Unstable system after connecting SR2611
Q: After installing SR2611, we are unable to start the computer or the computer can not
locate SR2611 upon startup.
A: 1. Please check whether the readings on the SR2611 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.
Q: When the SR2611 is in use, the computer system is functioning normally but the SR2611
access speed is abnormal.
A: Please first check whether the SR2611 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
SR2611 and remove the hard drive from SR2611. 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.
Hard Drive Failure
Q: Under the mirror mode (RAID 1), what will be the system’s total storage capacity when
adding a brand new hard drive?
A: 1. The total storage capacity for SR2611 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.
Q: Why does the error message appear when I installed the second hard drive?
A: 1. The storage capacity of the second hard drive must be larger than the first hard drive.
Otherwise, SR2611 can not rebuild the new hard drive and the LCD display screen will
display “Wrong Capacity”.
2. The LCD display screen might display rebuilding error messages such as
Pri(s)->Sec(s)or Sec(s)->Pri(s). The term (s) signifies that both hard drives are treated
as original hard drive. The user must determine which hard drive will be the original
hard drive prior installing the hard drives into SR2611. Once the original hard drive is
designated and installed in SR2611, the user can place in the second hard drive by
taking advantage of SR2611’s Auto Rebuilding function.
Q: My hard drive is obviously operating properly but why is it shown as failed in the SR2611
display?
A: SR2611 uses more strict requirements and standards to examine the bad sectors in the
hard drive. The user can first overwrite the bad sector on a PC before placing the hard
drive into SR2611.
