7.7.1 Maintenance Mode
If you have no internal NSA volumes (disks), then the NSA is in Maintenance Mode. When
the NSA is in this mode you cannot create users, groups or shares on the NSA. You must first
go to the Storage > Disk screen and create an internal volume (assuming you already have an
internal disk installed).

You need to have at least one internal hard disk installed and an internal

7.7.2 External Disks
You may connect USB storage devices that support the following file systems to the NSA.
• Windows File Systems: NTFS (read only), FAT32 and FAT16.
If your USB storage device uses a NTFS file system, then the NSA can read files from it, but
cannot write files to it. If you want to be able to write files to that storage device, then you
should back up all data on the device (to an internal drive for example) and then click the
Initialize icon for the NSA to create an XFS volume on the (external) hard drive. You can then
both read and write to that hard drive and restore your data to it.

Although the NSA can read previously-stored files and folders using double-
byte characters (such as Chinese), it does not allow you to write new ones to
an external drive using double-byte characters.

7.7.3 Disk Replacement Restrictions
See the Quick Start Guide for information on replacing disks in the NSA. When replacing a
disk in a degraded or down RAID volume, the new disk must be at least the same size or
bigger than the other disks that are already in the RAID volume, so as all data in the volume
can be restored.
disk in a degraded or down RAID volume, the new disk must be at least the same size or
bigger than the other disks that are already in the RAID volume, so as all data in the volume
can be restored.
For example, if you have RAID with 250 GB disks, you must put in a 250 GB or bigger disk as
a replacement in order to restore all original data in that volume. If you put a bigger disk, the
extra space on the disk will not be used.
