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 8 GB capacity
- A Windows PC
Recovering The NAS
You can recover your NAS by first creating a USB boot drive 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:
Create a USB boot drive
- Download Rufus.
- Download the NAS system images below corresponding to the NAS model:
- Open Rufus.

- Under Device Properties > Boot Selection, click Select.
- Select the downloaded NAS system image for TS-885eU / TS-885eu-RP.
- Click Open.
- Click Start.
Rufus formats the USB drive and installs the NAS system image onto the USB 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.
Use the USB boot drive to recover the NAS
- Power off the NAS.
- Remove all drive trays.
- Connect the USB boot drive to a rear USB port of the NAS.

- Power on the NAS.
The NAS starts recovering the firmware with the USB boot drive. It will take around 10 minutes to complete the recovery process. Once it is done, the NAS pows off automatically. If the NAS does not power off after 15 minutes, the recovery process has failed. You can try it again or you may contact QNAP technical support. - After the NAS firmware process is finished, remove the USB boot drive from the NAS.
- Power on the NAS.
Qfinder Pro can now find your NAS.
Install the latest firmware version on your NAS with Qfinder Pro
- Download and install Qfinder Pro.
- Open Qfinder Pro.
- Locate your NAS in the device list.
- Right click on your NAS.
- Select Update Firmware.
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 the NAS User Guide available 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 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.

概述
本常見問題解答說明瞭如何在您的 NAS 無法啟動時手動恢復。此常見問題解答僅適用於上面列出的 NAS 型號。
NAS 恢復要求
要恢復 NAS,您需要以下物品:
- 一個至少 8 GB 容量的空 USB 驅動器
- 一臺 Windows 電腦
恢復 NAS
您可以透過首先建立一個 USB 啟動驅動器來恢復基本的 NAS 功能,然後使用 Qfinder Pro 更新韌體。如果恢復過程中的任何部分失敗,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:
建立 USB 啟動驅動器
- 下載 Rufus 。
- 下載 TS-855eU / TS-855eU-RP 的 NAS 系統映像 。
- 開啟 Rufus。
- 在 裝置屬性 > 啟動選擇 下,點選 選擇。
- 選擇下載的 TS-885eU / TS-885eu-RP 的 NAS 系統映像。
- 點選 開啟。
- 點選 開始
Rufus 會格式化 USB 驅動器並將 NAS 系統映像安裝到 USB 驅動器上。
警告
格式化 USB 快閃記憶體驅動器將擦除其所有現有資料。如果您有要保留的資料,請先將資料複製到您的電腦,然後在格式化 USB 快閃記憶體驅動器後,將資料複製回來。
使用 USB 啟動驅動器恢復 NAS
- 關閉 NAS。
- 移除所有硬碟托架。
- 將 USB 啟動驅動器連線到 NAS 的後部 USB 埠。

- 開啟 NAS。
NAS 開始使用 USB 啟動驅動器恢復韌體。恢復過程大約需要 10 分鐘完成。完成後,NAS 將自動關閉。如果 NAS 在 15 分鐘後仍未關閉,則恢復過程失敗。您可以再試一次或聯絡 QNAP 技術支援 。 - 在 NAS韌體過程完成後,從 NAS 中移除 USB 啟動驅動器。
- 開啟 NAS。
Qfinder Pro 現在可以找到您的 NAS。
在您的 NAS 上安裝最新的韌體版本與 Qfinder Pro
- 下載並安裝 Qfinder Pro 。
- 開啟 Qfinder Pro 。
- 在裝置列表中找到您的 NAS。
- 右鍵點選您的 NAS。
- 選擇 更新韌體。
將開啟 更新韌體 視窗。 - 選擇 自動更新韌體到最新版本。

- 點選 開始。
NAS韌體將更新到最新版本。
安裝硬碟
進一步故障排除
- 如果無法成功完成本指南中的步驟:
您的 NAS 需要由合格的硬體技術人員進行實體維修。 - 如果您能夠使用 Qfinder Pro 在您的 NAS 上安裝最新的韌體版本,但在安裝硬碟後,NAS 無法啟動:
