Q2.
A:
After installing , we are unable to start the computer or the computer can not locate
upon startup.
1. Please check whether the readings on the 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 is in use, the computer system is functioning normally but the
access speed is abnormal.
Please first check whether the 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 specification these cables complies with the
requirements.
2. If both the lengths and specification of the cables are checked out ok, please turn off
and remove the hard drive from . 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.
Under the mirror mode (RAID 1), what will be the system’s total storage capacity when adding a
brand new hard drive?
1. The total storage capacity for 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, can not rebuild the new hard drive.

About Auto Rebuilding Function
What will happen if we turn off the computer’s power while is still executing data auto
rebuilding?
he mirror mode (RAID 1), 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, 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.
