Hard Disk Drive (HDD) Failure
Q1.
Under the Mirror mode (RAID 1), what will be the total storage capacity when adding a brand
new HDD?
A:
1. The total storage capacity at your IR2822 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.
Q2.
Why does the error message appear when I install the second HDD?
A:
The storage capacity of the new replaced HDD must be larger than the first HDD.
Otherwise, IR2822 is unable to perform REBUILDING work.

Q1.
REBUILDING work?
Under the Mirror mode (RAID 1), if computer power is off during REBUILDING work, IR2822
A:
will still remember the percentage of its REBUILDING work, and then resume it back to its
REBUILDING work while computer power is back on.
Q2.
Is it possible to lose data during the REBUILDING work?
A:
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, IR2822 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.
