Understanding and Changing RAID Policies
RAID 1 (often called “mirroring”) provides protection from disk errors and
single disk failure. With RAID 1, maximun capacity is limited to the size of one
of the two drives inside the enclosure. For example, a 1TB Duo Pro Drive is
limited to 500GB capacity (the size of each of the two drives inside the
enclosure) when used in RAID 1 mode. Total capacity is reduced because all
data is duplicated (“mirrored”) on both drives inside the enclosure.

The hard drive continues to operate so long as at least one drive is functioning.
However, if the LED on the front panel glows red, it means there is a failure in
one of the two drives of the RAID 1 configuration. If this occurs, you should
copy your data to another storage device and call Technical Support for
assistance.

Changing RAID Policies
You can change RAID policies at any time but you must do it properly or you
might lose data. The instructions that follow will guide you through the
process. Be sure and allow several hours for the rebuilding process to finish.
You can use the drive during this time, but it will add to the time it takes to
complete the policy change operation.

To change RAID policies:
Remove the hard drive partition before the mode change to remove the
existing data from the host – WARNING, all data will be lost when you change
RAID Policies. We strongly suggest that you back up any data currently on the
drive to an external location such as Fabrik Ultimate Backup or another hard
drive.
