Most businesses use RAID array systems for transferring, storing or keeping data backup because of the redundancy feature RAID system offers, especially RAID 5.

The redundant array of independent disks or, for short, ‘RAID‘ stores data across the array equally, but when one disk fails, the system still works due to the RAID system’s fault tolerance.

Unfortunately, RAID systems are vulnerable to failure regardless of fault tolerance features due to human, electrical or mechanical errors.

The system is complex, and if you try to fix things and during this, something goes wrong, you can tend to lose your data forever. Here are some of the steps you should avoid while your RAID fails to reduce the possible chances of permanent data loss.
