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.
If you want to write to an USB storage device, the file system must be
FAT32.

Adding a Spare Disk
With a RAID 1, RAID 5, RAID 6, or RAID 10 volume, 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 disk will be configured as a spare disk. The system
automatically rebuilds the spare disk when one of the disks in the RAID set
fails.
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 disk. This feature
allows user to transfer files without using 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.
When RAID is removed or damaged, all the data on the Target USB
device will be deleted.
