(1) Please prepare at least 2 hard drives to set RAID mode. The hard drive is a precise
device. Please back up your important data timely and operate it carefully to avoid
improper operations leading to data errors or loss.
(2) For situations of setting or changing the RAID mode and adjusting the hard drive slot
order in RAID state will empty all files on all hard drives, so be sure to back up all
data first.
(3) When operating in RAID mode, do not remove your hard drive.
(4) In PM (Normal) mode, all hard drives in the hard drive enclosure are displayed and
work independently on the computer. Please note that if any of the hard drives is
unplugged or a new hard drive is inserted in this mode, the hard drive enclosure will
restart compulsorily, which will cause temporary disconnection of the other hard

(1) Please prepare at least 2 hard drives to set RAID mode. The hard drive is a precise
device. Please back up your important data timely and operate it carefully to avoid
improper operations leading to data errors or loss.
(2) For situations of setting or changing the RAID mode and adjusting the hard drive slot
order in RAID state will empty all files on all hard drives, so be sure to back up all
data first.
(3) When operating in RAID mode, do not remove your hard drive.
(4) In PM (Normal) mode, all hard drives in the hard drive enclosure are displayed and
work independently on the computer. Please note that if any of the hard drives is
unplugged or a new hard drive is inserted in this mode, the hard drive enclosure will
restart compulsorily, which will cause temporary disconnection of the other hard
drives.
(5) Following steps are for setting up RAID by hardware. For RAID Manager software,
please download the app from our official website. Please note that the RAID
