ACD-763XX is a reliable and affordable solution for RAID 1 disk mirror and backup
disk . The RAID box mirrors data to two hard drives in RAID box simultaneously, and
delivers optimized performance. And featuring intelligent online recovery, the RAID
box lets you hot swap a failed hard drive and automatically rebuild the data to the
new hard drive without any system down time. The RAID box also provides the
backup disk for time setting to backup RAID1 disk to prevent the system data fails ,
the ACD-763xx RAID box support system interface for traditional IDE (ACD-76300)
(Also known as P-ATA) and SCSI (ACD-76301) and SATA(ACD-76302)

RAID level 1 concept (Disk mirroring)
RAID is an acronym of Redundant Array of Independent/Inexpensive Disks.RAID1 is
one of several RAID levels. RAID 1 also known as “Disk mirroring”. Data are written
to both disks simultaneously. RAID1 provides both high reliability and continued
data availability in the event of failure of an array member. When a RAID1 member
disk fails, array management simply directs all application requests to the
remaining disk. RAID1 is suitable for data which reliability requirements are
extremely high, or for data to which high performance access is required.
Disk backup function description
The extra advantage of ACD-76300/301/302 is disk backup function.
ACD-76300/301/302 offer third disk except the pair of RAID 1 group for full disk
back-up automatically or manually, and it is schedulable by Windows-base GUI
program through its built-in RTC (Real-Time Clock).the schedule can be set as per
month, per week or day as user desired. This function reduces the maintain effort on
back-up data from system manually, also preventing risk from any operating system
and software crash issues.

Launch StorConn
1. To launch StorConn, go to Start > Programs > StorConn> StorConn or double
click on StorConn icon on Desktop.
2. The Detect Option dialog box will appear
prompting you to scan the RAID box. StorConn
supports in-band and out-band connection.
Select “No” for not detect COM port device if
you want to use in-band connection.
Note
StorConn can obtain RAID system information through
the RS232 (COM port) connection. The program always
checks first for the IDE connection, then the RS232
connection. If both connections are present, COM port
is used.

from the RAID box via RS232.
The Detect Process dialog box shows the progress of
the system’s detection of RAID box.
2. Once the scan is finished, The StorConn RAID
Information dialog box appears. This identifies the
properties of the RAID box detected and its current
status.
RAID information includes:
Serial Number: the serial number of the RAID box.

Configure the SCSI channel
The Default SCSI configuration as
shown on the figure. The default SCSI
ID is 6.
If you intend to configure the SCSI
channel to different ID number, please
refer the table. And leave others setting
as default if unnecessary.
*The SCSI ID 7 usually reserved for
SCSI host controller, please avoid
using ID 7 for ACD-76301 box for
preventing the ID conflict.

Install ACD-76300/301 into system
Follow the following instructions to establish the connection.
1. After RAID box is fully configured.
2. Power down your host computer.
3. Mount the RAID box into the system.
4. Connecting the SCSI/IDE cable from system computer to RAID box.
5. Connecting DC power from system power output to the DC power input
connector of power-delay module.
6. Connecting power cable that attached with package from end of DC power
output of power-delay module to RAID box.
(Please refer to below figure for instruction 5 and 6.)
7. After completing the above steps. Refer to next section for Starting using the
RIAD box.
Start using RAID box
Application 1: Two new disk drives.
1. Insert both hard drives into the RAID box.
2. Power on the host computer.
3. After system boot up, the RAID box will be recognized by host system.
And system treats it as a single disk.
4. Partition and format the array under OS before it can be used.
Application 2: Installing one hard drive with data and one new
hard drive.
1. The new hard drive must be the same capacity or larger capacity than
the hard drive that with data.
2. Insert hard disk that with data into the top slot and leave bottom Slot
empty. This identifies the disk with data as the source drive. (The host
computer must be in power-off status.)
3. Power on the host computer.
4. Insert the new hard drive into bottom slot. This identifies the newly
inserted hard drive as a target disk.
5. The RAID box will immediately begin mirroring the data from the
source hard drive to the new hard drive in bottom slot. Any old data on
the newly inserted hard drive will be lost, and is overwritten with the
mirror image of the source drive.
Note
If you have installed non-identical hard drives, your
computer will recognize RAID box as a single hard disk
with a capacity equal to the smaller hard disk drive
installed in the RAID box.
