How to Handle RAID Level 5 Array Failure
RAID 5 is a popular RAID (Redundant Array of Independent Disks) level, which uses distributed parity and block level striping. This RAID level attempts to remove bottleneck of dedicated parity drive. Using distributed parity algorithm, RAID 5 writes parity data across all drives. Generally the blocks are used for creating parity blocks that are then stored across array. It removes bottleneck of writing to just one parity drive. In spite of high stripping, the RAID 5 array may also fail and you might come across critical data loss situations. At this point, you are required to go for Data Recovery Services to get your mission critical and precious data back.
In RAID 5, the parity disk rotates based on parity rotation algorithms for that specific RAID software or card. One difficulty could be expected in some situations and that is presence of an offset. The offset is a number of disk sectors before first stripped block. Presence of an offset is familiar in Adaptec cards. The offset may easily be found by searching for partition table. The RAID 5 array may fail and data loss may occur due to any of the following reasons:
RAID controller malfunction
Volume reconstruction issue or RAID rebuild error
Missing or lost RAID partition
Multiple RAID disk failure in off-like mode, causing loss of disk volume
Power surges
Disk formatting or accidental deletion
Virus infection
Missing configuration settings and system registry
Wrong replacement of disk element belonging to working RAID volume
Missing RAID parity
When any of the above situations occur, your RAID 5 array might fail and all of your mission critical data becomes inaccessible. In such situations, it becomes extremely important to sort out the issue and carry out Data Recovery NJ to gain access of your valuable data.
