ARAID 1500 and 2000 Operations Overview
ARAID 1500 General <IMPORTANT>
IDE Drives: Set both IDE hard disks in upper and lower trays to “Master” or “Single
Drive” mode allowing the ARAID to detect and recognize the hard disks in
the trays.
NOTE: “Cable Select” is the default jumper setting for most new IDE hard disks. You must change
the jumper to “Master” mode, or otherwise ARAID won’t detect it.
ARAID 1500 and ARAID 2000 General
Default Mode: ARAID 1500/2000 default operation is UDMA. If it cannot work with the
host SATA on your PC in this mode, it will automatically switch to PIO
mode 4 or a lower drive speed.
Cooling: ARAID 1500/2000 is equipped with a 70mm cooling fan providing
adequate ventilation for hard disk operation at 10,000 rpm. Please check
and remove any obstructions in the computer system that may be
blocking air to and from the ARAID disk array.
Drive Selection: ARAID works with all drives. We recommend using two new matching
drives but two identical drives will work. ARAID is designed with a strict
EIDE command set and accurate to work on any operating system without
the need of a device driver or RAID I/O controller board.
ARAID 1500 and 2000 RAID 1 Users
Default mode: When ARAID is set at RAID 1 mode, its front panel operation mode switch
is set to Default position for ordinary disk mirroring operation.
One Drive Operation: ARAID can operate with only one drive in the upper bay. When the front
panel operation mode switch is set to Single, ARAID will only access to
Mobile Rack1 (Upper Bay) disk, and the mirror function is disabled.
Changing Modes from Single to Default: ARAID will automatically mirror contents from the
Upper tray to Lower tray when you switch from Single to Default mode
(Performing a manual Mirror-On-Demand).
ARAID 1500 and ARAID 2000 RAID 0 Users
Mode Selection: When ARAID works at RAID 0 mode, the front panel operation mode
switch must be always set to Default.
Additional Notes for RAID 0 Users
z
When ARAID is set at RAID 0 mode, it requires two disks to operate with. ARAID will not
work with one single disk installed at RAID 0 mode.
z
z
Always place the switch in the “Default” position for RAID 0 operation.
Never place the switch in the “Single” position or switch it from “Single” to “Default”, or you
will risk losing all RAID 0 data.

ARAID 1500 or 2000 Operational Tests
ARAID is designed with strict compliance to the SATA and EIDE (Parallel ATA) command set
and timings. ARAID is a self-contained RAID storage subsystem that connects to any
operating system and motherboard without requiring a device driver or I/O board. Please refer
to the BIOS Setup in the Q&A section for complete details on how to optimize ARAID for your
PC. You can also contact your Accordance dealer or contact Accordance at
RAID 1 Basic Operation Test – Mirroring
1. Prepare your PC or motherboard, two identical hard drives and operating system image.
2. Load the operating system to one S-ATA or IDE hard drive (source disk).
3. Attach the source disk (SATA or IDE) with the OS to the upper bay of the ARAID device.
4. Attach the ARAID device to the SATA port on the target PC.
5. Run ARAID as a single disk to the PC making sure that front panel operation mode switch
is set to Single.
6. Once the source disk operation is confirmed, then set the operation mode from Single to
Default and install a target disk into the lower tray. You can do this while the system is
powered since ARAID supports hot-swapping. ARAID will then automatically detect the
presence of the second disk and start disk mirroring functionality with Auto Rebuild.
7. You have passed the basic compatibility test are now executing RAID1 maintaining
concurrent data on both drives.
RAID 1 - Auto Rebuild Function Test
1. The ARAID Auto Rebuild Function feature provides automated disk copying of Source
disks to Target disks. Rebuilds can be done while the computer is in use or on off-line.
2. Refer to the Auto Rebuild Test (ARF) section for complete instructions and hardware
compatibility.
RAID 0 Basic Operation Test - Striping
1. Prepare your PC or motherboard, two identical hard drives and operating system image.
2. Set the front panel operation mode switch to Default.
3. Install two identical hard disks into the upper bay and lower bay.
4. ARAID RAID 0 will perform striping allowing the PC to read and write to the two drives as
one disk.
5. Disk capacity is doubled and disk read/write performance will be improved 35% or
greater.

