Data recovery from RAID

Complex data storages or RAID (Redundant Array of Independent Disks) are widely applied nowadays by both corporate and home users as an efficient and inexpensive data storage solution. RAID-systems expand storage capacity, provide for a faster access to information stored on them and increase storage reliability through redundancy - duplication of critical components of a system. Though also called redundant RAID0 and JBOD systems are rather an exclusion as their operation is based on non-redundant algorithm. Despite increased data safety cases of loss of important information from RAID systems occur quite often. Hardware or software failures, power cuts, computer viruses or simply human errors as well as controller or RAID components failures and controller settings reset may be a good reason why the data have disappeared. Yet, following recommendations and considering data storage specifics of a RAID-system you have strong chances to get lost data back.

The data are distributed on a RAID-system across storage components in a way depending on a given RAID type. Thus, when recovering data from a RAID-system you should take into account RAID data distribution algorithm, information distribution algorithm and redundancy. For most RAID-systems preliminary RAID components assembly is required to get access to data on the file system. or reconstruction of a RAID-system and recovery of lost information from it SysDev Laboratories advise to apply UFS Explorer RAID Recovery. This software was specially designed for RAID data access and RAID data recovery. Supporting most RAID types and most data distribution algorithms the software allows for virtual reconstruction of disassembled software or hardware RAID for further access to and, if required, recovery of data stored on it.
