3. Hardware Requirements and Precautions
1. Computers or servers must be with SATA I, SATA II, or SATA III interface.
2. Hard drive must be with SATA I, SATA II, or SATA III interface.
3. The independent drive at the top cannot be set into RAID mode with primary or secondary drive.
It is an independent drive.
4. You are strongly advised to set the storage mode before using your iR2823/iR2824. (The default
setting is the RAID 1.)
5. Once the drive mode conguration has been completed, re-conguration using the same hard
drives to set the drive mode will result in complete data loss. If you must change the drive mode,
make sure to backup all data prior to the mode change.
6. A reboot is required after adding or changing RAID mode to ensure that the update is completed
to the new RAID mode.
7. iR2823 / iR2824 product allows user to simultaneously use the two dierent hard drives from two
dierent manufactures. However, if the user expects a better efficiency, we strongly recommend
the user to use the two hard drives from the same manufacturer.
8. Please make sure that the two hard drives are free from bad blocks or defects prior to installation
in order to avoid system crashes or data loss.
9. The actual storage capacity of iR2823 / iR2824 recognized by the system may dier from the total
capacity stated on the hard drives combined once the drives have been formatted.
10. It is highly recommended for user to back up important data contained within the iR2823 / iR2824
unit on a regular basis or whenever the user feels necessary to a remote or a separate storage
device. RAIDON will not be responsible for any lost of data caused during the use of the unit or
the recovery of the data lost.

5. RAID Mode Setting
After placing your two hard disks, turn on power and press UP Button, you are with the RAID Setting
mode. (Since the default setting is RAID 1 mode by factory, you do not have to reset RAID if you
want to use your iR2823 / iR2824 with RAID 1 mode.)
1. RAID 1 mode
1). Place two new hard drives into iR2823/iR2824.
We would strongly suggest you to use two identical hard drives to get the maximum memory
capacity. And if the capacities of your two hard drives are dierence, iR2823 / iR2824 only
recognizes the memory capacity at the small capacity hard drive.
2). Under RAID 1 mode, two hard drives will have the identical information as one from its mirroring
feature, therefore, even though one and only one of the two hard drives failed, iR2823 / iR2824
will still work ne and properly. Once you replace the failed hard disk with a new one, iR2823 /
iR2824 will automatically do rebuilding the data from the good one to the new hard disk.
5. After unlocking the HDD tray key lock with the key attached to the accessory, push the HDD
tray ejection to the right and the removable drive tray will pop open to remove the removable
tray.

6. Computer Setup
When the hardware setup for iR2823 / iR2824 is complete, you are now ready to turn the machine
on. After the hardware installation is complete, the iR2823 / iR2824 will be treated as one single hard
drive. When the computer is turned on, the system will retrieve the following information.
1. Device Manager Utility of Window OS will automatically detect the hard drive(s).
2. You can choose to format the hard drive by using the Disk Management tool of the operating
system before using the iR2823/iR2824.
At this point, the installation process is completely nished. The user can freely retrieve and save
data to iR2823 / iR2824 just like retrieving and saving data to a regular hard drive. If the user has any
problem during the operation, please refer to the Question & Answer (Q&A) section in Appendix.
2. RAID 0 mode
1). Place two new hard drives into R2823 / iR2824.
We would strongly suggest you to use two identical hard drives to get the maximum memory
capacity. And if the capacities of your two hard drives are difference, iR2823 / iR2824 only
recognizes the memory capacity at the small capacity hard drive.
2). Under RAID 0 mode, the total memory capacity of iR2823 /iR2824 would be double from the small
capacity hard drive. And also, RAID 0 mode will perform an excellent efficiency from its high
data transfer rate for user to read & write data.

Hard Disk Drive (HDD) Failure
Under the Mirror mode (RAID 1), what will be the total storage capacity when adding a brand
new HDD?
1. The total storage capacity at your iR2823 / iR2824 is determined by the storage capacity of
the primary HDD installed during the initial usage.
2. The storage capacity will not be increased even though you replace a larger capacity new
HDD.
Why does the error message appear when I install the second HDD?
The storage capacity of the new replaced HDD must be larger than the rst HDD.
Otherwise, iR2823 / iR2824 is unable to perform REBUILDING work.
Q1.
A:
Q2.
A:
About the Auto Rebuilding Function
What will happen if we turn o the computer power while iR2823 / iR2824 is still executing auto
REBUILDING work?
Under the Mirror mode (RAID 1), if computer power is o during REBUILDING work, iR2823 /
iR2824 will still remember the percentage of its REBUILDING work, and then resume it back to
its REBUILDING work while computer power is back on.
Is it possible to lose data during the REBUILDING work?
The REBUILDING work will automatically duplication data from one sector to another sector.
Technically speaking, the data should not be lost during its REBUILDING work. However, if the
original HDD is detected with too many bad sectors during the REBUILDING work, iR2823 /
iR2824 will make hypothetical duplication instead of treating the bad sectors as HDD failure.
Therefore, the data stored in the bad sectors could potentially be lost during REBUILDING work.
