Raid 6 Data Recovery

Computers and Technology

RAID 6 Array is created in point of view for better data protection. It is made with the help of four hard disk drives array and we can implement up-to 16 disks (however usable capacity is only 2 disks instead of all) which stripes or we can say holds data with two independent distributed parity schemes. It is known for its better data redundancy and it is able to handle two data drives failure through better controlling the fault. The write method of RAID 6 is slower with comparison to RAID 5 because it contains two parity blocks while RAID 5 only one.  

It uses XOR logic, better known as “exclusive or” logic which performs parity calculations and works on bit scale. With the help of XOR function, all the bits of one missing hard drive’s data can be reconstructed. XOR logic cannot be filled in the rest of the gaps thus it works only with the one drive missed. In this case, with the five drives, two out of every five blocks contain parity data and the extra parity blocks don’t based on XOR coding. They use Reed-Solomon error correction codes which depends up on Galois field algebra and developed by Irving S. Reed and Gustav Solomon in 1960. It performs robust calculations through which recreation its data based on the parity data with parity blocks of the remaining drives.    

RAID 6 Hard Drive is less desirable with compared to RAID 5 because of heavy calculations, it takes time to write data and requires more hard drives to have the same amount of space. It is comparatively slower but still in demand due to RAID 5 handles two data drives failure by better controlling the fault.

There are certain reasons for failure of the RAID 6 Drive  –

  1. Virus Damage which is very normal we all friendly with.
  2. Sometimes accidental damage with Fire, Smoke or Water Damage or accidentally deletion of data due to formatting, partitioning or overwriting which is very normal process.
  3. Re-initialization caused overwrite.
  4. Damaged RAID Controller Card can also be an issue.
  5. Error in perform logical operations.
  6. Electric fluctuation.
  7. Insufficient disk space or expending disk space improperly.
  8. Check disk tool failure.

There may be several other technical reasons which are enough to RAID 6 failure but, with the help of advanced technology and specialized companies like salvagedata.com, everything can be recovered.
