Please first check whether if iR2022 is executing the auto REBUILDING work. If it works for REBUILDING, your iR2022 is a good device. And if it doesn’t, please follow the following two ways to find out the possible root cause:
1. Please examine if your SATA cable is too long and will attenuate signal, or whether if the Two SATA cables fail to meet the cable specification requirements.
2. If the two cables meet the requirements at both the specification & length, please turn off the computer, remove the two hard drives from iR2022, and directly connect the hard drives to computer, format them, and then try to read/write data into them. You may find out that the hard disk (s) are with unacceptable bad sector quanty.
