Recover Data from RAID 5 Disks

What is RAID on Windows?

RAID stands for (Redundant Array of Independent Disks). It is a data storage technology which employs a technique of combining multiple Hard Disk or SATA Drives into a logical disk in order to improve performance and data redundancy.  There are different RAID levels like RAID 0, RAID 1, RAID 3, RAID  4 RAID 5, RAID 6, RAID 10, etc.

Here, let’s try and understand the basic logic and purpose behind a RAID 5 disk and after that let’s learn what the reasons causing data corruption / loss on RAID 5 Disks are and as well as how to perform RAID 5 Disks data restoration on Windows.

What is a RAID 5 disk?

A RAID 5 Disk is one of the most common configurations of RAID used for business servers and enterprises as RAID 5 provides comparatively better overall performance and error tolerance than other RAID configurations. A RAID 5 configuration consists of striped blocks with distributed parity spread over three or more disks. The parity is used as additional data for recovery purposes. Benefits of using RAID 5 Disks are, if one of the disks has encountered an error, the overall disk still continues to work until the damaged disk is replaced. Another advantage of RAID 5 Disk is that if there’s damage in one of the disks, the damaged disk can be easily swapped with a healthy disk without having to interrupt the access to other users of RAID 5 Disks.

Top reasons leading to a RAID 5 disk failure:

A RAID 5 Disk configuration is very good when it comes to fault tolerance but over usage and improper functioning of the disk causes the RAID 5 Disk to fail. Some of the most common disk failure scenarios are mentioned here.

  • When one of RAID 5 Hard Disks fails, there is no sudden replacement to that failed Disk as there is not standby readily available. As a result, at this time, the RAID Disk is running on degraded condition. Hence the working of RAID array in this condition causes further damage to the RAID 5 Disk
  • Most of the RAID Disks functions with a single controller and any failure related to the controller causes large single point failure of the arrays
  • Due to frequent power surges and sudden outages, the RAID 5 Disks could get damaged resulting in data loss
  • Reconfiguring the RAID 5 Disks due to any reason or while replacing the failed Disk improperly, leads to data loss on those Disks
  • Any RAID 5 configuration provides resistance from physical failures only. Damages due to viruses and malwares and other system related corruptions are not resisted by this configuration
  • Unintentional or accidental data deletion is always a reason leading to recover data from RAID 5 Disks
