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 1 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 your NAS, perform the following steps:
Prepare the NAS and verify the state of the DOM
- Power off the NAS.
- Remove all drive trays.

- Connect the USB keyboard to a USB port on the NAS.

- If the NAS has a VGA or HDMI port, connect the NAS to a monitor with a corresponding HDMI or VGA Cable.
- 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?
- Power on the NAS
BIOS information is displayed including the version and release date of the BIOS. - 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
- Download and install the Windows version of UNetbootin.
- Download the following Linux ISO file: http://distro.ibiblio.org/damnsmall/current/dsl-4.4.10-initrd.iso
- Connect the USB drive to a USB port on your PC.
- Format the USB drive as FAT32:
- Open File Explorer.
- Open File Explorer.
- Locate the USB drive.
- Locate the USB drive.
A context menu appears. - Click Format.
The USB Format window appears. - Under File system, select Fat32.

- Click Start.
A confirmation window appears explaining that all data will be erased on the flash drive.
Warning
Formatting a USB flash drive will erase all its existing data. If you have data on the USB flash drive you want to preserve, copy the data to your PC first, then after formatting the USB flash drive, copy the data back.
- Open Unetbootin.
- For Distribution, select Damn Small Linux.
- For Diskimage, select ISO.
- Click "...".
- Locate and select the downloaded Linux ISO file from the previous steps.
- Click OK.
- For Type, select USB Drive.
- Click OK
UNetbootin installs the Linux ISO onto the USB drive.

- After installation is completed, click Exit.
- Download the NAS system image below corresponding to the NAS model:
- TS-239 Pro

- Rename the NAS system image to "dom.img".
- Copy "dom.img" to the root folder of USB drive.
The USB drive can now be used as a USB boot drive to recover your NAS system's DOM.
Use the USB boot dive to recover the corrupted DOM
- Power off the NAS.
- Connect the USB drive to a USB port on the NAS.
- Power on the NAS and while the NAS is starting up, press the F11 key repeatedly until the NAS displays the BIOS menu.
Tip
The F11 key must be pressed at a specific time to trigger the BIOS menu. Pressing the F11 key repeatedly helps ensure the key will be pressed at the correct time.

- Under Boot Device, select the USB drive.

Warning
Do not select USB DISK MODULE PMAP.
- On the following menu, select Default for monitor setting.

- Press Enter.
The NAS starts up and the following window is displayed:

- Press Ctrl+Alt+Del to open the command line.
- Input the following command:
sudo su
fdisk –l
The following partitions are present:
| Partition | Description |
|---|
| /dev/sda | The USB boot device |
| /dev/sdb or /dev/hda | The DOM (Disk On Module) which is either 126 MB or 515 MB in size |

- Enter the following commands:
mkdir usbdrive
mount /dev/sda1 /home/dsl/usbdrive
cd /home/dsl/usbdrive
- Enter the following command:
cp dom.img {0}
| Variable | Description |
|---|
| {0} | The path of the DOM. Either "/dev/sdb" or "/dev/hda" |
The NAS system image "dom.img" is copied from USB boot drive to the DOM.
- Reboot your NAS with the following command:
reboot

The NAS starts up correctly and Qfinder Pro can now find your NAS.
Update the NAS firmware (For firmware versions 1.x.x)
If the NAS system image downloaded above is version 1.x.x, then you must update your firmware to a newer version to complete the recovery process. Follow the steps below to update your firmware:
- If the NAS is a TS-239, TS-439, TS-439U, TS-509, TS-639, TS-809, TS-809U, SS-439 or SS-839, follow the steps in this tutorial:
http://wiki.qnap.com/wiki/NAS_Firmware_Update_When_No_HDD(s)_Installed - For all other x-86 based NAS, use Qfinder Pro to update the firmware:
- Download and install Qfinder Pro.
- Open Qfinder Pro.
- Locate your NAS in the device list.
- For details on using Qfinder Pro, see Qfinder Pro Help.
- Select Update Firmware and login with the default admin credential.
The Update Firmware window opens. - Select Automatically update the firmware to the latest version.

- Click Start.
The NAS firmware will be updated to the latest version.
Install hard drives
- After the firmware is updated, perform the following steps to install hard drives:
- Attach the hard drives to the drive trays.
- Insert the drive trays into the NAS.
For details on installing hard drives, see your NAS User Guide availble for download from Download Center. - 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.
- If the hard drives are new, you can continue to initialize the NAS. For initializing QTS or QuTS hero on your NAS, see the following:
- QuTS hero Initialization (5.0.x)
- 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.

概覽
本常見問題解釋瞭如果您的NAS無法啟動時如何手動恢復。本常見問題僅適用於上述列出的NAS型號。
NAS恢復要求
要恢復NAS,您將需要以下物品:
- 一個至少1 GB容量的空USB驅動器
- 一個USB鍵盤
- 一條HDMI線,或一條VGA線
- 一臺Windows PC
- 一臺顯示器
恢復NAS
您可以透過首先建立一個啟動盤來恢復基本的NAS功能,然後使用 韌體 更新 Qfinder Pro 來恢復您的NAS。如果恢復過程的任何部分失敗,請參見下面的進一步故障排除。要恢復您的NAS,請執行以下步驟:
準備NAS並驗證DOM的狀態
- 關閉NAS電源。
- 移除所有驅動器託盤。

- 將USB鍵盤連線到NAS上的USB埠。

- 如果NAS有VGA或HDMI埠,則使用相應的HDMI或VGA線將NAS連線到顯示器。
- 如果NAS既沒有VGA也沒有HDMI埠,但有控制檯埠,則透過控制檯埠將NAS連線到顯示器。詳情見,如何使用 3.5mm 控制檯埠進入 BIOS 和控制檯?
- 開啟NAS
顯示BIOS資訊,包括BIOS的版本和發布日期。 - 等待DOM(磁碟模組)啟動。
如果DOM未能完全啟動,則表示DOM資料已損壞,您可以繼續按照本指南進行NAS恢復。
建立USB啟動驅動器
- 下載並安裝 UNetbootin 的Windows版本。
- 下載以下Linux ISO檔案: http://distro.ibiblio.org/damnsmall/current/dsl-4.4.10-initrd.iso
