3. G-SPEED with capacities over 2TB must be configured to 
work properly with your operating system. 
a. Mac OS X Users: 
Set the item “Greater Two Terabyte Volume 
Support” to “64bit LBA”, this configures G-SPEED to 
report full capacity in MAC OSX 
b. Windows 64 Users: 
Set the item “Greater Two Terabyte Volume 
Support” to “for Windows”, this configures G-SPEED 
to report full capacity in Windows 64 (or Vista)  
c. Windows XP Users: 
Windows XP currently does not support disk volumes 
over 2TB in capacity (2048 GB). You must configure 
G-SPEED with multiple volumes of 2TB or less as 
described here: 
c1. Choose “Quick Create”, select your RAID level 
and leave the default setting of “No” under 
“Greater Two Terabyte Volume Support”. This will 
create the maximum Volume size of 2047.97GB 
(2199GB from disk) allowed in 32bit systems. 
c2. Continue to create Volumes on the G-SPEED by 
selecting “Create Volume Set” under the “VolumeSet 
Functions” on the left navigation bar. This screen will 
appear: 
c3. Hit “submit” to enter the configuration page. 
Select your desired RAID level, check “Confirm the 
Operation” and hit “Submit”. Continue this process 
until all available space has been used. 
This process will create multiple Volumes that will 
appear in Windows Disk Manager as disks ready to 
be formatted. It is possible to create one large 
Volume in Windows by “spanning” these logical 
disks. Refer to your OS documentation for details.
