Chieftec CEB-2355S User Manual

1

**Please read this manual carefully before you use the product**

Description：

The CEB-2355S is a multifunction storage device designed in a special
body structure, which can be simply connected to the PC by either
USB2.0 or eSATA. It supports 2 SATA HDDs with entirely screw free
patent design for easy installation and is additionally equipped with ball
bearing fans to keep the HDDs cool !!

MODE:

z Dual Mode: 2 HDDs appear on your computer and can be used

/ accessed simultaneously

z JBOD Mode: Your computer displays 1 HDD with the capacity

of two HDDs combined

z Raid 0 Mode**: This mode involves no redundancy and splits

the files equally into each HDD. The advantage of this mode is
the data transfer speed, but the disadvantage is data might be
damaged if one of the HDDs is defect.

z Raid 1 Mode** (mirroring): One HDD has its data duplicated

on another HDD. If either drive fails, the other continues to
function as a single drive and thus provides full redundancy.

z SAFE50 Mode*：½ (50%) of the HDD volume is used for

mirroring and the rest is used for Raid 0.

z SAFE33 Mode*：1/3 (33%) of the HDD volume is used for

mirroring and the rest is used for Raid 0.

* The SAFE33 & SAFE50 modes only perform when your motherboard
/ PCI card contains Silicon IC
** Some WD (Western Digital) Desktop Edition HDDs do not support
the RAID function. Please check the website below for more
information.

not either contain Silicon Image IC controller or have the port
multiplier function, it is very important to know that there is only
JBOD mode can be used.

Partitioning Volumes

MS Windows

Important: Before reconfiguring a volume, back up your
data.

1. Right-click the My Computer icon on your desktop and

10

select Manage from the pop-up window.

2. Select Disk Management under Storage to open the
Windows Disk Manager. This example below illustrates the
JBOD mode, which concatenates the capacity of all hard
drives connected to the CEB-2355S

Every Disk should appear with the word “Basic”, a size value
that shows the available storage capacity, and a status of
“Online”. Instead of Basic, a disk could appear as Unknown,
Dynamic, or Not Initialized.

If a disk appears as “Unknown”, right-click the disk icon and
select Write Signature. A window opens with the selected disk
(All Unknown disks may appear in this window). Make sure
the box next to each disk is checked and click OK. The disk
should be marked as a Basic disk now.

If a disk appears as “Dynamic”, right-click the disk icon and
select Rever to Basic disk. Within a few seconds the disk
should be marked as a Basic disk.

If a disk is marked “Not Initialized”, right-click the disk icon
and select Initialize Disk. An additional dialog box appears
allowing you to select which disks to initialize.
