RAID Data Recovery is one of the most complex data recoveries which we at Disk Doctor Labs have successfully performed, within the industry we have been rated as one of the pioneers of RAID Data Recovery and have an experience of thousands of mission critical successful recoveries with us.
Mostly, the causes for failure of the RAID array is mainly due to human error and further we have seen that let me try myself feeling from the customer has actually has aggravated the failure, eventually which resulted in irrecoverable loss of critical data.
RAID may be considered as fault tolerant, however is not data loss proof.
The best way to deal with RAID array failure is Leave it Like that only and call professional Data Recovery Company such as Disk Doctor Labs, Inc. for further evaluation and recovery of mission critical data. The complexity of RAID Recovery depends on the level of RAID. We follow a specialized process for recovering data from RAID arrays.
How Raid Array Analysed
Upon receiving your request for the analysis of the RAID array, we gather valuable information about the RAID array, such as:
• Level of RAID i.e. RAID 0, RAID 1, RAID 0+1, RAID 5, RAID 5+1 etc.
• Exact cause for the failure
• RAID controller information (HVD or LVD card etc., in some cases we might require to ship the RAID controller along with the drives.)
• The series in which the drives were attached in the array
• Complete details of any hit and trial method which has been tried before sending the job to us.
• Details about the failed drives in the array, maintaining there order in array series
• Once we receive complete information as mentioned above we start the recovery process, there are various specialized methods of recovery which may include.
Taking failed drives to clean room and getting them to work
• To create a secure replica of complete array with a specialized in-house technique.
Identifying parity technique, using in-house developed applications
• Then proceeding ahead recovering data following parity order and picking fragmented stripes together (applicable to RAID 5 arrays)
• There is more complexity involved besides the points mentioned above, which is tackled with other in-house developed techniques. Once everything goes well data is recovered to the expectation and is delivered to you on choice of your media.
• To recover data from all the below mentioned cases we follow a standardized data recovery process in all our data recovery labs across the globe.
