of RAID failure include:
• Controller malfunction.
• Errors rebuilding a volume.
• Missing partitions.
• Multiple offline disk failure.
• Power surges.
• Deleted data.
• Accidental reformat.
• Unintentional reconfiguration.
• Virus attacks.
• Loss of configuration settings.
• Loss of system registry.
• Loss of disk access after system or application upgrade.
Implementations of RAID controllers include Mylex, Adaptec, Compaq, HP and IBM. These implementations can rebuild a failed data volume from a hot standby drive or a replacement drive through a hot swap.
A rebuild will however fail if two disk volumes fail simultaneously or if part of the native configuration is actually stored on a single failed volume. RAIDs can also fail as a result of the following situations and frequently a combination of one or more of them:

RAID Features:
System availability, contingency, security and data protection are the main reasons a RAID configuration is installed. The main feature of a RAID configuration is its redundant hard disk drive storage capacity. Having a RAID data recovery system in place helps ensure that your data is secure with high uptime.
This feature allows the system to reconfigure and remain in service under disk storage failure conditions. High availability in RAID systems comes from the RAID controller's ability to switch to a redundant copy of data in the event
of a single hard disk drive failure. The failure is not transparent to the users since performance is usually degraded whilst the reconfiguration process is in progress, which may take many minutes and in some cases a number of hours.
RAID systems achieve high capacity simply by using a multiple number of hard disk drives. With most RAID systems, the storage efficiency (the ratio of the RAID system capacity to the total capacity of all individual disks) is less than 100%. This is because most RAID systems keep redundant copies of the data and this data must be stored somewhere. Storage efficiency of a RAID system with redundancy is usually 50% or higher.
All RAID systems use the capabilities of multiple disks to improve performance. Performance is enhanced in different ways depending on the configuration. For example, since RAID 1 systems keep an exact redundant copy of data on another disk, they can read a file much faster since they read different parts of the file from each disk. RAID 0 arrays improve read and write performance by splitting files into pieces and storing the separate pieces on multiple disks.
It is important to note that not all RAID systems have all of these attributes. For example, RAID 0 does not provide any increased security or availability when compared to a single disk. RAID 0 systems are built for performance and capacity
only.
For many years, RAID systems were used almost exclusively in high-end corporate data systems where cost of the system was not a concern. In recent years, the number of RAID users has grown dramatically. You may own a RAID system and use it
every day without even knowing it. For example, many high capacity external drives are nothing more than self-contained RAID 0 systems.
Here at Datlabs our RAID Techicians specialise in the recovery of data stored on failed or inaccessible RAID systems. This recovery work involves rebuilding and restoring individual failed hard disks to a working condition, reconfiguring the data structures, extracting and repairing the data from the operational system.
