Overview

This FAQ explains how to manually recover your NAS if it fails to start up. This FAQ only applies to the NAS models listed above.

NAS Recovery Requirements

To recover the NAS, you will need the following:

  • An empty USB drive of at least 4 GB capacity
  • A USB keyboard
  • An HDMI cable, or a VGA cable
  • A Windows PC
  • A monitor

Recovering the NAS

You can recover your NAS by first creating a boot disk to restore basic NAS functionality and then updating the firmware with Qfinder Pro. If any part of the recovery process fails, see Further Troubleshooting below. To recover the NAS, perform the following steps:

Prepare the NAS and verify the state of the DOM
  1. Power off the NAS.
  2. Remove all drive trays.
  3. Connect the USB keyboard to a USB port on the NAS.
  4. If the NAS has a VGA or HDMI port, connect the NAS to a monitor with a corresponding HDMI or VGA Cable.
  5. If the NAS does not have either a VGA or HDMI port but does have a console port, then connect the NAS to a monitor via the console port. For details see, How do I enter BIOS and Console with 3.5mm Console port?
  6. Power on the NAS
    BIOS information is displayed including the version and release date of the BIOS.
  7. Wait until the DOM (Disk-on-module) starts up.
    If the DOM fails to start up completely, then the DOM data has been corrupted and you can continue following this guide to recover the NAS.
Create a USB boot drive
  1. Download Rufus.
  2. Download and install the version of Clonezilla that corresponds to the NAS model:

      For details on installing hard drives, see the NAS User Guide available for download from Download Center.
    3. If the hard drives are not new, the firmware must be updated again while the hard drives are installed. For details, see Updating the NAS Firmware Using Qfinder Pro in How to search and manage a QNAP NAS using Qfinder Pro.
    4. If the hard drives are new, you can continue to initialize the NAS. For details on initializing QTS or QuTS hero on your NAS, see the following:
      1. QuTS hero Initialization (5.0.x)
      2. QTS Initialization (5.0.x) 

Further Troubleshooting

  • If the NAS BIOS failed to display:
    Your NAS needs to be physically serviced by a qualified hardware technician.
  • If the steps of this guide could not be successfully completed:
    Your NAS needs to be physically serviced by a qualified hardware technician.
  • If you were able to install the latest firmware version on your NAS with Qfinder Pro but after installing the hard drives, the NAS will not boot up:
    The hard drives are faulty and need to be replaced. A NAS will fail to start up if the hard drives are faulty.
