Q1After installing PD3500+, we are unable to start the computer or the computer can not locate PD3500+ upon startup.
1. Please check whether the readings on the PD3500+ 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.
Q2When the PD3500+ is in use, the computer system is functioning normally but the PD3500+ access speed is abnormal.
Please first check whether the PD3500+ 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 PD3500+ and remove the hard drive from PD3500+. Test the hard drive directly with the computer system since it might be the b
Q3Under 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 PD3500+ 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.
Q4Why does the error message appear when I installed the second hard drive?
1. The storage capacity of the second hard drive must be larger than the first hard drive. Otherwise, PD3500+ can not rebuild the new hard drive.
Q5What will happen if we turn off the computer’s power while PD3500+ is still executing data auto rebuilding?
Under the 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.
Q6Is 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, PD3500 + 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.
