RAID data recovery is the specialist practice of rescuing company critical files and folders from an array of RAID hard disks where the controller can no longer access the data. Underlying reasons tend to centre around failure outside operating parameters – such as multiple hard disk failure beyond the RAID level limit. For RAID 5, a failure of two drives simultaneously will cause an array to fail, and for RAID 6, three drives failing will cause the array to fail. When an array has failed, the controller has no way to access the data – swapping out the crashed disks does not help – there are insufficient remaining data and parity blocks to allow automatic reconstruction of the data. The recovery specialists focus on creating a virtual RAID array – starting with the building blocks of data from the operational hard drives, and augmenting with the parts of the failed hard disks which can be accessed through a mixture of proprietary and first principle extraction techniques. RAID data recovery tends to be the preserve of businesses as they own most of the RAID systems in operation, but RAIDs are becoming more popular in the home, albeit misunderstood. Quite often, computers configured online and bought for home use will have a RAID controller for two or more hard drives. Home users will understand that redundancy is important and that two disks are surely safer than one, so they pay the premium. What they do not realise is that they may end up with RAID 0 – where all the data is split between the hard drives, with no parity. This absence of redundancy is almost an oxymoron – and while performance can be breathtaking, the chances of failure are much higher than for RAID 1 which involves mirroring. The trade-off is that RAID 1 provides half the data space of RAID 0 for a typical two drive set up. The big advantage of RAID 1 over RAID 0 is therefore that data recovery services are far less likely to be needed.
