“Is it possible to performRAID 6 Data Recovery after a disk failure?”

When it comes to information technology and its concepts, there is always a demand for reliable data storage that is secure and fault-tolerant. In such cases, RAID becomes the preferred choice by most computer users for its high data storage ability. Particularly, RAID 6 gets its place on the top as it stores bigger data capacity, has chipper desktop-class hard drives, and protects the data from getting lost even if any disk or array failure occurs. But, unfortunately, RAID 6 cannot resist the failure of two drives simultaneously, resulting in data loss or intact functionality if more failures occur. Then, is it possible to recover RAID 6 data, and, if yes, how to perform it? Scroll through to find out an answer regarding all your RAID 6 Data Recovery relates questions.


Part 1: Overview on the RAID 6 Data Recovery

What is RAID 6?

With reference or similarity of RAID 5, RAID 6 was developed with a more extensive data storage capacity by implementing four hard disk drives. Integrated with the dual parity technique, RAID 6 array stripes data with the two independent distributed parity schemes, enhancing better data redundancy.

Compared to RAID 5, the performance is higher in RAID 6 due to the Reed-Solomon Code Algorithm based on Galois Field Algebra. Due to this, you can perform a faster reading, speeder writing action depending on the data, improved fault tolerance, degraded mode operation, and cost-effectiveness. Being used in ATA and SATA disks for business data, you can say that RAID 6 is reliable as you can still recover data even if the two arrays or disk goes failure. But, if it increases, there is a strict need for a RAID 6 Data Recovery action. 

Causes ofRAID 6 Disk Failure

Here are a few reasons due to which your RAID 6 disk may run failure or go intact.

Symptoms of RAID 6 disk failure

Some sure signs or symptoms would reveal to you that the disks of RAID 6 are infected or the array hard disk has encountered failures.


Part 2: Solutions to fix the RAID 6 Data loss

Once you have noticed that the RAID 6 array is in lousy condition, execute the below-suggested RAID 6 Data Recovery solutions.

Solution 1: Replace or repair the RAID Array

If only a single drive fails, you can repair or replace it with the new array. However, making a backup of files is essential before the replacing action.

Solution 2: Use of Data Recovery Services

Suppose you have encountered RAID array failure that has resulted in data loss. In that case, you can try out data recovery services offered by experts or engineers with relevant knowledge on RAID Data Recovery. Gillware, and DriveSavers are some examples of data recovery services.

Solution 3: Use of Data Recovery Software

If you failed the RAID 6 array and wish to recover the data from the inaccessible RAID controller, you can use some data recovery software platforms like Stellar. Capable of operating on different RAID levels like RAID 0, RAID 5, and RAID 6, Stellar Data Recovery is easy to use.

Tips to Recover RAID 6 Data

While you are now aware of the solutions to execute recovery of RAID 6 data, here are a few tips or tricks.

  1. An up-to-date data backup is an excellent idea

While data loss is a severe issue, you should always be ready for such system failure or RAID array failure event. Yes, have a backup of all the data the seems vital from your point of view. Instead of physical, have a cloud-based backup as if the RAID failure is severe, your data will disappear.

  1. Check the hardware status routinely

To be prepared for instant hardware failure, check the status of the hard drives at periodic time intervals. If you suspect or if you encounter any of the symptoms listed above, never hesitate to look into it at the instant. If a hard drive fails, replace it immediately or execute a data recovery plan.

  1. Don’t attempt any DIY rebuild or data recovery

If you have no idea why has the hard disk of RAID 6 has failed or the cause of the hardware failure, never attempt a DIY rebuild or manual data recovery methods.     


Bonus Tip – How to recover data from hard drive?

While the above sessions are related to the RAID 6 data recovery, solutions, and tips, here is a special bonus tip that helps you to recover the corrupted data, deleted or lost data from the general hard disk and or disk partitions. It is none other than Recoverit from Wondershare.   

Wondershare Recoverit is a cost-effective data recovery software from Wondershare used to recover lost, corrupted data, restore files from the emptied recycling bin, repair corrupted videos, and retrieve data from crashed computer. Recoverit can recover data at a higher rate, trusted by millions of users and top global leaders. With support to all types of data like NTFS, APFS, FAT, and a lot more, Recoverit is 100% safe.

How to perform data recovery from general hard drive with Recoverit?

To recover deleted or lost data from general hard drive with Recoverit is accessible with the below manual based on your system requirements (Mac or Windows).

Step 1: Launch Recoverit

Once downloaded and installed, launch the Recoverit application on your desktop.

Step 2: Selection of the location

Now, select the place from where you want to recover data. You can choose a hard drive, external devices, or desktop as per your requirement.

Step 3: Scan the disk

Once the location is specified, Recoverit will start an all-round scan and display the data found on the disk or site.

You now preview the files and hit the “Recover” option to retrieve the files to your system.


The Bottom Line

As the next top step on the Data Warehouse Technologies, RAID 6 is the best physical drive for your computer for a reliable data storage solution. If you have recently noticed any disk or array failure on your RAID device, execute the above-discussed techniques. If you are worried about data loss, go for a data recovery action with Recoverit from Wondershare! Finally, with the practical implementation on how to perform RAID 6 Data Recovery, we have reached the end of our today’s article!


People Also Ask

  1. What are the factors responsible for data loss in RAID 6 arrays?

RAID 6 array can withstand data loss even if two disks or array gets affected, but sometimes hard drive failures result in data loss. To be specific, Intensive rebuild or electrical events, logical failures, accidental file deletion, software errors, and virus damage are the critical factors responsible for data loss in a RAID 6 array.

  1. In RAID 6, how many drives you need?

To implement RAID 6, you need a minimum of 4 drives and a maximum of 32 drives. Whatever the drive count is, the usable drive capacity to ensure data integrity is two arrays.

  1. Are there any complications during RAID 6 Data Recovery?

Yes, RAID 6 Data Recovery isn’t easy as it uses dual parity. To carry outRAID 6 Data Recovery, you will need a specialized tool and advanced knowledge regarding the RAID Data Architecture.

  1. Is it possible to recover data from RAID 6 with three or more disks failure?

Unfortunately, the answer is no. If it is just a dual-disk failure, data restoration or recovery is possible, whereas, in three or more disk failures, you need to restore the data from previous backup files only.
