“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.

Windows’s check disk action: If the disk partition or the files of RAID 6 go unreadable, Windows operating system executes its in-built disk check tool automatically when you reboot your PC. It is especially so when your RAID 6 disk is readable, resulting in data corruption on the RAID disk.
Corruption of Hard Disk in RAID 6: If any of the arrays of RAID 6 has bad sectors on the hard drive, the particular drive will typically stop working once the two hard drives get failure. You can also get some signs of the hard drive being offline.
Failed disk space expand actions:When you wish to extend your disk space without any damage to the previous data, there are high chances of data loss. Due to bad sectors and sudden power-offs, you end up in data loss on the expanding process.
Sudden computer power off:Designed by the combination of hard disks, RAID 6 is a logical array hard drive controlled by a RAID Card. When huge amount of data is stored on RAID Card or the mainframe, sudden power off your computer may not store the information on ROM, resulting in data loss and RAID array failure.

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.

Failed Mount Actions: When you enter or run the mount commands, you cannot mount the file systems.
The disappearance of Partitions: When the array has bad sectors, the file partition and the content gets lost.
Inaccessibility to the operating system: If the RAID array fails, the hard disk becomes inaccessible and unrecognizable that give errors. You can see messages like “Disk Boot Failure Insert System and Press Enter” and “Operating System not found.”

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.

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.

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.

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.
