Q&As 

General 

Q:

 When I have finished changing the RAID mode, how come the System cannot 

accept the change and is still in the previous mode? 

A:

 To make sure that the System accepts the RAID mode changes, you will need 

to power off the System first.  When you power it back on, the System will accept 
the changes.  It is highly recommended to always power off the RAID System 
before setting or changing the RAID Mode Switch to ensure that the changes are 
accepted by the System.  Please be cautioned that changing the RAID mode can 
delete all data in the System.   

HDD Capacity 

Q:

 All my HDDs are at least 1TB or above, will the RAID System be able to 

support the gigantic storage capacity?  

A:

 Yes, the RAID System will be able to support any HDDs over 1TB size 

capacity.  However, most older host systems cannot support over 2TB of total 
capacity, only Mac OS 10.3 and newer, and PC Windows Vista or newer.  In 
addition, based on the host system you have, there may be limitations on the port 
connections when the storage size is over 2TB.  Please see the chart below.