ARAID Questions & Answers
PC BIOS setup
Q: What type of hard drive should be selected in the PC BIOS setup?
A: If you are using two identical hard drives (same manufacturer and model) in your ARAID,
select HDD TYPE of AUTO.
If you replace a failed hard drive with a new disk with the same brand, and the same model
series, but with a larger capacity, select HDD TYPE: AUTO, as well.
If the replacement drive is larger than the surviving drive, it is imperative that you place the
smaller (surviving) drive in the upper bay, then boot the computer. When the operating system
is booted, insert the new larger capacity disk in lower bay and launch auto rebuild.
Power failure while disk rebuild is in progress
Q: What should I do if the power fails while auto-rebuild is in progress?
A: Just turn on the PC again, the disk rebuild will restart and continue, regardless of whether
you are rebuilding from primary to secondary (upper bay to lower bay) or rebuilding from
secondary. To primary (lower bay to upper bay).
The PC will boot from the source disk, whether it is primary or secondary, then it will
automatically resume the disk rebuild sequence without further user intervention.
Preventing and recovering from an unexpected virus attack
Q: How can I prevent or recover from a virus attack by utilizing Mirror-On-Demand function
provided by ARAID? (for RAID 1 users only).
A: Prevention is the most important factor in preventing a virus attack. Accordance
recommends the use of commercial grade anti-virus software and a hardware firewall.
Remember to check with the AV and firewall manufacturer’s website frequently for the latest
updates to their products.
If you find that you are infected, run the AV software first to clean or quarantine the virus.
Here are some other recommendations you can optionally use.
Method 1: Generate a grandfather/father/son, multi-generation backup Use the ARAID
on-the-fly disk rebuild and disk hot swap function to duplicate a clone
periodically as you require. Keep the archive of your generated backup disks
in safe place. If both disks in an ARAID array are affected by a virus, remove
them and replace with the latest unaffected archive disk and rebuild a clean
disk array in just minutes.
Method 2: Use Accordance the mirror-on-demand function on the front panel operation
mode switch to initiate a disk duplication whenever you need. While the
system is clean and virus-free, make sure to generate clone disks and keep
them in safe place.

Replacing and Upgrading Hard Drives
Q: What should I do if I need to replace a defective hard drive?
A:
1. To minimize the risk of losing mission critical data, make it a practice to keep a spare
hard drive of the same make and model for the next two years. Always restock your
spare inventory with new hard drive(s) of the same model whenever a defective hard
drive is replaced. These drives can be easily added to the ARAID disk array and rebuilt
by running the Auto Rebuild facility.
2. If your replacement drives are the same manufacturer as the original drives but are a
larger capacity, place the surviving drive in the upper bay where it will be designated as
the source drive. Boot the PC from the upper bay source drive. When the operating
system is ready to serve, insert the replacement drive into lower bay. The disk auto
rebuild sequence will now start. If it fails to start, switch the front panel operation mode
switch from “Single” to “Default” The BIOS HDD type can set to Auto in this case.
For normal operation, always put the smaller capacity drive in upper bay and larger
capacity drive in lower bay. Never place the larger capacity drive in the upper bay.
Tip: Label each tray with the disk capacity, brand, and model for future reference.
3. The BIOS of some older computers may only be able to access hard drives of 8GB or
less. In these instances, you must set the HDD TYPE in the BIOS to USER mode and
then key in the Head/Cylinder/Sector data which is printed on the drive label or
available from the manufacturer’s website.
4. CASE STUDY:
z
Company ABC uses two Western Digital WD800BBRTL (80GB) hard drives on one
ARAID disk array.
z
z
Company ABC should keep an inventory of spare WD800BBRTL hard drives.
Company ABC experiences a disk crash and has no more WD800BBRTL to replace.
Instead a new WD1200BBRTL (120GB) is available for replacement. For daily
operation, the smaller drive, the WD800BBRTL, needs to be put in Upper Bay and the
larger drive, the WD1200BBRTL, must be put in the Lower Bay as a mirrored couple.
In this scenario the mirror couple of WD80GB + WD120GB, its effective capacity is 80GB.
RAID 1 disk array capacity is always defined by the capacity of the smaller drive.
For Windows User ONLY:
z
If at some later point the WD800BBRTL malfunctions and the WD1200BBRTL is
the surviving drive, you can enlarge the WD1200BBRTL’s partition size from 80GB to
120GB by using a third party’s program, such as Symantec's Ghost. Then mirror it to
another WD1200BBRTL and realize a 120GB disk capacity.
