NAS data recovery after factory reset

“Factory reset” is a reset of all settings to those that were set by the manufacturer. This concept exists not only for NAS devices, but also for phones, tablets, and so on.

While the device is in use, errors appear and accumulate in the operating system that interfere with its normal operation. Resetting the data resets the operating system settings and removes software glitches and errors.

Typically, factory reset is done in the following cases:

  • Before selling the NAS device;
  • If some problem occurs on the device that cannot be corrected in other ways;
  • After updating the NAS device software.

Before doing a factory reset, the important recommendation is to copy all important data to another storage and check that you can access it.

However, very often, clients think that they had a copy of the data either in the cloud or on another device, did a factory reset, and then it turned out that the backup was either missing something, or it was simply No.

In addition, some manufacturers of NAS devices claim that a factory reset will not affect the user’s data in any way, but something went wrong and the person lost all data.

The good news is that there is a good chance to recover the original data. However, the data recovery process will take some time and may require the purchase of additional equipment and special software for NAS recovery.

How to recover data from a NAS device after a factory reset

  1. Remove all drives from the NAS device and label them according to the NAS bays.
  2. disconnect NAS disks
  3. Connect NAS drives to a computer running Windows. It is recommended to connect the drives directly to the computer, but if there are not enough ports, you can use USB-to-SATA adapters. To connect the drives, you may need to buy either additional SATA cables or USB adapters with power.
  4. Think about where you will copy the recovered data. If you only need to recover a couple of files, then this is not a problem, since they can be copied to a computer disk or flash drive. And if you need the entire amount of data stored on the NAS, then this can become a headache, as you may need to buy new drives.
  5. Download and install the NAS recovery software - ReclaiMe.
  6. In the list of devices from ReclaiMe, select the volume from the NAS device and start the scan.
  7. Select md-raid volume in ReclaiMe
  8. Wait until you receive a message that the initial scan is completed and start checking the recovered data using the Preview function.
  9. Check the quality of the recovery in ReclaiMe
  10. If the data is displayed correctly, buy the Ultimate license key and copy the data to the prepared storage.

Once you are sure that the recovered data can be opened, transfer it back to the NAS device.


if you haven’t found your NAS volume in the device list displayed by ReclaiMe, your RAID configuration is probably severely damaged. Before starting the NAS recovery, you need to recover the array configuration parameters using ReclaiMe Free RAID Recovery software .
