The NAS supports external USB and eSATA storage devices for backup and data storage. Connect the external storage device to a USB or an eSATA interface of the NAS, when the device is successfully detected, the details will be shown on this page.

 

Storage Information

 

Select a storage device and click "Storage Information" to check for its details. The number of USB and eSATA interfaces supported varies by models. Please refer to http://www.qnap.com for details. It may take tens of seconds for the NAS server to detect the external USB or eSATA device successfully. Please wait patiently.

 

Format

 

The external storage device can be formatted as EXT3, EXT4, FAT32, NTFS, or HFS+ (Mac only) file system. Click "Format" and select the option from the drop-down menu.

 

Note: Starting QTS 4.1, labeling is supported for external USB devices. To edit the label of an external USB drive, please first format it as EX3 and EX4 and click "Storage Information" to edit its label. The label changed will become the shared folder name of this external USB device in the File Station (in the File Station, an USB external device will appear as a shared folder.) Note that this feature is only supported by the x69, x70 and x79 NAS models.

 

The NAS supports external drive encryption. To encrypt an external storage device, click "Encryption". Select the encryption method: AES 128-, 192- or 256-bit and enter the password (8-16 characters). Select "Save encryption key" to save the password in a hidden location on a hard drive of the NAS. The NAS will unlock the encrypted external storage device automatically every time the device is connected. Click Format to proceed. Click "OK" and all the data will be cleared.  The device will be "Ready" after disk initialization.

 

Note: For disk volumes larger than 2TB, it is recommended to format them to the EXT4, NTFS, or HFS+ file system.

 

Eject

 

"Eject" offers two different options. "Disconnect disk partition" allows you to remove a single disk partition or a disk drive in a multi-drive enclosure. "Remove device" allows you to disconnect external storage devices without the risk of losing any data when the device is removed. First choose a device to eject, click "Eject" and then to disconnect the disk partition or remove the device.

 

Note: To avoid potential data loss, please always use the hardware removal function in the operating system before removing your external storage device (for a Windows PC, please use the "Safely Remove Hardware" function; for a Mac, please use the "Eject" icon; for QTS, please use the "Eject" button.)

 

Encryption Management

 

If an external storage device is encrypted by the NAS, the button "Encryption Management" will appear. Click this button to manage the encryption password/key, or lock or unlock the device.

 

Locking the device

1.To lock an encrypted external storage device, click "Encryption Management".
2.Select "Lock this device" and click "Next".
3.Click "Next" to lock the device.

 

Note: The external storage device cannot be locked if a real-time or scheduled backup job is running on the device. To disable the backup job, go to "Control Panel" > "Applications" > "Backup Station" > "External Drive".

 

Unlocking the device

1.To unlock an encrypted external storage device, click "Encryption Management".
2.Select "Unlock this device". Click "Next".
3.Enter the encryption password or upload the key file. Select "Save encryption key" to save the password in a hidden location on a hard drive of the NAS. The NAS will unlock the encrypted external storage device automatically every time the device is connected. Click "Next".

 

Managing the encryption key

1.To change an encryption password or download an encryption key file, click "Encryption Management".
2.Select "Manage encryption key". Click "Next".
3.Select to change the encryption password or download the encryption key file to the local PC. Click "Next".

 

Data Sharing

 

Disk usage settings for 1-drive models. Select one of the following settings for an external storage device connected to a 1-drive NAS:

Data sharing: Use the external drive for storage expansion of the NAS.
Q-RAID 1: Configure the external drive and a local hard drive on the NAS as Q-RAID 1. Q-RAID 1 enables one-way data synchronization from the NAS to the external storage device but does not offer any RAID redundancy. Note that the external drive will be formatted when Q-RAID 1 is executed.

 

After Q-RAID 1 has been executed once, the NAS data will be automatically copied to the external storage device whenever it is connected to the NAS.

 

Note:

Only one external hard disk can be set as Q-RAID 1 at one time.
The maximum capacity supported for Q-RAID 1 is 2TB.
It is recommended to use an external storage device of the same capacity as the internal hard drive of the NAS. If the storage capacity of the external storage device is too small to synchronize with the internal hard drive, the device can only be used for data sharing.
The HD Station will reboot when external devices are unmounted.
