RAID 5 is a robust storage solution among all the RAID levels. It contains a minimum of three drives and offers robust performance and data redundancy. The parity data is striped across all the disk drives. It means RAID 5 can withstand one drive failure. But, what happens if two or more drives are failed in the RAID 5 array? How would you recover your data then?

There are ways to restore data from RAID 5 with 2 failed drives. In this blog, we’ve mentioned the methods to recover data from RAID 5 when two or more drives are failed. But before moving on to the methods, let’s learn the causes that may lead to drives’ failure in a RAID array.

What Causes Disk Failure in RAID 5?

Several factors may cause drive failure in RAID 5. Some common ones are:

  • RAID partitions are not configured
  • RAID controller malfunction
  • Re-establishing RAID 5 array with a failed drive
  • Unexpected power breakdown
  • Malware attack
Important Note: RAID controller may not remain active after the failure of two drives. Therefore, immediately stop performing further actions.

How to Recover RAID 5 with 2 Failed Drives?

Here are some safe and effective methods to recover data from RAID 5 with 2 failed drives:

Method 1: Recover Data from RAID using Backup

RAID is never a backup solution. Similar to other storage drives, it may fail due to several reasons. Hence, it is always recommended to take a backup of your RAID array. And, if you have the RAID 5 data backup, you can easily get it back by following the given steps:

  1. First of all, verify if the available backup drive is completely functional and free from any error.
  2. Connect the backup drive to your system and store it in a different location.
  3. Replace the failed drives in the RAID 5 array.
  4. Connect the RAID 5 to the system and upload the backup drive data on the freshly configured RAID 5.
  5. Next, check if the data is available on RAID 5.

Limitations:

  • Recovering data from a backup drive is time-consuming.
  • Chances of data loss if the backup drive is not fully updated.

Method 2: Use a Powerful RAID Recovery Software

The best way to recover RAID 5 with 2 failed drives is using powerful data recovery software, such as Stellar Data Recovery Technician. It is an easy-to-use, DIY software that can efficiently retrieve the lost or deleted data from RAID drives. Additionally, it can restore data from corrupt, broken, or failed RAID arrays, including RAID 0, RAID 5, and RAID 6. It can also restore data from formatted RAID logical volumes.

Steps to recover data from RAID 5 by using the software:

    1. ‘Download, install and launch Stellar Data Recovery Technician

    1. Select the What to Recover screen, select ‘Everything’ or choose the type of data you want to restore.
    2. Next, on the ‘Recover From’ screen, select ‘RAID Recovery’.
    3. Select the RAID 5 and its available parameters.
    4. Scan and retrieve data in the accessible form.
    5. Finally, click Save to store the recovered data at the selected location.
    6. After recovering data, you can proceed to rebuild the RAID array by clicking Build RAID.
