Data Compass Premium RAID Recovery Utility
As well as the comprehensive data recovery and bad sector handling capabilities of DataCompass, the premium version complements this with the new RAID Recovery Utility. This offers logical analysis, both automatic and manually configurable of multiple disk RAID array systems.
It is designed to facilitate recovery of data where:
Array member disks have failed or are missing
Array configuration or parameters are corrupt or unknown
Software or hardware controller cards have failed
Existing physical member disks or logical disk images, however connected to the system running the utility, can be selected for analysis. The utility supports (uniquely in some cases) the following RAID types, and controller vendors:
RAID 0
RAID 1
RAID 5
RAID 5E
RAID 5EE
HP/Compaq
AMI Linux-standard
Adaptec
Backward/ forward dynamic parity
It works to extract data from the multiple drives that make up a RAID system, and to rebuild this data across the RAID array, independently of any controller card or software.
The essence of the RAID recovery procedure is to crack the algorithm employed by the multiplicity of RAID controller cards and/or software, to directly analyse the data interspersed among multiple member drives and reconstruct it in a correct form to new storage volumes. Once the restored volume is established, the data can be examined and/or recovered using the normal DataCompass file recovery functionality.
The detection of the RAID parameter configuration is the key to recovering the often critical user data from failed RAID systems. The utility will either detect the configuration automatically, or guide the user to manually detect it by selecting the appropriate configuration options until the array is successfully rebuilt. These configuration parameters include:
Array member disk order (including missing disks)
Stripe size
Stripe start point/header offset
Parity type
Parity direction
Parity delay
This RAID utility adds to already highly successful Datacompass capabilities to form a comprehensive data recovery solution.
