RAID
RAID cannot simplify disaster recovery. When running a single disk, the disk can be used by most operating systems as they come with a common device driver. However, most RAID controllers need special drivers. Recovery tools that work with single disks on generic controllers will require special drivers to access data on RAID arrays. If these recovery tools are poorly coded and do not allow providing for additional drivers, then a RAID array will probably be inaccessible to that recovery tool.
