A Raid or redundant array of independent disks can provide external storage by combining hard drives in a single array. Raid comes with multiple configurations like Raid 0, raid 1, raid 5 and more. Author Divya Dhami View all posts

Among other configurations, raid 5 is the most prefered configuration because of redundancy or fault tolerance it provides to tolerate failure in one hard disk without harming the entire array.
Although, the raid system can be destroyed if more than one hard disk suffers a failure. To prevent failure in the raid system, some people perform raid rebuild.
To perform a rebuild in the failed raid, you need to be prepared with five things discussed in this article. Following these tips will help you perform raid rebuild successfully.

Bring a compatible hard drive: First of all, you will need to find a hard drive that is compatible with the system. Get a hard drive with the same model and condition as the failed hard drive to avoid trouble while configuring it to the system.

Check backup: As the process requires expertise, you can experience failure during raid rebuild, which can destroy the raid. So you must have an up-to-date backup of all the files to restore them when the raid system fails.

Verify and test the spare hard drive: When you have finally found a compatible hard drive to replace the failed hard drive, it is time to verify it. You will need to check the reliability of the disk if it is good enough and ready to use in the rebuild.

Check raid controller: Once you verify everything to run the raid array normally, we will be required to check things from both ways. Whether its the spare hard disk or the raid controller, examine the working of all the things before rebuilding the raid. Here, the raid controller must be examined if it’s not malfunctioning, or you can suffer a failed raid rebuild.

Turn off the raid system: Be sure of the system if it is turned off. You will have to be attentive during the raid rebuild process. One mistake can destroy the entire raid array and eventually cause data loss. Running the system while raid rebuild can harm the raid array leading to data corruption. So, ensure the system is turned off.


Raid rebuild is not as easy as it may seem. One must have specialized tools and skills to work it out. It takes years of experience and knowledge to rebuild a raid successfully. If you are not an expert, do not ever try raid rebuild. It is a complicated and technical process that professionals can only achieve. Resort to experts with specialized tools and expertise for a successful raid rebuild to prevent data loss catastrophes in your raid.
