Windows 2003 maximum volume size issue

We purchased a Sonnet Fusion D400QR5 hard drive enclosure and configured it with 4 2TB drives for a total of 8TB.  It’s configured for RAID 5 so we should have between 5 and 6TB of free space.  When we connected it to a Windows 7 laptop, we have over 5.5TB of free space.  When we hook it up to our 64 bit Windows 2003 SP2 server, we only see it as a 2TB drive in Disk Management.  I converted it to a dynamic disk and a GPT disk and it’s still only 2TB.  It is connected to our server using the ESATA connection. Why is it only showing only 2TB under Windows Server 2003 64bit?  We converted it to a dynamic disk and GPT disk so shouldn't we be seeing the full 5.5TB?  Thank you.

In Windows 2003 is the drive seen as GPT or Basic?
It could be also that your SATA controller does not support drives bigger than 2TB (motherboard limitation).

It's seen as a dynamic disk (GPT).

What is the model of the motherboard? You do not need it to be dynamic, if it is GPT then it should be ok.

I found out it was because of the driver of the esata card. They have a updated driver that corrects the 2TB limit.
