How to recover data from the RAID created using Fujitsu controller

Fujitsu is one of the world's largest players in the development of technologies that solve many modern problems in various fields. For the purposes of this article, we will focus on RAID controllers, which are designed to combine disks into one large storage.

Fujitsu controller

Among the most well-known models of RAID controllers from Fujitsu are the following:

  • Fujitsu D3216
  • Fujitsu D3307
  • Fujitsu 9211
  • Fujitsu PRAID EP580i

Fujitsu controllers support the following array levels: RAID0, RAID1, RAID5, RAID6, RAID50, RAID60, and RAID10.

Possible reasons for data loss on an array created using a Fujitsu controller

  1. Fujitsu controller failure - in this case, your array becomes completely unavailable. Often, you simply cannot get into the control panel from the array; the disks do not show any signs of life.
  2. File system failure - in this case, you can most likely get to the array control panel, but you receive some errors about malfunctions and the inability to access data.
  3. Failure of more disks than redundancy allows. If, for example, you are dealing with a RAID5 array and one drive fails, then you can still work with the array and only see warnings that you need to replace the drive as soon as possible. If two disks fail, then the data becomes unavailable to you. Data recovery is impossible, first you need to repair at least one of the disks.

How to recover data from a Fujitsu array yourself using software

In all cases of data loss on an array built on a Fujitsu controller, except for the failure of more disks than redundancy allows, you can try to recover the data yourself. And after that, in case of failure, consider the possibility of using the services of a special data recovery service. In the case of data recovery from an array, the entire recovery process consists of two stages:

  1. Restoring array parameters.
  2. File system recovery.

To recover data from a Fujitsu RAID array, you will need:

  1. Disconnect the drives from the Fujitsu controller. Be sure to label the disks and remember which disk was inserted into which connector from the Fujitsu controller.
  2. Connect the disks from the array to the Windows computer. It is recommended to connect the drives directly to the motherboard. However, if there are not enough ports on the motherboard, you can use special USB-to-SATA adapters.
  3. Check all connections carefully and turn on the computer.
  4. Download, install and run ReclaiMe Free RAID Recovery.
  5. Select all drives from the array and start scanning the RAID type you used. If you don't remember what type of array was used, you'll have to spend extra time because you'll have to brute-force.
  6. RAID5 recovery
  7. Wait until the program detects the array configuration.
  8. RAID recovery output options
  9. Next, we proceed to the second stage of recovery. In the ReclaiMe Free RAID Recovery window, select the “Run ReclaiMe to recover files” option. If ReclaiMe File Recovery is not installed on your computer, you will be offered to download it. If the software is installed, it will immediately open in RAID recovery mode.
  10. In the ReclaiMe software window, select a volume from the array and click Start.
  11. ReclaiMe RAID mode
  12. Wait until you receive a message that “Initial scan is completed” and start checking the recovery result.
  13. If the data is displayed correctly in the Preview window, then buy an Ultimate license.
  14. ReclaiMe scans RAID
  15. Prepare additional space where you will copy the recovered data and save all the data you need.

If ReclaiMe Free RAID Recovery was unable to restore the array configuration or the recovered data is not displayed correctly, then please contact us and we will try to help.
