Chapter 7: Tips and Tricks
USB and eSATA Storage Expansion
The 1U4500 supports external USB hard disks through its three USB ports. Once
a USB hard disk has successfully mounted, the entire volume will be copied
automatically to the default USB HDD folder. The 1U4500 supports up to 6 USB
external storage devices. All file names on the USB disk volume are case sensitive.
The 1U4500 also supports eSATA hard disks with its eSATA port.
Before attaching an eSATA or USB disk drive to 1U4500, you have to partition
and format it on a desktop computer or a notebook first. The attached device will
be located at \\192.168.1.100\usbhdd\sdf1 where 192.168.1.100 means the
IP address of 1U4500 and sdf1 stands for the first partition on disk #6, the
eSATA or USB disk drive. If it is an NTFS partition, NAS users can open or copy
files from \\192.168.1.100\usbhdd\sdf1 but cannot add new files or modify
existing files.
Adding a Spare Disk
With a RAID 5 array, you can add a spare disk after the initial RAID is setup. To
add a spare disk, follow the steps below:
1. On the RAID Configuration Screen, tick the checkbox of the hard disk
you wish to designate as a spare disk.
2. Click Add Spare. The system automatically rebuilds.
Target USB
1U4500 can operate in dual mode. When connecting to a regular USB disk or
thumb drive, 1U4500 is acting as USB host. When connecting to a PC thru its USB
Type B connector on the back panel, 1U4500 can act as a USB Mass Storage
device. This feature allows the user to transfer files without using a network
connection.
When you create RAID, you can assign a portion of space on the RAID to be used
as USB disk. When connecting 1U4500 to a PC using the supplied USB A to B
cable, the PC will recognize this space as an unformatted disk. At this point, the
PC can format this portion of disk and create file system on it. Since this disk is
created on the RAID, it will be protected by the RAID level you select.
NOTE If you want to write to an USB storage device, the file system must be FAT32.

When RAID is removed or damaged, all the data on the Target USB device will be
deleted.
