1.2 Firmware
Before you can start using your NSA, you have to install the firmware on the hard
disk. Use the NAS Starter Utility to do this. See
Chapter 2 on page 29 for more
information on the NAS Starter Utility.

The firmware includes the features mentioned in Section 3.6.2 on page 53 . You
can use the Package Management screen ( Chapter 10 on page 211 ) to install
more applications from a web location (specified in the firmware) to your NSA.
1.3 Hard Disk
Your NSA has one internal hard disk bay and one external SATA (eSATA) port.
This allows you to connect one internal SATA (Serial Advanced Technology
Attachment) hard disk and one eSATA hard disk (optional).
After installing the firmware on the internal hard disk, it is configured as a JBOD
volume by default. JBOD stands for Just a Bunch Of Disk and in this storage
method, all disk space is used for your data - none is used for backup. If you are
not using an eSATA hard disk, JBOD is the only storage method you can use.
If you attach an eSATA (external SATA) hard disk, you can create a RAID 1
volume. RAID 1 allows data recovery in case your hard disk fails. To create a RAID
1 volume on the NSA, you must delete the JBOD volume created by the firmware.
Refer to
Section 7.4 on page 147 for the Storage screen where you can create
the RAID 1 volume.
The eSATA hard disk can also be configured as a JBOD or a PC Compatible
Volume. See
Section 7.5.2 on page 154 for more information on these storage
methods.
Note that both SATA and eSATA hard disks are treated as internal or SATA
volumes in the Storage screen (
Section 7.4 on page 147 ). Any hard disk
connected to the USB port(s) is considered an external or USB volume.
