Only 2TB of Disk Capacity can be used


Only 2TB of disk capacity can be used when using larger disks, eg. 3TB, 4TB, 6TB and so on.

Root Cause

  1. Windows XP and previous versions do not support GPT partition style.
  2. Windows Vista and newer versions have not configured to be used with GPT partition style.
  3. The motherboard does not support UEFI.



  1. Use Windows Vista or newer versions.
  2. Be sure to create disk(s) using GPT partition style. Else, delete and re-create the partition using GPT (all current data will be wiped out).
  3. Be sure that the PC's motherboard support UEFI.
