File System
Select the file system you want the new volume to use. If you plan to also 
use the USB device with another computer, it is recommended that you 
select the file system that the other computer uses.
Windows file systems
fat32: Newer, and more efficient than FAT16. Supports a volume size 
of up to 2 TB (Tera Bytes) and individual file sizes of up to 4 GB.
fat16: Compatible with older Windows operating systems. Supports 
volume and file sizes of up to 2 GB.
ntfs: The newest Windows file system.
Linux file systems
ext2: Older file system.
ext3: The same as EXT2, but adds a journaled file system and is more 
robust.
reiserfs: Offers better performance for small files.
xfs: Offers good performance for larger files. You can also have the 
NSA encrypt a volume that uses the xfs file system.
Encrypted
Select this check box and an option from the drop-down list box to encrypt 
the volume. This option is only available when you create a volume using 
the xfs file system.
The NSA automatically locks an encrypted volume if the NSA restarts or 
loses power or the disk is removed.  An administrator can also manually 
lock the volume. Once a volume is locked, no one can use it again until an 
administrator unlocks it.
password: Select this option to manually enter a password for unlocking 
this volume. You can also enter a password prompt. You will need to 
manually re-enter the key every time the NSA restarts.
USB key: Select this option to have the NSA create a password for 
unlocking the volume and store the password on (another) connected 
USB device. Note that if the volume is later locked, the NSA automatically 
unlocks it if the USB device containing the key is inserted when the NSA 
restarts.
At start up, if a USB key is inserted, the NSA automatically unlocks any 
volumes encrypted by it.
Password
The password fields display if you choose to encrypt the volume by 
manually entering a password. Enter a password for encrypting the 
volume.
Password (Confirm)
Re-type the password to make sure you entered it correctly.
Password Prompt
Enter a hint to help you recall the password if you forget it.
USB Key
The USB field and button display if you choose to encrypt the volume by 
USB key. Select a USB key device that you created previously or select a 
USB device that you want to make into a USB key.
If the USB device is not already connected, connect it and click the 
Refresh icon.
The NSA’s upper USB port is USB1 and its lower USB port is USB2
It is recommended that you use a USB device to store a volume key only 
and not also use it for storage.
