The Truth about Recovering RAID 5 with 2 Failed Disks

RAID 5 is widespread enough. It has an advantage in an independent stream of data from several disks in the array, which can be processed in parallel. The parity data is distributed across all the disks in the array.

However, there may be problems with RAID 5 having failed disks. For RAID 5, correct work needs at least 3 drives. What to do, then, if you can’t open a disk from RAID 5? It does sound scary if there is one failed drive, but sometimes, it is even two...

How do you recover data from RAID 5 with 2 failed drives? Read on to learn how to solve this problem.

Why does RAID 5 fail?

In order to understand how to recover data from RAID 5 with 2 failed drives, you need to remember what caused the failure. The following are the main causes of RAID 5 drive collapse:

  • RAID partition absence
  • Using a failed disk; e.g., there was an attempt to get back a RAID 5 array back online
  • One-time multiple drives failure
  • Incorrect RAID volume settings
  • Malware
  • Viral damage
  • Non-working controller

Recovery software for RAID 5

Data recovery software is the main solution for a broken/damaged/failed RAID. Using good quality data recovery software, you can recover your RAID 5 data as much as possible.

One of the great and outstanding software solutions for such situations is RAID Recovery™. RAID Recovery™ by DiskInternals is the most powerful professional tool for this purpose.

It supports Apple, Linux (NAS), Microsoft software RAIDs (also called dynamic disks), including JBOD (span) configurations, RAID 0, 1 and 5, QNAP RAID, and mdadm RAID.

DiskInternals RAID Recovery™ works with Adaptec, HP, Dell, MegaRaid, Silicon RAID controllers and DDF-compatible devices. Virtual disks can be mounted as local disks available in Windows Explorer. DiskInternals software supports both manual management and fully automatic detection of the type of array, type of RAID controller, band size and disk order. In addition, the interface is quite simple and easy to use.

Using RAID data recovery software, you can easily recover data from RAID 5 by yourself.

Possibilities for Recovering Data from RAID 5 with 2 Failed Drives

Two failed drives — not the easiest task to solve. But it is worth a try to recover data from RAID 5 with two failed drives. There are many software tools on the Internet that promise to restore data in this situation. However, this is not quite true. You are misled. In fact, when there are two absolutely failed disks, there is not much choice. The best option is to bring two failed disks from the RAID 5 array into a recovery service. Recovery services can take an image from each disk (at least, they can try to do that).

The moment you have the images, you can try to recover data from RAID 5 with two failed disks by yourself. And the only thing that you now need is RAID data recovery softwae. The recovery process with DiskInternals RAID Recovery™ is not so difficult, as with another software. Due to the recovery wizard and recommendations, you can easily perform the recovery process.

Follow the step-by-step instructions that are described below.

Steps to Recover Data from RAID 5 with 2 Failed Hard Drives.

You can use a free trial version of RAID Recovery™ to evaluate if it is possible to recover RAID.

  1. 1. Connect the array drives to the computer as independent local drives.
  2. 2. Download and run Diskinternals RAID Recovery™ data recovery software.
  3. 3. Next, open and mount the disk image that you get from the service. Click on “Drives” -> “Mount image” -> “RAW disk image” -> “Next” -> “Select and attach disk image”.
  1. 4. After you have attached the disk, click on “Commands” -> “RAID Wizard”.

  1. 6. Select disks and where RAID will be reconstructed. Click the “Next” button.
  2. 7. In the new window, click on “Arranged by RAID levels” and select your RAID array type (RAID 5).
  3. 8. Reconstructed RAID will be added to the list of disks and marked in red.
  4. 9. Now, it’s time to recover RAID data. Right-click on the reconstructed RAID and select “Open as” -> “Reader” or “Uneraser”.
