Q2.
A:
After installing iR2622S, we are unable to start the computer or the computer can not locate
iR2622S upon startup.
1. Please check whether the readings on the iR2622S LCD display screen appear normal.
2. Please check whether the SATA Cable connection cables are properly connected to the
computer system and whether SATA drives are functioning normally.
3. If everything is functioning properly but the user still can not start the computer system, then
the problem might be the system incompatibility. If such incompatibility takes place, please
contact our technical support department.
When the iR2622S is in use, the computer system is functioning normally but the iR2622S
access speed is abnormal.
Please rst check whether the iR2622S is in the progress of executing data auto-rebuild.
1. Please examine if the length of the connection cables, SATA cable that connect the drives to
the computer system is too long and whether the specication these cables complies with the
requirements.
2. If both the lengths and specication of the cables are checked out ok, please turn off iR2622S
and remove the hard drive from iR2622S. Test the hard drive directly with the computer
system since it might be the bad sectors in the hard drive that are causing the longer than
normal system down time.
What will be the system’s total storage capacity when adding a brand new hard drive?
1. The total storage capacity for iR2622S is determined by the storage capacity of the primary
hard drive installed during the initial usage.
2. The storage capacity will not increase after initial installation even when place a brand new
hard drive with larger storage capacity.
Why does the error message appear when I installed the second hard drive?
The storage capacity of the second hard drive must be larger than the first hard drive.
Otherwise, iR2622S can not rebuild the new hard drive.

About Auto Rebuilding Function
What will happen if we turn off the computer’s power while iR2622S is still executing data auto
rebuilding?
If the power is out of the auto rebuilding process, the controller will remember when completion
percentage of the auto rebuilding process and resume the rebuilding process when the power is
back on.
Is it possible to lose any part of the data during the data auto rebuilding?
The data auto rebuilding function will copy data from one sector to another sector. Technically
speaking, the data will not be lost during the auto rebuilding process. However, if the original
hard drive is detected with bad sectors during the rebuilding process, iR2622S will make
hypothetical duplication instead of treat the bad sectors as hard drive failure. Therefore, the data
stored in the bad sectors could potentially be lost during rebuilding.
