Adaptec 4000SAS RAID Controller

We are trying to re-purpose a 3 year old server. It originally had 2 RAID arrays - one RAID 1 with two 80GB drives for the OS, then six 500GB drives in a RAID 5 for data. The RAID controller is an adaptec 4000 controller. The drives are all SATA. The RAID 5 was working fine until we replaced the drives.

I replaced the six 500GB drives with new 2TB drives. I left the two 80GB drives there to continue to run the OS. Now when I go into the RAID controller configuration utility, I still see the RAID 1, but I cannot create a new array with the new drives. If I go into the drive selection utility I can see the 6 new drives and even perform a format, but when I go into the  array configuration utility I cannot select any of the new drives, I cannot initialize the drives - it's like the aren't there.

I am thinking that the drives just are not compatible with the controller - although I have not seen anything in any documentation that identifies maximum drive size or any other limitations on the drives. Does anyone have any other suggestions before I start thinking about plan B?

Thanks in advance.

The 4000s has firmware from 2007 .so it was basically around before TB drives were even in production.
I very much doubt as to whether it will do 2tb drives ever.
Not to mention there are no drivers for anything past server 2003 and they are probably 4k sector which adds another layer of complexity.

There are other controllers out there (Dell H700) ,but they start at about $700 bucks and even then .I think you need an OS (64 bit) that will support GPT as a format as MBR maxes out at 2tb.

That's what I suspected. Thanks for confirming. Look's like I need to come up with a plan B.
